Temperatures climb to 32°C (89°F) but remain dry and comfortable. Crowds drop slightly from January's peak, making this arguably the best month for temple photography with soft morning light.

This is when Nong Khai shows its tropical colors - 36°C (97°F) highs with the year's lowest humidity make outdoor activities a test of endurance. Songkran festival brings celebrations but also the year's highest tourist crowds.
The monsoon arrives with 9.1 inches of rain, dropping temperatures slightly to 34°C (94°F) but raising humidity dramatically. Crowds thin considerably, and afternoon storms become the daily rhythm.
