Weather in July
Temperature
Temperature records mark July as the warmest month, with highs averaging 91.6°F (33.1°C) and lows at 73.8°F (23.2°C).Heat index
During July, the heat index is computed to be a blisteringly hot 109.4°F (43°C). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.The heat index's values are generally associated with conditions in shade and light breezes. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. 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 extremely vital to babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV rays for the ordinary person.Note: The daily maximum UV index of 7 in July interprets into the following advice:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
