Weather in April

In April, Phuket endures its hottest month with temperatures scaling to 33.9°C (93°F). This increase coincides with a marked rise in the rainfall reaching 143mm (5.63"). The increase in precipitation levels contributes to a higher humidity index. Despite the uptick in rainfall, ample daylight hours and warm sea conditions allow beach activities to flourish. As April transitions to May, there are more rain-filled days but these conditions bring about a more vibrant natural environment.

Temperature

Phuket observes an average high-temperature of a still tropical 33.9°C (93°F) in April, barely different from 34°C (93.2°F) in March. Throughout April, the average low-temperature in Phuket dips to a moderately hot 25.8°C (78.4°F).

Heat index

In April, the heat index is estimated at a burning hot 49°C (120.2°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
When referencing the heat index, its values are suitable for shady environments and light breezes. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

UV index

Note: The daily high UV index of 12 in April translates into this advice:
Adopt all essential precautions. Preventing sun harm is crucial. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. One must apply and reapply generously an SPF 30+ broad-spectrum sunscreen every two hours or after an outdoor workout or swim. Heed this! UV intensity is much stronger when reflected off sand and water.
