Weather in September
Temperature
With the arrival of September, McDade experiences a modest decline in average high-temperatures, transitioning from a fiery hot 96.8°F (36°C) in August to a tropical 88.9°F (31.6°C). In the month of September, the average temperature dips to an agreeable 70.9°F (21.6°C) during the night.Heat index
The heat index value during September is evaluated at a fiery hot 102.2°F (39°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.The standards for the heat index are set for locations in shade and under light breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical for babies and toddlers. 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.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. 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.
