Weather in September
Temperature
September signals a slight drop in average high-temperature, sliding from August's 93.2°F (34°C) to a still hot 86.9°F (30.5°C). In Garlandville, September nights witness a steady temperature drop to a comfortable 65.7°F (18.7°C).Heat index
September's heat index is evaluated at a torrid 98.6°F (37°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
