Weather in July
Temperature
With average high temperatures of 86.5°F (30.3°C) and lows of 66.4°F (19.1°C), July is the warmest month.Heat index
Throughout July, the heat index is computed to be a sweltering 96.8°F (36°C). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

A UV Index reading of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for average individuals.Note: The maximum daily UV index of 6 during July translates into the following directions:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 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. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
