Weather in August
Temperature
With its high average temperature of 95°F (35°C) and a low of 80.1°F (26.7°C), August is regarded as the warmest month.Heat index
August's mean heat index is evaluated at a blazing hot 118.4°F (48°C). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.Take note of the fact that heat index values are based on shaded circumstances with light airflows. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
