Weather in July
Temperature
The warmest period tends to be July, when average temperatures fluctuate between a high of 87.3°F (30.7°C) and a low of 68.5°F (20.3°C).Heat index
In July, the heat index is estimated at a very hot 102.2°F (39°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
