Weather in July
Temperature
The advent of July observes an average high-temperature of a still tropical 94.3°F (34.6°C), nearly identical to June's 90°F (32.2°C). Mertens records an average low-temperature of 74.8°F (23.8°C) throughout the month of July.Heat index
In July, the heat index is evaluated at a blazing hot 114.8°F (46°C). Be cautious: Heat exhaustion along with heat cramps are predicted. Heatstroke is a possible consequence of continuous physical effort.Remember that heat index calculations are made for conditions in the shade with light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for the average person.Note: A maximum high daily UV index of 7 during July translates into the following directions:
Prevent overexposure. Protection from the sun's harmful effects is needed. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
