Weather in July
Temperature
Temperature readings reach their annual highs in July, averaging 89.2°F (31.8°C) and a minimum average of 68.7°F (20.4°C).Heat index
The heat index value during July is estimated at an extremely hot 105.8°F (41°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Fend off overexposure. Sun protection is vital. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
