Weather in July
Temperature
The highest temperatures are recorded in July, with averages reaching a high of 90.5°F (32.5°C) and a low of 73.2°F (22.9°C).Heat index
July's average heat index is appraised at an extremely hot 111.2°F (44°C). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
