Weather in September
Temperature
The beginning of September subtly marks a decrease in the average high-temperature, transitioning from a hot 86.5°F (30.3°C) in August to a warm 81.1°F (27.3°C). During the nights in September, the temperature averages to an enjoyable 63.5°F (17.5°C).Heat index
September's average heat index is appraised at a tropical 86°F (30°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
