Weather in August
Temperature
Harriet's weather in August indicates an average high-temperature of a still hot 89.8°F (32.1°C), nearly consistent with the 90.5°F (32.5°C) of July. Harriet receives a consistent average low-temperature of 66.9°F (19.4°C) in August, a substantial dip from the day's heat.Heat index
August's average heat index is computed to be a blistering 107.6°F (42°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
