Chumphon,
Thailand, with temperature in the range of an average high of 34.5°C (94.1°F) and an average low of 24.5°C (76.1°F).
Temperature
With an average high-temperature of 34.5°C (94.1°F) and an average low-temperature of 24.5°C (76.1°F), April is the warmest month.
Heat index
The average heat index in April is evaluated at a blazing hot 53°C (127.4°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. With 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', 'feels like', 'apparent temperature', or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Additional factors like activity, clothing, pregnancy, and wind affect individual temperature impact. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it is vital to remain hydrated, particularly during prolonged physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
