Is April Right for You?
Weigh the advantages and considerations before booking
Advantages
- + Songkran (Thai New Year) water festival April 13-15 turns entire cities into massive street parties with water fights and temple ceremonies. Expect chaos. Expect joy. Expect to get soaked.
- + Dry season continues in most mainland destinations. Perfect beach weather in southern Thailand and Vietnam's coast. Pack light. Pack sunscreen.
- + Prices drop significantly after Easter as shoulder season begins. Hotels and tours become more negotiable. Bargain hard. Save big.
- + Rice paddies in northern Vietnam and Laos turn electric green before harvest. Photographers' dream month. Bring extra memory cards.
- + Island hopping weather is ideal. Calm seas and clear skies for boat trips to Similan and Surin Islands. Jump in. Stay late.
Considerations
- − Temperatures can hit 35°C (95°F) with 70% humidity in Bangkok and Ho Chi Minh City. Outdoor sightseeing becomes exhausting by 11am. Start early. Seek shade.
- − Songkran means complete transportation chaos. Expect road closures, packed buses, and booked-solid accommodations in Thailand. Plan ahead. Walk more.
- − Burning season continues in northern Thailand and Laos through mid-April. Air quality can be poor with visibility reduced to 2 km (1.2 miles). Mask up. Check reports.
- − Popular islands like Phuket and Koh Samui start seeing pre-summer crowds as European Easter holidays overlap with local travel. Book beds. Arrive early.
Best Activities in April
Top things to do during your visit
Songkran Water Festival Tours
Experience Thailand's biggest celebration where entire cities become water fights. Chiang Mai's Old City hosts the most authentic version. Monks bless water at dawn, then streets turn into three-day water war. Bangkok's Silom Road becomes pedestrian-only with thousands armed with water guns. The cultural side happens at temples where Thais pour scented water over Buddha statues. Join both.
Booking Tip: Book accommodation 3-4 weeks ahead for April 13-15. Many hotels require minimum 3-night stays. See current tours in booking section below. Act fast.
Similan Islands Snorkeling
April is the sweet spot. Water clarity peaks at 30 m (98 ft) visibility before the monsoon season closes the islands in May. Manta rays and whale sharks are active, and you'll avoid the February crowds. The islands are 70 km (43 miles) offshore, so seas are calmer than rainy season. Dive in.
Booking Tip: Book 10-14 days ahead through licensed operators. Day trips run 8am-5pm, but overnight liveaboards give you dawn dives when whale sharks feed. Wake early. Worth it.
Mekong River Slow Boat Journeys
Water levels are good for the two-day slow boat from Huay Xai to Luang Prabang. The river runs high enough to avoid sandbanks but low enough for beaches to appear mid-river where boats stop for riverside BBQ lunches. Morning mist over the limestone karsts is pure Southeast Asia magic. Bring a camera.
Booking Tip: Book one day ahead in Huay Xai. No need for advance booking. Bring layers. Mornings on the river can be 18°C (64°F) before the sun burns off the mist.
Angkor Wat Sunrise Cycling Tours
April's sunrise hits at 5:47am. Early enough to beat the heat that peaks by 10am. Cycling the 6 km (3.7 mile) small circuit means you're moving in cooler air while bus tourists are still having breakfast. The rice fields around Angkor are neon green, and lotus ponds in front of temples are in full bloom. Pedal early.
Booking Tip: Start cycling at 5am, finish by 11am. Afternoon temple visits are brutal. Use that time for hotel pools or air-conditioned museums. Stay cool.
Ha Long Bay Overnight Cruises
April weather is textbook perfect. 26°C (79°F) days, minimal rain, and the limestone karsts emerge from morning mist like something from a watercolor painting. Fewer tour boats operate than peak season, so you get those Instagram-empty photos. Water is warm enough for swimming off the boat decks. Jump in.
Booking Tip: Book 5-7 days ahead. Choose boats that anchor in quieter Lan Ha Bay rather than main Ha Long. Same scenery, fewer crowds. See current cruise options in booking section.

April Events & Festivals
What's happening during your visit
April 13-15
Songkran Festival
Thailand's traditional New Year transforms cities into water fights while maintaining spiritual roots. Morning temple ceremonies with water blessing Buddha images give way to afternoon street water fights. Chiang Mai's moat becomes ground zero, Bangkok's Silom Road turns pedestrian, and even small towns have their own versions. It's impossible to stay dry. Embrace it.
Late March or Early April (check lunar calendar)
Bali Nyepi (Day of Silence)
Bali's Hindu New Year means complete silence. No flights, no traffic, no beach access, no electricity in many areas. Tourists must stay in hotels with blackout curtains. It's memorable. You can hear geckos and ocean waves without the usual scooter noise. Happens in March or April depending on lunar calendar. Surrender.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
Book onward travel during Songkran before you arrive. Transport sells out completely and prices triple. Plan ahead.
Northern Thailand burning season peaks early April. If air quality matters, skip Chiang Mai until after April 15. Breathe easy.
The real Songkran happens at dawn. Join locals at temples for water blessing ceremonies before tourist water fights start. Wake early. Feel blessed.
Island boat tours run reduced schedules after April 15 as operators prepare for monsoon season. Book early in the month. Sail sooner.
Lao and Cambodian visa-on-arrival lines get brutal in April heat. Apply online beforehand to skip 45-minute queues. Save sweat.
Avoid These Mistakes
Trying to stay dry during Songkran. Locals will soak you anyway, and it's considered rude to refuse. Accept fate.
Booking accommodation without air conditioning to save money. You'll need it when temperatures hit 35°C (95°F). Pay up. Sleep cool.
Planning temple visits for midday. Outdoor stone complexes become unbearable by 11am. Go early. Seek shade.
Assuming April is low season everywhere. Thai islands see European Easter crowds and domestic travel. Expect people.
