The island’s unique geographical location at the confluence of the Indian Ocean and the South Atlantic Ocean has a considerable impact on its climate, resulting in varying levels of sunshine throughout the year.
Sunlight dispersion globally plays a crucial role in determining the number of sunshine hours Mauritius receives in December. The sun’s rays strike the Earth at an angle, causing the light to spread out and decrease in intensity. This phenomenon affects the number of sunshine hours in different regions of the globe, with areas closer to the equator receiving more direct sunlight. Mauritius, being located near the Tropic of Capricorn, receives a significant amount of direct sunlight but with a reduced intensity due to the Earth’s spherical shape.
Times of Increased Cloud Cover in the Region
During December, Mauritius experiences a decrease in sunshine hours due to increased cloud cover. This is primarily caused by the southwesterly trade winds, which bring moisture-laden air from the Indian Ocean. As this air rises over the island, it cools, and the water vapor condenses, forming clouds. These clouds can block sunlight, resulting in reduced sunshine hours.
According to the Mauritius Meteorological Service, December is the wettest month in the country, with an average of 15 days of rainfall throughout the month. The increased cloud cover during this period can be attributed to the Intertropical Convergence Zone (ITCZ), a belt of low-pressure systems near the equator where winds from the northern and southern hemispheres converge. The ITCZ plays a significant role in shaping the weather patterns in the region, resulting in increased cloud cover and rainfall.
