Weather in July
Temperature
July tends to be the warmest month, with temperatures averaging a daily high of 90.9°F (32.7°C) and a low of 70.2°F (21.2°C).Heat index
For July, the heat index is appraised at an extremely hot 107.6°F (42°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.
