Weather in July
Temperature
The warmest period tends to be July, when average temperatures fluctuate between a high of 87.8°F (31°C) and a low of 69.1°F (20.6°C).Heat index
For July, the heat index is computed to be a fiery hot 102.2°F (39°C). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

May through August, with an average maximum UV index of 6, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for average individuals.Note: In July, the maximum UV index of 6 translates into these guidelines:
Prevent overexposure. Protection from the sun's harmful effects is needed. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
