Weather in August
Temperature
Deans marks the start of August with an average high-temperature of a still tropical 87.1°F (30.6°C), hinting at a slight fluctuation from July's 87.6°F (30.9°C). Nighttime temperature lowers to an average of 67.1°F (19.5°C) in August.Heat index
For August, the heat index is estimated at a torrid 102.2°F (39°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
