Weather in August
Temperature
August, having an average high-temperature of 87.6°F (30.9°C) and an average low-temperature of 80.6°F (27°C), is the warmest month.Heat index
The average heat index in August is calculated to be a torrid 100.4°F (38°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Sunshine

May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for the average person.Note: The UV index of 7 during August leads to these advisories:
Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Employ a wide-brim hat for potent defense against up to 50% of UV rays. Caution! Sand and water reflections can notably increase the UV radiation intensity.
