Key Weather Metrics and Data Sources
Winter in Pattaya brings drier air, slightly cooler temps, and more predictable sunshine than the rest of the year. The tropical climate stays steady, with only minor shifts in temperature, rainfall, and daylight—perfect for spending time outdoors.
Temperature Ranges and Averages
In the winter months, average daytime temperatures sit between 28°C and 31°C (82°F–88°F). Nights cool to about 22°C–24°C (72°F–75°F), which feels nice but never cold.
Historical data shows Pattaya almost never gets extremely cold. The dew point hangs around 20°C–23°C (68°F–73°F), so the air feels humid but not nearly as heavy as in the rainy season.
Sea surface temperatures stay close to 28°C (82°F–84°F), so you can swim whenever you want. Coastal breezes help keep the climate steady and stop any sudden heat spikes.
Precipitation and Rainy Days
Winter is the dry season, with rainfall dropping way down after the monsoon. December averages just 8 mm (0.3 in) of rain, usually over 1–2 days.
By February, totals are still low, around 20–30 mm (0.8–1.2 in), with only a few scattered showers.
Compare that to September and October, when rainfall jumps above 200 mm (8 in). Winter always sees the lowest rainfall of the year.
Humidity also drops, averaging 70%–75%, which makes walking tours and outdoor trips much more comfortable. Some dampness lingers, but the lack of wet days makes planning way easier.
Sunshine Hours and Daylight
Pattaya gets about 11 to 12 hours of daylight per day in winter. That’s a bit shorter than summer, but it doesn’t really limit your plans.
On average, you get 7–8 hours of sunshine daily, which beats the gloomier monsoon months. With lighter cloud cover, you’ll enjoy brighter skies and more reliable sun.
The UV index stays high, often reaching 10–12, so don’t forget sun protection, even in the cooler months. Lower rainfall, steady daylight, and long sunshine periods make winter a top time for anything outdoors.
Comparing Pattaya’s Winter to Other Seasons
Winter in Pattaya means drier skies, less humidity, and way more comfortable conditions outside. The rainy months and hotter spring period each bring their own challenges for visitors and locals.
Differences from the Rainy Season
You’ll really feel the difference when you compare winter to the rainy season. From June to October, Pattaya’s savanna climate delivers frequent downpours, with rainfall often topping 200 mm per month at its peak.
Rainy days can stack up to 18 per month, making it tough to count on outdoor plans.
In winter, rain almost disappears. December averages just 8 mm, often with only a single rainy day. The air loses that heavy, sticky feeling, with humidity dropping to about 70%. That makes sightseeing, walking, and beach days so much easier.
Temperatures stay warm in both seasons, usually between 30–32°C (86–89°F). But in winter, the lack of constant clouds means you get more sunshine hours. Even when the thermometer looks the same, the climate feels totally different.
Visibility is another plus. In the rainy season, heavy showers and thick humidity can make the sea and coast look hazy. In winter, skies clear up and Gulf waters calm down, which is great for water sports and boat trips.
Transition Into Spring and Hotter Months
When winter ends, Pattaya shifts into hotter spring weather. By March and April, highs climb to around 32–33°C (90–91°F). Humidity rises, and rainfall jumps from about 50 mm in March to over 140 mm in May, signaling the wet season’s return.
April feels especially different, with heat peaking. High UV levels and less breeze can make afternoons uncomfortable unless you find shade or a cool spot. Unlike winter, when you can enjoy hours outside, spring often means planning your day around the hottest times.
Sea temperatures rise too. In winter, the Gulf sits near 28–29°C (82–84°F), so swims feel refreshing. By late spring, the water heats up to about 30°C (86°F), which isn’t as cooling when it’s blazing hot out.
Daylight stays steady year-round, but spring brings more clouds. You might get less direct sunshine, even if the days are technically longer. That, plus the rising humidity, marks the clear end of Pattaya’s dry, mild winter.
Winter Weather Impacts on Travel and Activities
Pattaya’s mild daytime temperatures, lower humidity, and limited rainfall make sightseeing and outdoor recreation surprisingly comfortable in winter. The sea stays warm enough for swimming, so you don’t need to worry about chilly water ruining your plans.
