Weather in July
Temperature
With average high temperatures of 89.1°F (31.7°C) and lows of 76.6°F (24.8°C), July is the warmest month.Heat index
Throughout July, the heat index is computed to be a blisteringly hot 107.6°F (42°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

A UV Index estimate of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for the ordinary person.Note: The daily high UV index of 7 during July translates into the following recommendations:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
