Weather in September
Temperature
The beginning of September brings a slight decrease in the average high-temperature, transitioning from a tropical 89.8°F (32.1°C) in August to a warm 83.1°F (28.4°C). The September nights bear witness to a significant drop from the daytime highs, settling at an average temperature of 61.2°F (16.2°C).Heat index
In September, the heat index is computed to be 82.4°F (28°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. 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.
