Spring in Pattaya means hot days, warm nights, and a noticeable shift toward the rainy season. You’ll see daytime temperatures hover around 31–33 °C (88–91 °F), while nights usually stay near 25–27 °C (77–80 °F).
Humidity creeps up as spring goes on. By May, short but heavy showers often signal the monsoon’s arrival.
March and April still deliver plenty of sunshine, so it’s a favorite time for beach trips and outdoor fun. The sea stays welcoming at about 29–30 °C (84–86 °F), perfect for swimming.
By May, the air feels stickier, but rain tends to fall in bursts, leaving stretches of blue sky in between.
If you’re thinking of visiting in spring, you’ll need to juggle the heat with the growing chance of rain. The season brings a mix of long sunny afternoons, warm sea conditions, and those sudden downpours that cool everything off.
It’s a dynamic time to experience Pattaya, whether you want to sprawl on the sand or explore the city.
Overview of Spring Weather in Pattaya
Spring in Pattaya means steady warmth, high humidity, and more frequent rainfall.
You’ll notice tropical conditions that don’t change much in temperature, but the air definitely feels heavier than in cooler months.
Typical Temperature Ranges
During spring, Pattaya’s daytime highs usually stick near 30–32°C (86–90°F). Nights cool off a bit, often settling around 25–27°C (77–81°F), so it’s still warm.
The sea stays comfortable for swimming, with water temperatures averaging 29°C (84°F).
Pattaya’s spot on the coast helps keep temperatures from going extreme, unlike some inland Thai cities. But when you pair the heat with humidity, it can feel a lot warmer than the thermometer says.
Pack light clothes and drink water often to stay comfortable.
General Climate Characteristics
Pattaya has a tropical wet and dry climate, so spring falls right in the transition from the hot season into the rainy season.
Humidity levels climb, often above 75%, making the air sticky.
Rainfall starts picking up by late spring, with more showers in May. These downpours are usually short but heavy, and sunshine returns quickly.
Winds blowing in from the Gulf of Thailand offer some relief, though they also carry more moisture.
Sunlight stays strong, with daylight lasting about 12–13 hours. UV levels run high, so don’t skip the sun protection, even if it’s cloudy.
Comparison With Other Seasons
Compared to the cool season (November–February), spring feels hotter and much more humid. You won’t get that crisp, fresh air from earlier months, and outdoor activities might leave you feeling drained.
Against the rainy season (June–October), spring is a bit drier, though May already brings more wet days. You’ll see fewer storms than during peak monsoon, but the weather’s less predictable than in winter.
When you look at the hot season peak of March–May, Pattaya’s coastal breeze keeps the worst of the heat at bay. While inland cities might hit 35°C (95°F) or higher, Pattaya usually stays a few degrees cooler, making the climate a bit easier for visitors.
Monthly Weather Breakdown: March, April, and May
Through spring in Pattaya, temperatures climb, humidity rises, and rainfall shifts from light to heavy as monsoon season nears.
You’ll get hot afternoons, warm nights, and a clear change in comfort from March to May.
March Weather Details
March brings average daytime highs of about 31–32°C (88–90°F) and nighttime lows near 25°C (77°F). Humidity stays moderate, so it’s warm but not unbearable yet.
Rainfall picks up a bit from February, with about 55 mm spread over a handful of days. Showers tend to be short and scattered, so most days stay dry and sunny.

The sea averages 29°C (84°F), so swimming feels great.
April Weather Patterns
April turns up the heat—it’s the hottest month in Pattaya. Daytime highs often hit 33°C (91°F), and nights stick around 26°C (79°F).
The heat feels more intense as humidity climbs before the monsoon.
Rainfall rises to about 65 mm over several days, but those showers don’t last long, and sunshine follows. There’s more cloud cover than in March, but daylight is still long and bright.
The sea warms to about 30°C (86°F), ideal for water fun. Still, sightseeing midday can get uncomfortable. Light clothes, sunscreen, and lots of water are must-haves if you’re out and about.
April’s weather is hot, humid, and a bit wetter, hinting at the rainy season ahead.

May brings hot, humid, and much wetter days, marking the real start of monsoon season along Thailand’s coast.
Rainfall and Humidity Trends in Spring
Spring in Pattaya brings rising heat, more humidity, and a steady increase in rain as the rainy season approaches.
You’ll notice more wet days in May than in March, and the air gets heavier with moisture.
Average Rainy Days and Precipitation
Rainfall in Pattaya during spring climbs steadily. March is usually the driest, with about 4 rainy days and around 2 inches (50 mm) of precipitation.
By April, showers show up more often, averaging 6 rainy days and nearly 3 inches (70 mm) of rain.
May marks the shift toward the rainy season. You’ll often get 8 rainy days and rainfall totals close to 5 inches (115 mm). These showers come quick and hard, typical for the tropics.
Here’s a quick summary of the average rainfall pattern:
| Month | Rainy Days | Precipitation (inches) |
|---|---|---|
| March | 4 | 2.1 |
| April | 6 | 2.7 |
| May | 8 | 4.6 |
With this steady rise, you’ll want to prepare for wetter afternoons and the chance of travel delays, especially later in spring.
