February weather forecast and climate
Phuket, Thailand

February, the last month of the winter, in Phuket, is also a hot month, with temperature in the range of an average high of 33.6°C (92.5°F) and an average low of 24.9°C (76.8°F).
The ideal sea water temperature of 28°C (82.4°F) and only 3 rainfall days, with 23.9mm (0.94") of accumulated rainfall, makes February the best time for swimming and other water activities.

Temperature

In February, the average high-temperature in Phuket is practically the same as in January - a still hot 33.6°C (92.5°F). In Phuket, in February, the average low-temperature is 24.9°C (76.8°F).

Heat index

The average heat index is evaluated at a scorching 45°C (113°F). Be wary - heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Note that heat index values are valued for light wind and location in the shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature', 'feels like', 'felt air temperature', or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. This effect is subjective, depending on the activity and individual's heat perception influenced by various reasons (clothing, pregnancy, wind). Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If the body can not disperse the excessive heat and body temperature reaches conditions of hyperthermia, above 37.5°C (99.5°F) to 38.3°C (100.9°F), thermal conditions are potentially life-threatening.

Humidity

February is the least humid month, with an average relative humidity of 69%.

Rainfall

February is the month with the least rainfall. Rain falls for 3 days and accumulates 23.9mm (0.94") of precipitation.

Sea temperature

January, February and December, with an average sea temperature of 28°C (82.4°F), are months with the coldest seawater in Phuket.
Note: For swimming, diving, and other water activities, temperatures between 25°C (77°F) and 29°C (84.2°F) are perceived as very enjoyable and pleasurable for prolonged periods without feeling uncomfortable.

Daylight

The average length of the day in February is 11.9h.

Sunshine

The month with the most sunshine in Phuket, Thailand, is February, with an average of 9.7h of sunshine.

UV index

February through October, with an average maximum UV index of 12, are months with the highest UV index in Phuket. A UV Index estimate of 11, and higher, represents an excessive health risk from the exposure to the Sun's UV rays for the average person.
Note: The daily maximum UV index of 12 interpret into the following advice:
Practice all essential precautions. Protection against sun damage is crucial. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. A broad-spectrum sunscreen of SPF 30+ should be liberally applied and re-applied every two hours, and immediately after an outdoor workout or a swim. Caution! The reflection of sand and water significantly increases the intensity of the Sun's UV radiation.
