Hot days, warm nights and little relief from the humidity

April is among Phuket's warmest months, and the 79% humidity makes the heat an important part of planning your day. Keep active outings flexible, avoid putting your most demanding plans around midday, and choose somewhere with air conditioning if warm nights affect your sleep. Loose, lightweight clothes will be more useful than heavy layers, including in the evening. Temperatures reach 30°C on 38% of days, so the average should not be read as a ceiling. This suits travellers who enjoy sustained heat; if you prefer cool evenings after a warm day, April is likely to feel tiring rather than comfortable.

Plan for rain rather than uninterrupted sunshine

The catch is that April is wet, with sunshine averaging about 3.7 hours across 12.2 hours of daylight. That leaves plenty of daylight for being out, but it is not a promise of clear skies. Keep outdoor plans movable and pack a light waterproof or umbrella rather than relying on the heat to make rain irrelevant. The rainy-day figure does not tell you how long rain will last or when it will arrive, so do not assume a dependable dry slot each day. April works better for travellers happy to adapt than for those whose holiday depends on long, sunny days outside.
