July weather forecast
Irvine, FL

July, the same as June, in Irvine, Florida, is another hot summer month, with an average temperature fluctuating between 90.1°F (32.3°C) and 74.5°F (23.6°C).

Temperature

The start of July marks an average high-temperature of a still tropical 90.1°F (32.3°C), hardly distinguishable from the conditions in June. During the month of July, the nighttime temperature falls to an average of 74.5°F (23.6°C).

Heat index

In July, the average heat index is computed to be a life-threatening hot 113°F (45°C). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. As body temperatures escalate without effective heat release, one might face dehydration threats.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Always opt for UVA and UVB-resistant sunglasses on radiant days.
