Phuket in April: Songkran Festival, Hot Season & Shoulder Pricing
April in Phuket is a month of contrasts. It is the hottest month of the year — temperatures regularly hit 34-36°C with humidity that makes it feel closer to 40°C. The dry season is in its final stretch, with the first monsoon rains arriving late in the month. Most high-season crowds have departed, hotel prices have dropped to shoulder-season levels, and the island has a more relaxed, local feel. But April also brings Songkran — Thailand's famous water festival and New Year celebration (April 13-15) — which transforms Phuket into one of the most fun, chaotic, and thoroughly soaking destinations in the country. Bangla Road becomes a massive water fight, trucks with water tanks cruise the streets spraying everyone in sight, and the entire island embraces three days of celebration, traditional temple visits, and gleeful aquatic warfare. It is genuinely one of the most memorable festival experiences in Southeast Asia. For travellers who can handle the heat and want to experience Thai culture at its most joyful, April is an underrated month. The Similan Islands are in their final weeks of operation before closing for monsoon season, the seas are still calm for diving and island hopping, and you will pay significantly less than peak-season visitors while enjoying many of the same experiences. Just bring lots of sunscreen and stay hydrated.
Weather Overview
Temperature
26-36°C. The hottest month of the year, with daytime highs regularly reaching 34-36°C. Nighttime lows are 26-28°C. The heat index (factoring in humidity) can exceed 40-42°C during midday. Early mornings and late afternoons are much more comfortable.
Rainfall
130-160mm average — a transition month. The first two weeks are typically dry, with brief afternoon showers becoming more frequent in the second half of the month. By late April, some years see the first proper monsoon squalls. Overall, significantly drier than May-October but wetter than January-March.
Humidity
75-85%. Higher than the dry season peak months, contributing to the intense "feels like" temperature. The combination of high heat and high humidity makes midday outdoor activities demanding. Air conditioning and pool breaks become essential.
Sea
Generally good. The Andaman Sea is still calm in early-to-mid April, with visibility of 10-20 metres. By late April, conditions can become choppier as the monsoon approaches. The Similan Islands remain open through mid-April (closing around May 15). All west-coast beaches are typically green-flagged for swimming.
Pros & Cons
Pros
- Songkran Festival (April 13-15) — Thailand's most fun and unique celebration, with massive water fights, temple ceremonies, and island-wide festivities
- Shoulder-season pricing — hotel rates 20-40% lower than December-February peak, with much better availability
- Fewer crowds at beaches, restaurants, and popular attractions compared to high season
- Similan Islands still open for diving and snorkeling (through mid-May, but book early as operators begin reducing trips)
- Warm, mostly dry weather for the first half of the month — still very much beach weather
- The local, authentic vibe returns as peak-season charter tourism fades
- Excellent time for spa and wellness retreats — the heat makes pool and spa days especially appealing
- Last chance for high-season water clarity before monsoon season arrives
Cons
- Intense heat — 34-36°C with high humidity makes midday outdoor activities uncomfortable and potentially dangerous without precautions
- Heat exhaustion and sunburn risk is highest this month — hydration, sunscreen, and shade are essential
- Afternoon showers begin increasing in the second half of the month, previewing monsoon season
- Songkran dates (April 13-15) see a temporary surge in domestic tourism and pricing — the rest of April is quiet
- Some outdoor activities (jungle trekking, ATV tours) are best avoided during the hottest midday hours (11 AM-3 PM)
- The Similan Islands close in mid-to-late May, so April represents the final window — availability may be more limited
- The heat can make sleep difficult in budget accommodation without strong air conditioning
- Visibility underwater begins declining slightly as the monsoon approaches, compared to December-February peak
Events & Festivals
Songkran Festival / Thai New Year (13-15 April) — The highlight of the month and one of Thailand's biggest festivals. In Phuket, Bangla Road in Patong transforms into a massive water fight zone, with thousands of locals and tourists armed with water guns, buckets, and hoses. Trucks mounted with water tanks cruise the streets. Traditional elements include merit-making at temples, pouring water over Buddha images, and paying respects to elders. Soi Bangla is the epicentre, but water fights break out island-wide. Three days of celebration, with the actual Thai New Year falling on April 13.
Phuket Bike Week (mid-April, dates vary) — One of Southeast Asia's largest motorcycle rallies, attracting thousands of riders from across Asia. Live music, custom bike shows, group rides, and parties centred around Patong. Even if you're not a biker, the atmosphere and spectacle are worth experiencing.
Beach cleanup events — Several environmental organizations host beach cleanups across Phuket in April, timed before the monsoon season. Tourists are welcome to join and contribute.
Wan Lai Festival (after Songkran, usually April 14-15) — Phuket's local extension of Songkran celebrations, particularly in Saphan Hin and at various temples around the island.
Last Similan Islands trips of the season — Tour operators run final trips before the islands close for monsoon season, often with special pricing or extended itineraries.
