Satun continues its journey through the wet season in
May with a pronounced leap in rainfall, marking the peak in precipitation for the year. Additionally, amplified humidity amplifies the sensation of heat, despite temperatures slightly falling from
April's readings. This month is a melting pot of climatic extremities and, consequently, carries an unforgettable signature. Among the most notable of May's weather traits is the rainfall peak of 233mm (9.17"), reinforcing its title as one of the climatic cornerstones of Satun's monsoon landscape.
Temperature
During May, Satun records an average high-temperature of a still tropical 33°C (91.4°F), marking a slight divergence from April's 34.1°C (93.4°F). May brings an average low-temperature of 24.5°C (76.1°F) to Satun.
Heat index
The heat index in May is evaluated at a blazing hot 49°C (120.2°F).
Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.
Note that heat index values are valued for light wind and location in the shade. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
