Weather in July
Temperature
July, noted for its average high-temperature of 88.7°F (31.5°C) and an average low-temperature of 65.8°F (18.8°C), is considered the warmest month.Heat index
The heat index for July is computed to be a fiery hot 102.2°F (39°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
