Weather in July
Temperature
July is the warmest month, exhibiting average temperatures of 91.4°F (33°C) at the peak and 71.8°F (22.1°C) at the base.Heat index
July's heat index is calculated to be a life-threatening hot 114.8°F (46°C). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.Remember that heat index calculations are made for conditions in the shade with light wind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Sunshine

June and July, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high threat to health from unsafe exposure to UV radiation for the ordinary person.Note: A maximum high UV index of 7 in July translates into the following recommendations:
Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Enhance your sun protection with tightly woven, yet airy clothing.
