Weather in July
Temperature
During the warmest month, July, temperatures average a high of 87.3°F (30.7°C) and a low of 68.7°F (20.4°C).Heat index
July's heat index is evaluated at a sweltering 98.6°F (37°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. As body temperatures escalate without effective heat release, one might face dehydration threats.

A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
