Weather in August
Temperature
August stands out as Kemah's warmest month, with an average high-temperature of 90.5°F (32.5°C) and a low-temperature of 79.7°F (26.5°C).Heat index
August's average heat index is computed to be a scorching 109.4°F (43°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Resist overexposure. Safeguarding from solar damage is indispensable. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck. Attention! The reflection of both water and sand can increase the intensity of UV rays.
