The Science Behind Lisbon’s Rainfall in December
Lisbon’s rainfall patterns in December are influenced by the city’s geographical location and its position in the path of moisture-rich air from the Atlantic Ocean. Portugal’s climate is generally classified as Mediterranean, with influences from both the oceanic and continental climate types. This blend of influences contributes to Lisbon’s unique rainfall patterns, which tend to peak in the winter months.
The primary cause of Lisbon’s rainfall in December is the presence of the Intertropical Convergence Zone (ITCZ), which brings warm, moist air from the equatorial region towards the Iberian Peninsula. This phenomenon is responsible for the majority of Portugal’s rainfall during the winter months, with the ITCZ’s influence peaking in December.
Regional Rainfall Patterns
The Azores High, a high-pressure system that dominates the North Atlantic, plays a crucial role in Lisbon’s rainfall patterns. As the Azores High moves eastward, it blocks the path of the westerly winds, leading to an increase in rainfall along the western coast of the Iberian Peninsula, including Lisbon. This phenomenon is commonly observed in December, resulting in increased rainfall along the western coast.
The city’s proximity to the Atlantic Ocean means that it is susceptible to the effects of coastal weather patterns. Lisbon’s rainfall is influenced by the onshore flow of moist air from the ocean, which brings warmth and moisture to the region. As this moist air rises, it cools and condenses, resulting in rainfall.
“The Azores High is a significant factor in determining Lisbon’s rainfall patterns in December.”
Monthly Rainfall Distribution
According to data from the Portuguese Institute of the Sea and Atmosphere (IPMA), December is one of the wettest months in Lisbon, with an average rainfall of around 122 mm. The majority of this rainfall occurs in the form of frontal systems, which bring heavy downpours and strong winds to the region.
| Day | Average Rainfall (mm) |
| — | — |
| 1-10 | 30-40 mm |
| 11-20 | 40-50 mm |
| 21-31 | 50-60 mm |
Conclusion
In conclusion, Lisbon’s weather in December offers a unique blend of rain and sunshine, making it an ideal time to explore the city’s festive atmosphere and attractions.
