A transition month, September introduces fall with moderately warm days and cool nights. Despite slight temperature dips from the summer months, Florida, Cuba's tropical vibe lingers. There's a notable rise in rainfall, signaling the start of the fall wet season. Longer nights make for cozy evenings, perfect for unwinding on a hammock or taking leisurely walks. September's weather offers a beautiful blend of summer warmth and autumn mildness, making it suitable for various activities.

Temperature

September observes an average high-temperature of a still tropical 31.9°C (89.4°F), marking an insignificant difference from August's 33°C (91.4°F). In the month of September, Florida's average low-temperature falls to a moderately hot 23.2°C (73.8°F).

Heat index

In September, the heat index is estimated at a blazing hot 45°C (113°F). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

The average relative humidity in September is 83%.