Humidity Levels Throughout Spring
Humidity gets higher as spring goes on. In March, relative humidity averages about 74–76%, which feels sticky but manageable, especially with sea breezes.
By April, levels climb to 78–80%, making daytime heat feel even stronger.
May brings humidity up to 81–82%. With highs near 90°F (32°C), the air can feel downright heavy, especially away from the water.
Mornings feel a bit better, but afternoons get muggy after rain. If you stick near the sea or shady spots, the humidity won’t feel as overwhelming.
This rise in moisture signals Pattaya’s wet season is just around the corner.
Sunshine Hours and Daylight Length
Spring in Pattaya means lots of bright weather. Daylight hours stay steady, so you get plenty of time outside—whether you’re relaxing on the beach or exploring the city.
Average Daily Sunshine
You can expect about 8 hours of sunshine per day in spring. March through May are some of the sunniest months around here.
The sun’s strong, so plan for protection if you’re outside a lot.
Mornings usually start clear, with short rain showers sometimes popping up later. Even with those quick downpours, sunshine hours stay high compared to the monsoon.
Here’s a look at average sunshine by month:
| Month | Avg. Sunshine Hours/Day |
|---|---|
| March | ~8 hours |
| April | ~8 hours |
| May | ~7–8 hours |
These long, sunny days make spring perfect for swimming, day trips, or sightseeing.
Changes in Daylight Duration
Daylight in Pattaya doesn’t shift much through spring. In March, you get about 12 hours of daylight, with sunrise near 6:30 a.m. and sunset around 6:25 p.m.
By May, days stretch a bit longer to nearly 12 hours and 40 minutes.
You’ll notice a little extra time in the evenings as spring goes on. It’s not a huge difference, but it helps when you’re planning your day.
Because daylight remains steady, you won’t have to worry about sudden changes in timing. This makes it easy to schedule what you want to do without stressing about early sunsets.
Sea Water Temperatures and Beach Conditions
Warm sea water is a given during spring in Pattaya, so the beaches stay inviting for swimming and more.
Conditions shift a bit from March to May, as both air and water temperatures rise and rainfall increases near the end of the season.
Average Sea Water Temperature
The Gulf of Thailand keeps things toasty. March averages about 29.2°C, April goes up to 30.2°C, and May reaches around 30.9°C.
These numbers sit well above the global average for tropical seas.
From March to May, water temperatures rise as the air heats up. Even at night, the sea stays warm, so you won’t get any chilly shocks.
For reference, Pattaya’s yearly average sea temperature is about 29.2°C (84.6°F). That makes spring—especially May—one of the warmest times for a swim.
Suitability for Swimming and Water Activities
High water temperatures mean Pattaya’s beaches are great for long swims. The sea feels more like a warm pool than the open ocean.
March and April bring more sun and less rain, so you’ll get clearer water and better visibility. By May, rain picks up and clouds roll in, but swimming is still comfortable.
The sea usually stays calm, which is great for families and anyone less confident in the water. Divers enjoy the warmth, though rains later in spring can cut visibility a bit.
Most visitors find the beaches very usable all season long.
Travel Considerations for Visiting in Spring
Spring in Pattaya gives you hot days, humid air, and the occasional rain shower. You’ll want to plan for both outdoor activities in the heat and those quick bursts of wet weather, while also thinking about the strong sun and warm sea temperatures.
Best Activities for Spring Weather
Pattaya’s daytime temperatures in spring usually hit 32–34 °C (90–93 °F). Nights don’t cool down much, hanging around 25–27 °C (77–80 °F).
The sea feels warm at about 30 °C (86 °F), so swimming’s pretty enjoyable.
People flock to the beach, but the afternoon sun can get overwhelming. If you’re not a fan of heat, try swimming or walking early in the morning or later in the afternoon.
During midday, I’d rather escape inside to a museum, a shopping center, or maybe a shady café.
April and May bring short rain showers, though they usually don’t last long. You can still make outdoor plans if you’re willing to adjust a little.
Places like the Sanctuary of Truth or Nong Nooch Tropical Garden give you a mix of shaded spots and indoor things to see.
If nightlife’s your thing, evenings feel much nicer than the day. Outdoor dining and a stroll along Beach Road get way more inviting after sunset.
Packing Tips for the Season
Pack light clothing made from breathable fabrics like cotton or linen. Loose shirts, shorts, and dresses really help you stay cooler in humid air.
Don’t forget a wide-brimmed hat, UV-rated sunglasses, and strong sunscreen. These make a huge difference when it comes to sun protection.
Showers happen often, so toss in a compact umbrella or a lightweight rain jacket. Streets can get slippery fast, so waterproof sandals or quick-dry shoes beat heavy footwear by a mile.
In the evenings, you might want a thin long-sleeve shirt to keep mosquitoes at bay. Planning to visit temples? Remember to bring modest clothing that covers your shoulders and knees.
A refillable water bottle comes in handy and helps you stay hydrated in the heat.
