Weather in August
Temperature
Wister's entry into August measures an average high-temperature of a still hot 92.5°F (33.6°C), closely parallel to the preceding month. Contrary to the day's heat, an average low-temperature of 69.4°F (20.8°C) is recorded during the nights in August.Heat index
In August, the average heat index is calculated to be a burning hot 113°F (45°C). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.When assessing, remember that heat index measurements are for light winds and shaded spots. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
