Weather in July
Temperature
July is the month when Decatur's temperatures reach their peak, with averages of 91.4°F (33°C) and lows of 71.4°F (21.9°C).Heat index
The heat index in July is computed to be a blazing hot 114.8°F (46°C). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.Heat index specifics point out values are for conditions of shade and a slight breeze. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
