Weather in August
Temperature
August is the month that records the highest temperatures, with averages ranging from a high of 95°F (35°C) to a low of 73.6°F (23.1°C).Heat index
In August, the average heat index is computed to be an extremely hot 109.4°F (43°C). Mind: Heat cramps along with heat exhaustion are anticipated. Heatstroke can develop with continued physical activity.Heat index data is primarily for areas with shade and subjected to light winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. 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. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for the ordinary person.Note: In August, a daily UV index of 7 turns into the following recommendations:
Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
