Weather in July
Temperature
July is the month when Fairfax experiences its warmest temperatures, averaging a high of 91°F (32.8°C) and a low of 73.4°F (23°C).Heat index
In July, the average heat index is evaluated at a blazing hot 113°F (45°C). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
