August weather forecast
Surat Thani, Thailand

August is a month where Surat Thani experiences a continuation of the rain-soaked monsoon season. Despite the weather remaining relatively the same as July, this month has its minor fluctuations. A slight increase in rainfall coincides with the drop in sea temperature, which remains steady at 29°C (84.2°F). These changes in weather do not affect the length of the day, which remains almost unchanged. However, the UV index stays persistent, warranting extra caution during sun-drenched days.

Temperature

The beginning of August records an average high-temperature of a still tropical 32.7°C (90.9°F), almost echoing the conditions of the previous month. Surat Thani's average low-temperature for the month of August records at a warm 23.4°C (74.1°F).

Heat index

August's heat index is computed to be a burning hot 48°C (118.4°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.
In terms of the heat index, values are set with light wind and shade conditions in mind. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Put into action all important safeguards, unprotected skin may burn swiftly. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation. Directly after outdoor activities or swimming, a broad-spectrum sunscreen with SPF 30+ should be applied generously and reapplied frequently. Be cautious! Sand and water surfaces make the Sun's UV rays more potent.
