What are the seasonal variations in rainfall across different regions of Mallorca?

Mallorca, the largest of the Balearic Islands, experiences significant seasonal variations in rainfall that can differ across its various regions. Generally, the island has a Mediterranean climate characterized by hot, dry summers and mild, wetter winters.

The western mountainous area, particularly around the Sierra de Tramuntana, receives the highest rainfall, averaging around 1,200 mm (47 inches) annually. This region often experiences increased precipitation during the autumn months, particularly between September and November, when storms are more common. In contrast, the central plains and southern coastal areas, including popular tourist destinations like Palma, tend to be drier, with average annual rainfall of about 400–600 mm (15–24 inches).

The summer months (June to August) are typically very dry across the island, while winter months (December to February) see more rainfall, with January often being the wettest month. Overall, the distribution of rainfall is influenced by the island’s topography, with the mountainous areas capturing more moisture from prevailing winds, leading to higher precipitation compared to the low-lying regions.
