Weather in August
Temperature
Jefferson's weather in August indicates an average high-temperature of a still hot 92.1°F (33.4°C), nearly consistent with the 92.8°F (33.8°C) of July. Throughout the month of August, the nighttime temperature dips to an average of 72.3°F (22.4°C).Heat index
The heat index value during August is computed to be a burning hot 114.8°F (46°C). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.Be informed that the heat index values are oriented around shady conditions and gentle breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. 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 remain especially vital for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
