Weather in August
Temperature
August's beginning signals an average high-temperature of a still hot 88.2°F (31.2°C), barely different from July's 89.2°F (31.8°C). Harmon observes an average nighttime temperature of 67.6°F (19.8°C) during August.Heat index
Throughout August, the heat index is computed to be a torrid 100.4°F (38°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.Note that heat index values are valued for light wind and location in the shade. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for average individuals.Note: An average maximum UV index of 6 in August leads to these recommendations:
Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
