Weather in July
Temperature
July commences with an average high-temperature of a still hot 91.6°F (33.1°C), showing little deviation from June's 91°F (32.8°C). Throughout the nights in July, Harvey experiences an average low-temperature of 72.5°F (22.5°C).Heat index
Throughout July, the heat index is appraised at a blazing hot 116.6°F (47°C). Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 particularly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

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. Sun protection is enhanced with clothing that boasts a tight weave yet offers a loose fit.
