Weather in July
Temperature
July, known for its average high temperature of 91.8°F (33.2°C) and an average low temperature of 70.3°F (21.3°C), is the warmest month.Heat index
The heat index in July is calculated to be a blisteringly hot 111.2°F (44°C). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. 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 essentially critical for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
