December weather forecast
Kirima, Sierra Leone

December, the first month of the winter in Kirima, is still a hot month, with an average temperature varying between 31°C (87.8°F) and 24.5°C (76.1°F).

Temperature

The dawn of December sees an average high-temperature of a still tropical 31°C (87.8°F), subtly contrasting with November's 30.1°C (86.2°F). The temperature lowers to an average of 24.5°C (76.1°F) during December nights.

Heat index

December's average heat index is evaluated at a fiery hot 37°C (98.6°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Humidity

In December, the average relative humidity is 69%.

Rainfall

In Kirima, during December, the rain falls for 4 days and regularly aggregates up to 7mm (0.28") of precipitation. Throughout the year, there are 205.9 rainfall days, and 1507mm (59.33") of precipitation is accumulated.

UV index

The months with the highest UV index are January through June, September through December, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for average individuals.
Note: In December, the average maximum UV index of 7 translates into the following recommendations:
Deflect overexposure. Sun protection is a necessity. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
