Weather in July
Temperature
July, with its high-temperature average of 91.8°F (33.2°C) and a low-temperature average of 70.7°F (21.5°C), is the warmest month.Heat index
In July, the heat index is estimated at a blisteringly hot 111.2°F (44°C). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
