Weather in August
Temperature
August reports an average high-temperature of a still warm 81.1°F (27.3°C), slightly varied from July's 84°F (28.9°C). An average nighttime temperature of 64.4°F (18°C) is witnessed throughout August.Heat index
Throughout August, the heat index is appraised at a hot 86°F (30°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.Heat index evaluations are typically in the context of light winds and shaded environments. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
