Parts of Mallorca have been placed on alert this Wednesday, 15 October, as a weather trough brings the risk of heavy rain and thunderstorms. María José Guerrero, the delegate and spokesperson for Spain’s State Meteorological Agency (Aemet) in the Balearic Islands, warned that further alerts are likely over the coming days in different areas of the island.
The south of Mallorca is under a yellow alert until 6pm, with rainfall expected to reach up to 15 litres per square metre in just one hour. Earlier in the day, warnings were issued for the north and northeast. Forecasters predict cloudy intervals with scattered showers across the island, with locally heavy downpours possible in the south during the afternoon, potentially accompanied by thunderstorms. Temperatures are expected to remain largely steady, ranging from 23°C to 27°C, slightly above the seasonal average of 23°C. Winds will be light to moderate from the north and northeast.
Looking ahead, Thursday is also expected to see unsettled conditions, particularly in the island’s interior and southern regions. Up to 20 litres of rain per square metre could fall in just one hour between noon and 6pm, with the heaviest rain expected around midday and early afternoon. Night-time temperatures may fall slightly, while daytime highs remain stable. Winds will continue light to moderate from the north and northeast, with weak coastal breezes in the south.
Friday is forecast to bring the most intense rainfall of the week. Yellow alerts are likely to be issued for the island’s interior, where up to 30 litres of rain could fall in an hour, and for southern areas, where up to 25 litres are expected. These warnings are set to be in force from noon to 6pm. By Saturday, the trough is expected to move on, with mostly clear skies and only occasional showers. Daytime temperatures are unlikely to change significantly, and winds will be light from the east, accompanied by gentle coastal breezes.
Guerrero noted that autumn is typically the wettest season in Mallorca, meaning further bouts of unsettled weather cannot be ruled out. Residents and visitors are urged to stay informed through Aemet forecasts and take precautions where necessary. The coming days are likely to see a mix of sunshine and showers, with isolated storms possible, particularly in southern and inland areas.
