Weather in August
Temperature
The commencement of August introduces an average high-temperature of a still hot 87.1°F (30.6°C), closely mirroring the preceding month. An average low-temperature of 65.7°F (18.7°C) is recorded in the month of August.Heat index
The heat index in August is evaluated at a very hot 100.4°F (38°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Data suggests that the heat index is set for environments in shade and with a light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
