December weather forecast
San-Pedro, Ivory Coast

By December, the heat intensifies further with temperatures reaching a peak of 30.5°C (86.9°F). Despite being the ultimate month of the year, it does not deviate much from the November heat patterns. The sea temperatures rise higher, making the city more humid. A marked reduction in rainfall makes for drier weather conditions. As a result, cloud cover reduces significantly as compared to November, slowly bringing the city back to its dry and hot state, similar to the beginning of the year.

Temperature

The arrival of December sees an average high-temperature of a tropical 30.5°C (86.9°F), hardly diverging from November's 29.5°C (85.1°F). Nighttime temperature lowers to an average of 24.5°C (76.1°F) in December.

Heat index

December's average heat index is computed to be a sweltering 39°C (102.2°F). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.
Heat index determinations are made taking into account the shade and light air movements. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

In December, the average relative humidity is 78%.

Stick with precautions and abide by sun safety procedures. Evading sunburn is essential. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Attention! UV radiation is ramped up when reflecting off sand and water surfaces.
