Weather in August

The heat index for August is appraised at a very hot 96.8°F (36°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in 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 'apparent temperature' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. 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. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
