Weather in July
Temperature
Saint Thomas's temperature records reveal July as the warmest month, marked by average highs of 90.1°F (32.3°C) and lows of 74.5°F (23.6°C).Heat index
July's average heat index is appraised at a life-threatening hot 113°F (45°C). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
