Weather in July
Temperature
July, with its high-temperature average of 87.3°F (30.7°C) and a low-temperature average of 67.8°F (19.9°C), is the warmest month.Heat index
During July, the heat index is computed to be a torrid 102.2°F (39°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

Sunshine
The average sunshine in July is 10h.UV index
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 ordinary individuals.Note: The maximum UV index of 6 during July leads to these instructions:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
