Weather in July
Temperature
Washington notes the warmest temperatures in July, with a high average of 85.8°F (29.9°C) and a low of 63.3°F (17.4°C).Heat index
For July, the heat index is computed to be a very hot 96.8°F (36°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
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 can be personal, changing with an individual's body mass, height, and level of physical exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
