September weather forecast
Futa, Sierra Leone

September, the first month of the autumn in Futa, is still a warm month, with an average temperature ranging between min 21.5°C (70.7°F) and max 28.4°C (83.1°F).

Temperature

With the onset of September, the average high-temperature registers at a still moderately hot 28.4°C (83.1°F), subtly different from August's 27°C (80.6°F). Futa, in the month of September, anticipates a consistent average low-temperature of 21.5°C (70.7°F).

Heat index

September's heat index is evaluated at a torrid 35°C (95°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Humidity

The average relative humidity in September is 92%.

UV index

The average daily maximum UV index in September is 6. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for average individuals.
Note: A typical high UV index of 6 in September suggests the following recommendations:
Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
