Lanzarote Floods Costa Teguise – Storm Damage Facts Recovery Update
Severe flash flooding struck Costa Teguise and surrounding areas of Lanzarote on Saturday, April 12, 2025, as Storm Olivier delivered intense rainfall that overwhelmed drainage systems and submerged streets.

What Caused the Floods in Costa Teguise?
Storm Olivier and Meteorological Conditions
Storm Olivier generated a concentrated band of precipitation that stalled over Lanzarote’s eastern coast. Analysis of meteorological data showed the system developed rapidly, catching some residents by surprise despite the morning warning issued at 11:00 AM.
The Met Office Rainfall Radar would have shown intense red bands indicating extreme precipitation rates. The island’s typically arid infrastructure, designed for minimal annual rainfall, proved unable to channel such volumes effectively.
Costa Teguise received 62 liters per square meter in approximately two hours—equivalent to a year’s worth of rain in that brief timeframe. Tahiche recorded over 100 liters per square meter during the same afternoon period.
Infrastructure and Drainage Challenges
The volcanic terrain and urbanized surfaces of Costa Teguise prevent natural absorption of heavy rainfall. Drainage systems sized for moderate precipitation were overwhelmed within minutes, causing immediate sheet flooding that collected in low-lying areas including the Argana and Altavista neighborhoods.
What Damage and Casualties Resulted from the Floods?
Residential and Commercial Impact
The flooding inundated 95 homes and businesses in Arrecife alone, particularly affecting basements and garages throughout residential zones. Video footage captured cars floating and emergency teams struggling to secure drifting vehicles in Arrecife and Costa Teguise.
Hotels including the Selenus suffered significant water damage as basements flooded completely. Streets transformed into torrents that swept away vehicles and deposited debris throughout commercial districts, with water levels reaching dangerous heights in underpasses.
Authorities confirmed zero fatalities and no serious injuries resulted from the flooding, despite the extensive property damage and hazardous conditions encountered by residents and emergency responders.
Transportation Infrastructure
Major routes including the LZ-20 bridge to San Bartolomé and the Arrecife-Orzola road near Tahiche were closed completely. The HVA street in Altavista became impassable, while underpasses throughout the region remained submerged for hours after the rain ceased.
What is the Response and Current Status After the Floods?
Emergency Declarations
The Canary Islands government declared a state of emergency at 4:00 PM, activating the PECMAR emergency plan. Fifteen minutes later, the Lanzarote Cabildo declared an island-wide emergency, mobilizing additional resources for the affected municipalities and extending protocols through Sunday morning.
Rescue and Recovery Operations
The Emergency Consortium coordinated over 222 incidents through the 112 emergency service and civil protection networks. More than 100 personnel conducted round-the-clock cleanup operations in Arrecife and surrounding areas, with the sun’s return on Sunday facilitating restoration work.
Drivers should examine vehicles for water damage before operation. Check dashboard warning symbols for system malfunctions if cars were exposed to floodwaters, and avoid starting engines if water entered exhaust systems.
Current Safety Conditions
Power has been progressively restored to the approximately 3,000 residents who experienced outages. Arrecife Mayor Yonathan de León has formally requested “catastrophic zone” designation for affected areas to unlock financial aid for families and businesses.
While the initial emergency lifted at 7:00 AM Sunday, extended protocols remain active. Tourist areas are reopening, though visitors should avoid cordoned-off sections while safety inspections continue.
Is Costa Teguise Safe to Visit Post-Floods?
Costa Teguise is gradually returning to normal operations following the April 12 flooding, though recovery efforts remain visible throughout the resort. Hotels and businesses have reopened, with cleanup crews completing final debris removal from beaches and promenades.
Travelers should exercise standard precautions, avoiding any remaining cordoned areas near ravines or drainage channels. Protección Civil continues monitoring weather patterns, advising visitors to follow official updates regarding any renewed precipitation warnings.
