September weather forecastKalfou, Cameroon

Weather in September

September, the first month of the autumn in Kalfou, is still a tropical month, with an average temperature varying between 23.7°C (74.7°F) and 33°C (91.4°F).

Temperature

A minimal variation is noted in Kalfou's average high-temperature at the onset of September, reaching a still tropical 33°C (91.4°F) from August's 30.8°C (87.4°F). Throughout September, Kalfou experiences a low-temperature average of 23.7°C (74.7°F).

Heat index

The heat index value for September is computed to be a blisteringly hot 41°C (105.8°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

UV index

The months with the lowest UV index are January, July through September, November and December, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for average individuals.
Note: An average maximum UV index of 7 in September leads to these recommendations:
Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
