Pattaya features a tropical climate with hot weather year-round, a pronounced dry season from November to February, and a rainy season from May to October. The city enjoys abundant sunshine in the dry months and warm sea temperatures throughout the year, making it a popular destination for beachgoers and outdoor enthusiasts in every season.
Pattaya’s climate is shaped by its coastal location on the Gulf of Thailand, resulting in three main seasons: a cool, dry season (November–February), a hot season (March–May), and a rainy season (June–October). Temperatures are consistently warm, with average daytime highs ranging from 30°C in December to 34–35°C in April. Nights are balmy, typically 22–27°C, and humidity varies from moderate in the dry season to high during the rains.
The dry season (November–February) offers the best weather, with clear skies, low humidity, and minimal rainfall – often just 1–3 rainy days per month. Sunshine is abundant, averaging 7–8 hours daily, and sea temperatures remain ideal for swimming at 27–28°C. The hot season (March–May) brings higher temperatures (up to 35°C), increased humidity, and a gradual rise in rainfall. The rainy season (June–October) is marked by frequent but usually short-lived tropical downpours, especially in September and October, which are the wettest months (over 200 mm and up to 17–19 rainy days). Even during the wettest months, mornings are often sunny, and rain rarely lasts all day. Winds are generally light to moderate (12–18 km/h), with stronger breezes during storms. Annual precipitation averages 1,100–1,250 mm, and Pattaya enjoys around 2,000 hours of sunshine per year.
