Weather in July
Temperature
The onset of July marks an average high-temperature of a still moderately hot 83.5°F (28.6°C), hardly differing from June's 82.9°F (28.3°C). In Frederiksted, July's low temperatures hover around a still warm 81.7°F (27.6°C), reflecting a minor decrease from the daytime highs.Heat index
In July, the heat index is calculated to be a tropical 91.4°F (33°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
