April in Thailand — events that affect travel
Known cultural, religious, or national events that surge prices, fill hotels, or close businesses during this month. Plan around them, or build your itinerary around the ones you'd like to see.
The world's biggest water fight — three days of street-wide water battles in every Thai city. Hotels in Bangkok and Chiang Mai book solid; offices and many shops close.

Crowds & pricing — April in Bangkok
Bangkok is in a shoulder season month — fewer crowds, slightly lower prices, and a calmer atmosphere than peak weeks.

Many regulars consider these months the best time to visit because you trade a small amount of weather reliability for a much more pleasant on-the-ground experience.
