Weather in September
Temperature
September's presence marks an average high-temperature of a still hot 88.3°F (31.3°C), subtly varied from August's 90°F (32.2°C). Lillibridge observes an average low-temperature of 74.8°F (23.8°C) during September.Heat index
September's mean heat index is calculated to be a blisteringly hot 105.8°F (41°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
