Weather in September
Temperature
Onward observes a minor difference in average high-temperatures between August's 90.5°F (32.5°C) and September's 86.9°F (30.5°C). During September, the nighttime temperature averages to a comfortable 67.6°F (19.8°C).Heat index
Throughout September, the heat index is appraised at a sweltering 98.6°F (37°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. When directly under the sun, the weather's impact can intensify, possibly boosting 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.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. 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. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
