Weather in August
Temperature
August reports an average high-temperature of a still hot 88°F (31.1°C), slightly varied from July's 88.7°F (31.5°C). An average low-temperature of 68.9°F (20.5°C) is common during the nights of August.Heat index
The average heat index in August is calculated to be a fiery hot 102.2°F (39°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. As body temperatures escalate without effective heat release, one might face dehydration threats.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
