Heat index

July's average heat index is computed to be a sweltering 39°C (102.2°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

UV index

April through November, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for the average person.
Note: In July, the average maximum UV index of 7 translates into the following recommendations:
Stay clear of intense sun exposure. Solar protection is of utmost significance. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
