Weather in July
Temperature
July, having an average high-temperature of 86°F (30°C) and an average low-temperature of 68°F (20°C), is the warmest month.Heat index
In July, the heat index is evaluated at a torrid 98.6°F (37°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.When referencing the heat index, its values are suitable for shady environments and light breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
