In the coming days, residents of Spain will experience a series of abrupt weather changes affecting both the mainland and the islands. These shifts may impact daily routines, travel plans, and even people’s health, particularly those with chronic conditions.
According to RUSSPAIN.COM, by Wednesday, the west of Galicia will come under the influence of a humid front bringing rain and heavy clouds. Meanwhile, dense fog is expected in the morning along the Mediterranean coast and on the Islas Baleares, with lingering dust in the air that will reduce air quality and visibility. Despite these conditions, temperatures in most regions will remain above average for this time of year: in Cantabria and eastern Spain, thermometers will climb above 25 degrees.
Warmth and fog
On Thursday, the weather will stabilize, but fog and haze will persist in coastal and inland areas of the Mediterranean and the Balearic Islands. No precipitation is expected; however, dust masses will continue to affect western parts of the country, potentially causing discomfort for allergy sufferers. Temperatures will begin to rise in western Spain, while in the north they will slightly drop. Overall, the day will be noticeably warmer than usual for late March, with maximum readings exceeding the norm by 5–10 degrees.
Friday: Changing forecast
On Friday, meteorologists forecast another change in weather conditions. A new front will bring rain to the northwestern regions—Galicia, Asturias, and Cantabria. Brief showers are possible in neighboring areas. Inland territories, the Mediterranean coast, and the Balearic Islands will again experience morning fogs. Temperatures in the northwest will drop noticeably, especially in Galicia, Castilla y León, Asturias, and Cantabria. In central and eastern regions, maximum temperatures will remain between 20 and 25 degrees.
Saturday and Sunday: new surprises
On Saturday, precipitation is expected in the Cantabrian autonomous regions and in the area of Alto Ebro, with possible rain also in parts of Castilla y León, Navarra, La Rioja, and Aragón. Light rain may fall in the south of Valencia province and the north of Alicante. Temperatures in the north and east of the country will continue to decrease but will stay above average for late March. Minimum values will be close to normal.
On Sunday, the trend will shift: temperatures will start to drop in the south and rise in the north. Forecasts for this day remain uncertain, but the chance of precipitation persists across almost all of Spain, particularly in the Mediterranean regions, the south of Andalucía, as well as Ceuta and Melilla. Expected rain will be insignificant, but the following week may begin with unstable weather, cloudiness, and showers in the western and central areas, as well as along the eastern coast.
Canary Islands: Winds and Changes
On the Canary Islands (Islas Canarias), a strong north wind will start blowing on Wednesday, clearing the skies of the dust that has dominated in recent days. A noticeable drop in temperature is expected, returning to the usual March values. On Thursday, the wind will intensify, bringing prolonged rain to the north of the islands. On Friday, temperatures will rise slightly, but by the weekend they will fall again, with clouds and precipitation persisting on the northern slopes of the mountainous islands.
In recent years, Spain has faced weather anomalies more frequently: sudden temperature swings, unexpected downpours, and prolonged heat waves have become common across various regions. In 2025, a similar situation was observed in April when the north of the country experienced an abrupt cold spell after a week of unusual warmth, while Andalusia and the Balearic Islands recorded temperature highs. Last year, Galicia and Cantabria also experienced thick fog and heavy rain, causing transport disruptions and changes to flight schedules. These shifts in weather patterns require special attention to forecasts and readiness for sudden changes.
