Storm Deborah is set to cause a significant weather change in Mallorca, according to Aemet. The Balearics office spokesperson María José Guerrero has confirmed that this Tuesday and Wednesday will still feel spring-like, but a sharp turn towards winter conditions will occur by Thursday.
The weather forecast for today predicts mostly clear skies with a low chance of isolated light rain in the island's interior or south in the afternoon.
On Wednesday, 25 March, skies should remain mostly clear or slightly cloudy with some high clouds rolling in during the afternoon. Temperatures will hold steady or increase slightly, with highs ranging between 16°C and 21°C. Winds will be light to moderate from the southwest, shifting to a northern direction by the end of the day.
Storm Deborah brings winter back to Mallorca
Guerrero highlighted that by Thursday, 26 March, Mallorca will be affected by storm Deborah, marking a dramatic shift in weather. Skies will turn cloudy to overcast with scattered precipitation expected. The snowfall level will hover around 1,100 metres. Night-time temperatures will remain mostly unchanged, but daytime highs will drop notably, not exceeding 12°C to 15°C. Weak frosts may develop in the higher areas of the Serra de Tramuntana.
Winds will be light to moderate from the north. Additionally, Aemet’s Balearics branch has issued a yellow warning for rough seas along the Serra de Tramuntana’s northern and northeastern coasts, where waves could reach heights of three to four metres.
The following day, Friday, 27 March will continue to display winter-like conditions with cloudy skies and occasional showers, mainly during the morning. Snowfall altitude is expected to descend to around 900 metres. Temperatures will stay largely unchanged, with maximums between 13°C and 16°C, and frost likely persisting in the Serra de Tramuntana. Winds will be moderate northerly, easing to light.
Looking ahead, Guerrero mentioned that meteorological instability is anticipated to persist into Saturday, 28 March, although rain will be less probable. Temperatures will remain below typical seasonal averages, with highs again between 13°C and 16°C. A further cold front is forecast for Sunday, which will bring an additional drop in temperatures and lower snow levels.
