Cheval, FL

The first month of the autumn, September, is still a hot month in Cheval, Florida, with an average temperature fluctuating between 74.8°F (23.8°C) and 88.7°F (31.5°C).

Temperature

At the start of September, Cheval's average high-temperature reaches a still hot 88.7°F (31.5°C), subtly different from the preceding month. Cheval, during September, witnesses an average low-temperature of 74.8°F (23.8°C).

Heat index

During September, the heat index is computed to be a blisteringly hot 105.8°F (41°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Humidity

September and December, with an average relative humidity of 76%, are the most humid months.

Rainfall

In Cheval, in September, during 20 rainfall days, 2.72" (69mm) of precipitation is typically accumulated. In Cheval, during the entire year, the rain falls for 162.9 days and collects up to 23.7" (602mm) of precipitation.

Note: In September, a daily maximum UV index of 7 leads to the following instructions:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
