Weather in August
Temperature
Olney's warmest month, August, registers temperatures that range from a high of 93.6°F (34.2°C) to a low of 71.2°F (21.8°C).Heat index
For most parts of August, the heat index is evaluated at a blazing hot 113°F (45°C). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.Keep in mind the heat index values are meant for areas in shade and with light wind. 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' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Enhance your sun protection with tightly woven, yet airy clothing.
