Weather in August
Temperature
Sursaut's average high-temperature in August is a tropical 30.4°C (86.7°F), marking an insignificant difference from the 29.5°C (85.1°F) of July. In Sursaut, an average temperature of 24.5°C (76.1°F) is noted during August nights.Heat index
August's mean heat index is estimated at a very hot 38°C (100.4°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Deter overexposure. Protecting against the sun's effects is essential. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
