Weather in July
Temperature
July is the warmest month of the year, registering average temperatures as high as 90.3°F (32.4°C) and as low as 73.6°F (23.1°C).Heat index
The heat index value for July is computed to be a blistering 111.2°F (44°C). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.Note that heat index values are valued for light wind and location in the shade. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
