Weather in July
Temperature
The warmest time of the year is July, with temperatures averaging a high of 87.4°F (30.8°C) and a low of 65.5°F (18.6°C).Heat index
July's mean heat index is computed to be a sweltering 102.2°F (39°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Sunshine

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 exposure to the Sun's UV rays for the average person.Note: The maximum daily UV index of 6 in July interprets into the following recommendations:
Resist overexposure. Safeguarding from solar damage is indispensable. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Enhance your sun protection with tightly woven, yet airy clothing.
