Weather in July
Temperature
July's onset records an average high-temperature of a still tropical 91.2°F (32.9°C), a near match to June's 90.7°F (32.6°C). Throughout the month of July, Jamestown expects an average low of 72.3°F (22.4°C).Heat index
The heat index for July is calculated to be 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.Heat index data is primarily for areas with shade and subjected to light winds. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

A UV Index of 6 to 7 symbolizes a high health vulnerability from unprotected exposure to Sun's UV rays for the ordinary person.Note: In July, the maximum UV index of 7 transforms into these recommendations:
Deter overexposure. Protecting against the sun's effects is essential. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
