Weather in July
Temperature
July, characterized by an average high temperature of 84.4°F (29.1°C) and a low temperature of 67.5°F (19.7°C), is generally the warmest month.Heat index
In July, the heat index is evaluated at a torrid 95°F (35°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Exercise precautions and adapt sun safety practices. Defence against skin and eye affliction is paramount. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
