Weather in July
Temperature
July, with its average high-temperature of 86.5°F (30.3°C) and an average low-temperature of 68.9°F (20.5°C), holds the record as the warmest month.Heat index
For July, the heat index is calculated to be a sweltering 100.4°F (38°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
