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.

Songkran (Thai New Year)
Festival · medium impact

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.

Plan: Bring waterproof phone bags. Either embrace the chaos or stay in a quiet beach resort that's out of the fray.

Crowds & pricing — April in Chiang Mai

Shoulder

Chiang Mai is in a shoulder season month — fewer crowds, slightly lower prices, and a calmer atmosphere than peak weeks. Most major sights stay open with normal hours, though a handful of seasonal restaurants or boat trips may run reduced schedules. 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.
