Weather in August
Temperature
Welcoming August, Tilden notes an average high-temperature of a moderately hot 85.5°F (29.7°C), nearly consistent with July's 87.3°F (30.7°C). During August nights, Tilden records an average temperature of 66°F (18.9°C).Heat index
For August, the heat index is appraised at a sweltering 96.8°F (36°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.In terms of the heat index, values are set with light wind and shade conditions in mind. Direct sunlight exposure may result in a rise of the heat index 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. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
