Weather in September
Temperature
September is marked by a subtle drop in average high-temperatures, transitioning from a tropical 91.8°F (33.2°C) in August to a warm 84.7°F (29.3°C). During September, the nighttime temperature averages to a comfortable 64.4°F (18°C).Heat index
During September, the heat index is estimated at a hot 91.4°F (33°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.One should consider that heat index numbers are for shaded settings and light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
