Weather in July
Temperature
July, noted for its average high-temperature of 85.6°F (29.8°C) and an average low-temperature of 65.1°F (18.4°C), is considered the warmest month.Heat index
Throughout July, the heat index is computed to be a very hot 96.8°F (36°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. 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. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
