Weather in July
Temperature
The months of July and August bring the highest temperatures, averaging a high of 89.8°F (32.1°C).Heat index
July's average heat index is computed to be a blistering 109.4°F (43°C). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. 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 are especially vital to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days. Take warning! Reflective sand and water surfaces intensify the Sun's UV rays.
