Weather in July
Temperature
July, noted for its average high-temperature of 82.6°F (28.1°C) and an average low-temperature of 66.2°F (19°C), is considered the warmest month.Heat index
The heat index for July is evaluated at a tropical 91.4°F (33°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
