Weather in August
Temperature
The highest temperatures are recorded in August, with averages reaching a high of 91.4°F (33°C) and a low of 72.5°F (22.5°C).Heat index
The heat index value for August is evaluated at a burning hot 114.8°F (46°C). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are quite important for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
