Weather in July
Temperature
July, with average temperatures reaching a high of 84.7°F (29.3°C) and a low of 67.5°F (19.7°C), is the warmest month.Heat index
The heat index in July is estimated at a sweltering 96.8°F (36°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Heat index details are generally centered around shaded locations and a mild breeze. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. 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. Rising body temperatures due to excess heat retention could signify impending heat disorders.
