Weather in September
Temperature
As August shifts into September, a minor alteration in temperatures is observed, with average highs reducing from a tropical 86.5°F (30.3°C) to a warm 81°F (27.2°C). An average nighttime temperature of 61.9°F (16.6°C) is recorded during September.Heat index
September's average heat index is evaluated at a tropical 86°F (30°C). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.For clarity, heat index numbers account for light winds and areas under shade. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', determines the feeling of heat when you account for the relative humidity. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to 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.
