Weather in July
Temperature
With average temperatures fluctuating between a high of 88.3°F (31.3°C) and a low of 70.7°F (21.5°C), July stands out as the warmest month.Heat index
In July, the average heat index is evaluated at an extremely hot 104°F (40°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. 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 are particularly relevant to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
