Arlington, TX

July is the epitome of summer in Arlington, with the highest average temperatures of the year. The city and its people resonate with the spirit of the season, participating in a plethora of sun-drenched activities. This time marks the year’s longest daylight hours, providing ample time for daytime endeavors. Despite high temperatures, a significant drop in relative humidity to 61% aids in reducing the feeling of stickiness. July’s wind speed drops further to 7.5mph (12.1km/h), offering gentle breezes, perfect for those summer night strolls.

Temperature

During July, Arlington records an average high-temperature of a still hot 94.6°F (34.8°C), marking a slight divergence from June's 90.9°F (32.7°C). Arlington experiences a consistent average temperature of 76.5°F (24.7°C) throughout the nights in July.

Heat index

Throughout July, the heat index is computed to be a life-threatening hot 113°F (45°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. 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 'feels like', arises from combining readings of air temperature and relative moisture content. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
