Thailand Weather in November: Regional Guide, Temperatures, Rain & Best Places
It marks the start of the cool, dry season for most regions, bringing lower humidity, far fewer rainy days, and more predictable sunshine. The Andaman Sea coast usually turns beach-friendly, while the north enjoys warm days and pleasantly cool nights. This guide explains temperatures, rainfall patterns, sea conditions, regional differences, festivals, and practical tips so you can choose the best places to go.
November at a glance (fast facts)
Typical temperatures and humidity
Across Thailand in November, daytime temperatures are warm without being extreme. Expect average highs of about 28–30°C in the north (Chiang Mai and Chiang Rai) and roughly 30–32°C in Bangkok and much of the south. Nighttime lows often dip to around 17–20°C in the north, while Bangkok and the southern coasts usually remain closer to 23–25°C overnight.
Humidity drops compared with the wet season, improving overall comfort. Typical relative humidity ranges hover near 65–70% in the north and 70–75% in Bangkok and the south, though morning hours can feel a touch more humid. The day–night contrast is most noticeable in the northern highlands, where early mornings can feel fresh and a light layer is welcome. As the month progresses, shade and breezes reduce the heat index for outdoor touring.
Rainfall patterns and sunshine hours
The Andaman coast (Phuket, Krabi, Khao Lak) usually sees a sharp reduction in rainfall as its dry season begins, with indicative monthly totals often in the 100–180 mm range and many days fully dry. In contrast, the Gulf islands (Koh Samui and Koh Pha Ngan) can be wetter in November due to the northeast monsoon, often recording higher monthly totals and more frequent rainy days.
Sunshine increases broadly, with many areas reaching about 7–9 hours of sun on typical days. Showers, if they occur, tend to be shorter and more localized than in September and October. Keep in mind that the exact timing of the monsoon’s retreat varies year to year. A slow-moving system or lingering disturbance may temporarily boost rain, especially early in the month, even as the overall trend favors brighter, drier weather.
Early vs late November differences
Conditions often improve week by week. In early November (week 1), leftover showers can still pass through both the Andaman side and the Gulf. By week 2, the Andaman coast usually trends drier, while the Gulf side may still see unsettled spells. Week 3 typically brings calmer seas and longer sunny windows on the Andaman coast, while the Gulf may continue with periods of rain and cloud. By week 4, beach weather on the Andaman is commonly reliable, with better sea clarity and fewer interruptions.
There are notable exceptions. A persistent low-pressure system or a late tropical disturbance can temporarily increase rainfall or swell, even on the Andaman side. Festival periods around the full moon may also affect crowds and availability regardless of weather. Prices and occupancy rise toward December’s peak, so late-November stays, especially at beaches, can book out quickly when conditions turn consistently fine.
National overview: season shift and comfort
Transition to the cool, dry season
November marks a decisive shift to the cool, dry season across most of Thailand. After months of higher humidity and frequent showers, the atmosphere becomes more stable and pleasant for travel. Outdoor plans are easier to keep, and long city or countryside days are more comfortable than in the wet-season peak.
This change is largely shaped by the northeast monsoon, which brings drier continental air across much of Thailand. In simple terms, winds start to blow from the northeast, carrying less moisture to inland and western areas. However, this same pattern pushes moisture onto the Gulf of Thailand side, which is why the Gulf islands can be wetter in November. Meanwhile, the northern highlands cool down at night but remain warm under bright daytime skies, creating excellent conditions for trekking, scenic drives, and festivals.
Daylight, UV, and comfort levels
Daylight in November is close to 11–12 hours depending on latitude, with sunsets earlier than mid-year. Even though conditions are cooler and less humid, the UV index often remains high, commonly reaching 9–11 at midday. Sun protection matters: apply SPF 30+ sunscreen, wear a hat and sunglasses, and seek shade during peak hours when possible.
Lower humidity and light breezes reduce heat stress for city sightseeing, making museum visits, walking tours, and market browsing more comfortable. Air quality is generally good this time of year, and the northern smoke season is still months away. Practical tips include drinking water throughout the day, adding electrolytes during active excursions, and planning indoor or shaded breaks around noon to balance comfort and energy levels.
