Weather in September
Temperature
September ushers in a minor alteration in Miami's climate, with the average high-temperature moving from August's tropical 88.2°F (31.2°C) to a warm 81.3°F (27.4°C). The nighttime temperature dips to an enjoyable 61.9°F (16.6°C) on average during September.Heat index
For most parts of September, the heat index is appraised at a hot 86°F (30°C). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.When referencing the heat index, its values are suitable for shady environments and light breezes. 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 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. 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 highly critical for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