Cultural events and seasonal festivals pop up everywhere, giving you even more reasons to get out and explore the city.
Best Outdoor Activities During Winter
You’ll find Pattaya’s beaches much more pleasant in winter. The air feels warm, but it doesn’t smother you with humidity.
Daytime highs usually land around 28–30°C, and evenings cool off to about 23–24°C. With so little rainfall, you can make plans without constantly checking the weather.
Walking along Pattaya Beach Road or just lounging at Jomtien Beach feels way better than during the hotter months. Clear skies open up chances for day trips to nearby islands like Koh Larn, which are honestly hard to resist.
Outdoor spots such as the Sanctuary of Truth and Nong Nooch Tropical Garden become much easier to enjoy since the heat isn’t overwhelming. You might even want to use those long sunny days for golf, cycling, or a bit of hiking in the hills around town.
Sea Temperatures and Water Sports
The Gulf of Thailand keeps its warmth in winter, with sea temperatures floating around 27–29°C. You can swim comfortably and dive into water sports all season long.
Snorkeling, jet skiing, parasailing, and diving all stay popular. Calmer seas mean you don’t have to worry so much about strong waves, which is great if you’re just getting into water sports.
Boat trips to offshore islands usually run as planned since winter weather brings fewer storms. Underwater visibility also gets better, so divers and snorkelers get a clearer look at coral reefs and marine life.
Local Events and Festivities
Winter brings Pattaya’s busiest tourist season, and honestly, you’ll notice the difference. Events and activities seem to pop up everywhere, with street markets and cultural shows making the most of those dry evenings.
You might stumble upon traditional Thai festivals, temple fairs, or music events. The dates change from year to year, but the cooler season tends to draw both local and international performers.
With so many visitors, restaurants, bars, and nightlife venues stay buzzing. If you want to catch a popular show or stay at a favorite hotel, it’s smart to book ahead—places fill up fast during peak season.
Long-Term Weather Trends and Climate Insights
Pattaya’s winter comes from its tropical savanna climate, so you get lower rainfall, steady warmth, and fairly consistent humidity. Long-term records point to stable seasonal patterns, but honestly, with global climate changes, it’s hard not to wonder how future winters might look.
Historical Winter Weather Patterns
Weather data shows that Pattaya’s winters, running from November through February, are the driest months all year. Rainfall drops below 80 mm in November and usually falls to less than 10 mm in December. December stands out as the most reliably dry month.
Temperatures don’t really swing much in winter. Daytime highs average 29°C to 31°C (84°F to 88°F), while nighttime lows hover around 22°C to 24°C (72°F to 75°F). You won’t get those sharp temperature drops you’d find up north.
Humidity also eases up a bit in winter. The annual average sits between 70% and 83%, but the dry season brings it closer to the lower end, making outdoor activities more comfortable than in the sticky summer heat.
Sea temperatures stay inviting, averaging 28°C to 29°C (82°F to 84°F), so swimming and water sports don’t really stop for the season. As rainfall backs off, you get about 7–8 hours of good daylight most days.
Climate Change Considerations for Pattaya
Long-term climate models hint that Pattaya could see some subtle, yet pretty important changes in its winters down the road. The dry season will probably stick around, but shifts in rainfall timing and intensity might make December and January weather less predictable.
Rising sea surface temperatures in the Gulf of Thailand worry a lot of people. Warmer waters tend to bump up local humidity and sometimes trigger heavier rain, even when it’s supposed to be dry.
This shift could actually shrink the most comfortable window for travelers. It’s something to keep in mind if you’re planning a visit.
Global warming’s impact on heat stress is hard to ignore. Average winter highs might hit 32°C (90°F) more often, which isn’t great news for outdoor activities or your health.
UV levels will likely stay high, so sun protection should always be on your checklist. Slathering on sunscreen might not be optional anymore.
Winter still brings the most stable weather, but Pattaya’s climate record shows small shifts in temperature, rainfall, and sea conditions do happen. These changes might not feel huge each year, but over decades, they could really affect how you experience the city.