Regional weather breakdown
North (Chiang Mai, Chiang Rai): warm days, cool nights
The northern region greets November with bright skies, warm afternoons, and refreshing evenings. Typical highs sit around 28–30°C with relatively dry air, making city strolls and countryside drives a pleasure. Rainfall is minimal, and scenic visibility is usually excellent because haze is not a concern in November.
Nights often fall to 17–20°C in the valleys, and mountain areas can dip lower, especially at dawn. Trekkers and sunrise chasers should bring a light layer for early mornings and evenings. The combination of warm days, low rain, and crisp nights creates ideal conditions for hiking, temple visits, night markets, and photography across Chiang Mai and Chiang Rai provinces.
Central (Bangkok): warm, lower humidity, brief showers
Bangkok in November is warm but markedly less humid than in September and October. Expect daytime highs around 30–32°C and nights near 23–24°C. While showers can still occur, they are usually brief and localized, which makes it feasible to plan full-day itineraries that blend indoor and outdoor stops.
Urban heat can build on paved streets, so schedule indoor breaks during midday. Short late-afternoon showers are still possible, often clearing quickly. The city’s parks, riverside paths, and open-air markets feel more comfortable overall, and the combination of early sunsets and warm evenings helps set a pleasant tone for dining outdoors or joining cultural events.
Andaman west coast (Phuket, Krabi, Khao Lak): improving beach weather
November brings steady improvement to the Andaman coast. Rain and swell typically decrease through the month, turning beach days more reliable with each passing week. Early in November, some areas may still see short showers and occasional red flags after passing systems, but these interruptions become less frequent over time. Sea temperatures hover around 28–30°C, ideal for swimming.
As runoff subsides, visibility improves for snorkeling and diving, especially from mid to late November. Early in the month, remaining rainfall can be closer to the 120–180 mm range, but it usually drops significantly by late month. The Similan area and offshore sites often see a notable lift in conditions once seas calm, making late November a strong window for marine excursions and island-hopping.
Gulf east coast (Koh Samui, Koh Pha Ngan): wetter month caveat
The northeast monsoon brings frequent rainy days and longer cloud cover to the Gulf islands in November. While sea temperatures remain warm around 29°C, the water can be choppier, and visibility may be reduced by runoff and wave action. Beach time is less reliable than on the Andaman side this month, and boat trips may face weather-related changes or cancellations.
Plan flexible days with wet-weather alternatives such as cooking classes, spa and wellness sessions, cafes, indoor markets, or temple visits. When seas are unsettled, check ferry advisories, choose larger boats when possible, and expect occasional schedule adjustments. Local operators monitor conditions daily and can suggest safe windows for travel and activities.
Eastern exceptions (Koh Chang, Koh Kood): favorable alternatives
The eastern seaboard often shapes up as a favorable alternative in November. Koh Chang and Koh Kood commonly transition to drier conditions during the month, with increasing sunny intervals and calmer seas, especially toward the latter half. These islands can deliver quieter beaches compared with the Andaman hotspots while still offering comfortable temperatures and a relaxed pace.
Access is straightforward from Bangkok: fly to Trat and transfer by road and ferry, or travel by bus or minivan from the Ekkamai terminal. Ferry schedules can adjust with weather, so confirm the latest timings and allow buffer time for connections. While passing showers remain possible, week-to-week variability often trends toward more settled days by late November.
City and island quick facts (temperatures, rain, sea)
Bangkok weather in November
Bangkok is warm with lower humidity than in the wet-season months. Average highs and lows are approximately 31/24°C, and rainfall is usually limited to a few short showers. Many days are entirely dry, supporting full-day sightseeing with smart pacing and shade during midday hours.
Walking tours are most comfortable in the morning and evening. Aim for early starts around 6:30–9:00 for cool air and softer light, then resume longer walks after about 16:30 when the sun eases. Light, breathable clothing works best for evenings, and indoor museum or market stops help keep energy levels steady through the day.
