Thailand weather

Although regions influence much of Thailand’s weather, the country has a tropical monsoonal climate with three distinct seasons: the dry, cool season from November through February where high temperatures range from 30-35°C; the hot season from March through June where 40°C temperatures are not uncommon; the rainy season from July through October when downpours and torrential rains that bring lower temperatures are common particularly the last three months.
