Weather in July
Temperature
July, noted for its average high-temperature of 83.8°F (28.8°C) and an average low-temperature of 67.1°F (19.5°C), is considered the warmest month.Heat index
July's mean heat index is computed to be a very hot 95°F (35°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Heat index determinations are made taking into account the shade and light air movements. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
