Weather in September
Temperature
As September takes hold, the average high-temperature is a still hot 86.7°F (30.4°C), nearly mirroring that of the previous month. Edgewater Junction observes an average nighttime low-temperature of 75.9°F (24.4°C) during the month of September.Heat index
The heat index value for September is estimated at 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.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
