Weather in July
Temperature
Oakton's temperatures peak on average in July, reaching 88°F (31.1°C) at their highest and 68.4°F (20.2°C) at their lowest.Heat index
In July, the heat index is calculated to be a torrid 100.4°F (38°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', offers an insight into how hot it feels when we factor in moisture content. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. 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.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