Chiang Mai weather in November
Chiang Mai enjoys clear skies, very low rainfall, and a comfortable day–night split in November. Expect roughly 29°C in the afternoon and about 18°C at night around the city. The dry air supports excellent visibility for scenic viewpoints and historic old-town explorations.
If you plan mountain day trips to Doi Inthanon, Doi Suthep, or Doi Pha Hom Pok, early morning temperatures can be much cooler than in the city, sometimes near the low teens Celsius. Pack a light jacket or sweater for sunrise visits and night markets. Festivals around the full moon bring special evening activities and lantern displays.
Phuket weather in November
Phuket transitions to its dry season in November, with falling rain frequency and more sunshine as the month progresses. Average temperatures hover near 30°C by day and around 24°C at night. Short showers can still occur early in the month, but they tend to be brief and localized.
The sea is warm at about 29°C, and snorkeling and boat trips usually improve in mid to late November as visibility rebounds after the wet season. While some west-coast beaches may still experience currents after storms, red-flag days become less common later in the month. Sea visibility is typically best toward the second half of November.
Krabi and Khao Lak weather in November
Krabi and Khao Lak follow a similar pattern to Phuket, with steady improvement through November. Island access to destinations such as Phi Phi and the Similan Islands usually resumes in line with calmer seas. Water clarity often strengthens in mid to late month as runoff declines.
Short-lived showers may still pop up, mainly early in November. After heavy rain or rough seas, some marine parks or boat operators may temporarily close or modify schedules for safety. Local dive and tour centers offer the most current guidance on conditions and closures.
Koh Samui weather in November
November is typically the rainiest month for the Samui–Pha Ngan–Tao cluster. Expect many wet days and cloud cover, even though the sea remains warm around 29°C. Beach reliability is lower than the Andaman coast or the eastern alternatives this month.
Set expectations for sunshine windows rather than full days of sun. Plan flexible itineraries that can shift between indoor and outdoor options as conditions change. On days with improved weather, focus on short beach sessions or quick boat trips as windows allow.
Koh Chang and Koh Kood weather in November
Koh Chang and Koh Kood often transition toward drier conditions across November, with highs around 30°C and increasing sunny intervals. The sea is warm, and calm periods become more frequent later in the month, offering a relaxing pace without the busyness of the Andaman’s main hubs.
Microclimates can vary between west- and east-facing beaches. West-facing shores may see a touch more swell or passing showers, while east-facing areas can be slightly more sheltered. Early in the month, occasional showers are still possible, so keep plans flexible on arrival.
Sea and beach conditions in November
Sea temperatures and visibility
On the Andaman side, visibility tends to recover as the month advances, often moving into the 10–25 m range once runoff settles and seas calm. This improving clarity is a key reason many divers and snorkelers favor late November in places such as the Similan Islands.
Gulf-side water is equally warm, but rainfall and cloud can limit beach time and reduce visibility. Surf and currents diminish on the Andaman through the month, with more frequent green-flag days later on. For any marine activity, it is wise to check daily forecasts and sea conditions with local operators, who monitor winds, swell, and visibility in real time.
Best coasts and islands to choose
If your priority is beach time, the Andaman coast is generally the best bet in November as it shifts firmly into the dry season. Phuket, Krabi, and Khao Lak deliver improving sunshine, calmer seas, and rising water clarity as the month progresses.
The Gulf islands can be a gamble in November due to the northeast monsoon. While there can be sunny breaks, rainy days are common, and seas may be choppy. Match your plans to the conditions: late-month snorkeling and diving typically favor the Andaman, while wellness, cafes, and cultural activities can be a better focus for the Gulf if you must travel there in November.
| Coast/Islands | Rain tendency | Sea state | Best for |
|---|---|---|---|
| Andaman (Phuket, Krabi, Khao Lak) | Dropping through November | Calming; improving visibility | Beach days, snorkeling/diving (late month) |
| Gulf (Samui, Pha Ngan) | Frequent rainy days | Choppier; reduced visibility | Flexible plans, wellness, indoor activities |
| Eastern (Koh Chang, Koh Kood) | Often moderate with sunny spells | Increasingly calm late month | Quieter beaches, relaxed stays |
Festivals and events in November
Loy Krathong (date, where, what to expect)
Loy Krathong is celebrated nationwide on the full moon of the 12th lunar month, which typically falls in November. People float decorated krathongs made of banana leaves and flowers on rivers, lakes, and canals to give thanks and release misfortune. Major events take place in Bangkok and Chiang Mai, and many towns organize performances, market stalls, and parades near waterways.
