Weather in July
Temperature
The transition into July shows a subtle variation to a very hot 95.2°F (35.1°C) from June's 91.2°F (32.9°C) in the average high-temperature. July nights are marked by an average low-temperature of 76.6°F (24.8°C).Heat index
July's heat index is appraised at a burning hot 113°F (45°C). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.Heat index values are typically calculated for conditions of shade and a light breeze. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
