Weather in July
Temperature
During the warmest month, July, temperatures average a high of 86.5°F (30.3°C) and a low of 69.4°F (20.8°C).Heat index
The heat index value for July is evaluated at a torrid 96.8°F (36°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. 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.
