Natural Heritage Area Trang, is another tropical month, with an average temperature ranging between min 24.4°C (75.9°F) and max 32.8°C (91°F).
Temperature
The transition from
April to May sees average high-temperatures adjusting to a still hot 32.8°C (91°F), from a not significantly different 31.7°C (89.1°F). Natural Heritage Area Trang witnesses a consistent average low-temperature of 24.4°C (75.9°F) throughout May.
Heat index
The heat index value during May is computed to be a burning hot 46°C (114.8°F).
Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
Consider that heat index readings are for situations in the shade and light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. 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 highly important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.

UV index
February through
October, with an average maximum UV index of 12, are months with the highest UV index. A UV Index estimate of 11, and higher, represents an excessive health risk from unprotected exposure to Sun's UV rays for the average person.
Note: In May, the maximum UV index of 12 translates into these guidelines:
Practice every essential safety step. People with fair skin could receive burns in fewer than 5 minutes. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. 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. Frequent application of a broad-spectrum SPF 30+ sunscreen is crucial, reapply it every two hours or immediately post swimming or outdoor exercise. Attention! UV radiation is markedly stronger with water and sand reflections.
