Severe Storms Hit Balearic Islands With Fallen Trees and Flooding After Heatwave

Severe storms swept across Mallorca and the surrounding Balearic Islands between Thursday, August 20, and Friday, August 21, 2026, following a period of extreme heat reaching 39 degrees Celsius. According to the island’s emergency response center, 112, emergency services registered a total of 109 incidents related to the severe weather across Mallorca, Menorca, Ibiza, and Formentera during a 20-hour window from 2:00 p.m. Thursday to 10:00 a.m. Friday.

Balearic Emergency Response and Regional Breakdown

The emergency dispatch data shows that the impact varied significantly across the island chain. According to regional reports, Menorca recorded the highest number of emergency calls with 48 incidents, while Mallorca logged 41. Ibiza registered 15 calls, and Formentera accounted for three.

Within Mallorca itself, municipal data indicates that Manacor experienced the heaviest concentration of weather-related problems with 11 reported incidents, closely followed by Felanitx with ten. Calvià and Sant Llorenç each recorded three cases. Across the entire archipelago, cleanup and repair efforts remained active on Friday morning, with 30 total incidents still unresolved as of 10:00 a.m., according to emergency officials.

Wind Gusts and Structural Damage

The state meteorological agency, AEMET, tracked the storm front as it moved across the islands on Thursday evening, hitting Ibiza around 9:00 p.m., reaching Mallorca near 11:00 p.m., and passing over Menorca by 1:00 a.m. Strong gale-force winds caused the vast majority of the damage rather than heavy rainfall.

According to weather station records, the strongest gust reached 99 kilometers per hour in Porreres. Other notable wind measurements included 95 kilometers per hour on the offshore island of Cabrera, 76 kilometers per hour in Son Servera, 75 kilometers per hour in both Manacor and the Llucmajor radar site, and 70 kilometers per hour in Port de Sóller.

Fallen trees formed the largest share of emergency interventions. Emergency crews cleared 28 trees that blocked roadways and another 21 that fell in parks, pedestrian zones, or private spaces. Additional weather hazards included 14 reports of fallen elements in public spaces, nine basic utility outages, nine reports of obstacles or spilled liquids on roads, and six warnings regarding precarious falling debris.

Maritime Incidents and Infrastructure Recovery

Coastal areas also sustained impacts from the turbulent waters and heavy winds. Emergency personnel secured six vessels that broke free or drifted at sea.

Municipal services responded to two structural floods inside buildings and commercial shops, alongside two motorcycle accidents linked to slick roads. Utility failures persisted into Friday morning, particularly in Sant Llorenç, where crews worked to restore interrupted basic services alongside ongoing repairs to downed trees and damaged public infrastructure.
