Weather in July
Temperature
July is the warmest month of the year, registering average temperatures as high as 91.8°F (33.2°C) and as low as 72.9°F (22.7°C).Heat index
For most parts of July, the heat index is calculated to be a blazing hot 118.4°F (48°C). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.Heat index determinations are made taking into account the shade and light air movements. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
