September weather forecast
Branford, FL

The first month of the autumn, September, is still a tropical month in Branford, Florida, with an average temperature ranging between max 87.3°F (30.7°C) and min 72°F (22.2°C).

Temperature

The transition into September is marked with an average high-temperature of a still tropical 87.3°F (30.7°C), showing an insignificant shift from August's 90.1°F (32.3°C). Throughout the month of September, Branford observes an average nighttime temperature of 72°F (22.2°C).

Heat index

Throughout September, the heat index is estimated at a very hot 102.2°F (39°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

The months with the highest humidity in Branford are August and September, with an average relative humidity of 78%.

Note: A daily high UV index of 6 in September leads to these guidelines:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
