Temperature
In August, Minamidaitōjima experiences a barely noticeable shift in meteorological conditions, with average high-temperatures moving from 31.2°C (88.2°F) in
July to a still tropical 30.9°C (87.6°F). An average low-temperature of 25.2°C (77.4°F) is expected during August.
Heat index
During August, the heat index is calculated to be an extremely hot 41°C (105.8°F). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.
Note that heat index values are valued for light wind and location in the shade. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
Humidity
The average relative humidity in August is 82%.
