Weather in July
Temperature
The warmest time of the year is July, with temperatures averaging a high of 93.7°F (34.3°C) and a low of 73°F (22.8°C).Heat index
July's average heat index is appraised at a blisteringly hot 109.4°F (43°C). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
