Weather in August
Temperature
The month of August sees the highest average temperatures, reaching 96.3°F (35.7°C) at the peak and 76.8°F (24.9°C) at the low.Heat index
For most parts of August, the heat index is computed to be an extremely hot 111.2°F (44°C). Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Sunshine
July and August, with an average of 11h of sunshine, are months with the most sunshine.UV index
May through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for average individuals.Note: In August, the maximum UV index of 7 suggests this advice:
Ward off overexposure. Defence against solar harm is crucial. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
