Weather in August
Temperature
August is the warmest month, with the temperature often reaching an average high of 98.1°F (36.7°C) and an average low of 76.6°F (24.8°C).Heat index
For August, the heat index is estimated at a blazing hot 122°F (50°C). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are essentially critical for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Always opt for UVA and UVB-resistant sunglasses on radiant days.
