May weather forecast and climate
Chumphon, Thailand

The last month of the spring, May, is another tropical month in Chumphon, Thailand, with average temperature varying between 33.3°C (91.9°F) and 24.7°C (76.5°F).

Temperature

In May, the average high-temperature is essentially the same as in April - a still hot 33.3°C (91.9°F). In Chumphon, Thailand, the average low-temperature is 24.7°C (76.5°F).

Heat index

The average heat index is calculated to a life-threatening hot 50.4°C (122.7°F). Beware - heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
Note that heat index values are valued for light wind and location in the shade. With the exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature', 'apparent temperature', 'real feel', or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Additional factors like clothing, wind, differences in body mass, height, and shape, and activity influence one's weather impression. 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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
