Weather in July
Temperature
July's onset records an average high-temperature of a still tropical 90.1°F (32.3°C), a near match to June's 88.3°F (31.3°C). High Island records an average nighttime low of 77.9°F (25.5°C) in July.Heat index
Throughout July, the heat index is evaluated at a blazing hot 113°F (45°C). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

A UV Index reading of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for the ordinary person.Note: The maximum UV index, 7 during July, leads to the following recommendations:
Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