Dates vary every year because the holiday follows the lunar calendar, so verify the local schedule and permitted celebration areas. In 2025, the date is expected around November 6. During crowded moments along riverbanks, be mindful of water safety and respectful behavior, keeping walkways clear and avoiding litter. If in doubt, follow local guidance for where and how to participate.
Yi Peng in Chiang Mai (date, viewing tips)
In 2025, key nights are expected around November 5–6. While images of mass lantern releases are popular, sanctioned events require tickets and follow safety rules to protect communities and the environment.
Plan for large crowds, traffic control, and early arrival at viewing spots. Consider attending an official lantern-release event if you wish to participate, and avoid unsanctioned releases, which can be unsafe and non-compliant with local regulations. If tickets sell out, there are still many atmospheric ways to enjoy Yi Peng from riverside promenades, temple courtyards, and organized city festivities.
What to pack and practical travel tips
Clothing and footwear
Choose breathable, quick-dry fabrics for warm days across Thailand, and add a light layer for northern evenings. Comfortable walking shoes are essential for city touring, while sandals suit beaches and casual wear. A compact rain jacket or poncho is useful for brief showers, especially early in the month on the Andaman side or for the Gulf islands.
Day–night changes vary by region. In the north, cool dawn and evening temperatures make a light jacket, long-sleeve top, or scarf practical. In Bangkok and the south, nights remain warm, so lightweight clothing suffices. Pack outfits that can meet temple dress codes when layered, such as a breathable T-shirt under a button-up shirt and long trousers or a midi skirt over leggings.
Sun, insects, and health considerations
UV levels remain high in November. Use SPF 30+ sunscreen, a hat, and sunglasses, and seek shade during midday hours. Insect repellent containing DEET or picaridin helps for evenings, especially near vegetation and water. Carry after-bite relief and basic medications, and consider adding electrolyte packets for active days in the heat.
Travel insurance is recommended for medical coverage and trip disruptions. Clinics and hospitals are widely available in major hubs such as Bangkok, Chiang Mai, Phuket, and Samui, and pharmacies are common in cities and resorts. Drink safe water, and if you are sensitive to heat, schedule breaks and hydrate regularly to maintain comfort and energy.
Temple etiquette
Many travelers carry a lightweight scarf or shawl to drape over shoulders and choose breathable long pants or a long skirt for day trips that include sacred sites. Shoes must be removed before entering temple buildings, so footwear that is easy to slip on and off is practical.
Be respectful during ceremonies and festival nights around temples by keeping voices low and avoiding restricted areas. Drones and photography may be limited; look for posted signs and ask if unsure. A simple approach is to pack one “temple-ready” outfit that layers easily, so you can move from outdoor sightseeing to religious sites without changing your entire wardrobe.
Crowds, prices, and when to book
Shoulder season dynamics
November is a shoulder month that trends into Thailand’s high season. As dry, sunny weather settles in, crowds grow from mid to late month, with the Andaman coast seeing the most pronounced uptick. Early November often offers better availability and occasional deals, especially before marine conditions stabilize.
Festival periods can cause short-term surges in demand regardless of weather. Chiang Mai, in particular, experiences crowd spikes around Yi Peng and Loy Krathong, with accommodations and flights booking up weeks in advance. Toward the end of November, beach destinations see rising occupancy as travelers arrive ahead of the December–January peak.
Budget ranges and booking windows
Flexible rates and free-cancel options can help you adapt to variable weather, especially if you are considering the Gulf islands. Northern cities remain good value, though rates climb in December as holiday demand builds.
As a general guide, 3–6 weeks ahead is a workable booking window for early-November stays, while 6–10 weeks ahead is safer for late-November dates at popular beaches or in Chiang Mai around festivals.
