Weather in Siller Las Palmeras

Climate in Síller (Las Palmeras) — Sun and Dry Conditions in the Southwest

Síller (Las Palmeras) sits in the southwest of Mallorca, in the municipality of Calvià, just above sea level. This location shapes the climate in a very direct way: the area opens toward the sea, has no mountain ridge behind it to trap rainfall, and at the same time benefits from the thermal stability of the coast. The result is a classic Mediterranean climate with hot, dry summers and mild, occasionally rainy winters.

Rainfall follows the pattern typical of the Bahia de Palma: most precipitation falls in autumn and winter. AEMET records 449 mm of annual rainfall for Palma — a reference figure that offers useful orientation for the entire bay. November is statistically the wettest month, with approximately 79 mm for the region according to aggregator climate data. These rains often arrive as intense events rather than prolonged, steady showers.

Residents and visitors experience summer in Síller as hot and sunny. Daily highs in July reach around 31°C according to aggregator climate data, with a daily average of around 26°C. Dryness is pronounced during this season: July sees an average of just around 9 mm of rain. Worth noting is that the southwest coast can be more frequently affected than other parts of the island by Calima conditions in the summer months — hot Saharan dust that clouds the air and raises the perceived temperature. Reliable frequency figures are not available for this article, so specific claims on this point are not made.

Autumn brings the sea temperature into focus: in October the water releases stored summer warmth at around 23°C, while onshore air temperatures have already cooled to a daily average of around 20°C. This combination makes September and October climatically appealing for coastal stays — less heat, warm water.

Winter is mild. In January the daily average sits at around 11°C — cool, but frost-free under normal conditions. The coastal position prevents extreme cold-air intrusions. Those looking to experience Mallorca away from the summer crowds will find quiet conditions in the Calvià region from October through April, though warmer clothing is advisable for trips inland and into the Tramuntana.

Note on data sources: Síller (Las Palmeras) has no dedicated AEMET climate-normal station. The monthly figures in this article are approximations based on Palma aggregator data (T3 source, klimatabelle.info). AEMET station B228 Palma serves as the official reference benchmark (T1).
