Ibiza Airport Flooded as Storm Adam Broke a 2005 Record

Ibiza airport closed twice on 18 October after Storm Adam put a record 173.8 mm of rain on the airfield and forced 16 diversions. Airport operator Aena later counted 27 cancellations that Sunday. Water came through the terminal roof, a car-park canopy came down, and inbound jets from Manchester, Newcastle and London Stansted never landed.

By 20 October Aena reported no delays, cancellations or diversions at Balearic airports. The rain that killed four people fell on the Valencia and Alicante coast, where Aemet logged more than 600 mm in places. Ibiza had a flooded runway, a record at its own weather station, and a two-day mess for anyone trying to arrive.

Two Halt Windows, Then a Day of Diversions

Aena said it stopped all traffic from 10:00 to 11:00 on Sunday for safety in the heaviest rain, then stopped it again from 11:15 to 12:15 while crews pumped water off the airfield. That is two hours of halt with a 15-minute gap in between, when they tried to restart and could not. Spain’s air traffic controllers posted that the airport was not operational and that they were sending inbound aircraft to other fields in bulk.

The first official tally, covering those two windows, was 16 diversions and five cancellations. By 19:00, cancellations at Ibiza had climbed to 27. The diversion count stayed at 16. Aena’s flight list at the time named inbound services from Bristol, Eindhoven, Madrid, Brussels and Berlin among the jets that went elsewhere, and a London departure that was cancelled. Local flight-tracking logs also listed Manchester, Newcastle and London Stansted in the inbound wave that never arrived.

Those UK and Dutch routes sit inside the 23 airlines operating at Ibiza Airport, a winter-shoulder mix that still includes Ryanair, easyJet, Jet2, Vueling and TUI. A share of Sunday’s stranded cabins were people starting a holiday, not leaving one. They spent the day at some other Spanish airport, with the island still in front of them.

SUNDAY AT IBIZA AIRPORT

1. 6:00 to 12:00: The airport weather station takes 103.5 mm, the core of the day’s rain.
2. 9:15: The first inbound diversion is logged as water sits on the runway.
3. 10:00 to 11:00: Aena halts operations for safety.
4. 11:15 to 12:15: A second halt while crews pump the airfield; the last diversion is logged at 12:00.
5. 11:21: An ES-Alert hits phones on Ibiza and Formentera, telling people to stay off flooded roads.
6. 13:17: Flight-tracking data shows 53 delays, an 84-minute average wait, and 15 cancellations against 288 planned operations (148 arrivals, 140 departures).
7. 19:00: Aena’s day tally is 27 cancellations and 16 diversions.

The runway was not the only wet surface. Aena said the storm hit parts of the terminal and the outside of the building. Access to car park P1 was shut after a canopy collapsed, and one of the two Express car-park lanes went out of use. P1 had reopened by evening, with one Express entrance still working. The island council closed the airport road in both directions near Platja d’en Bossa. Rain rarely grounds an airliner on its own. Water pooling on the pavement does, because braking grip collapses, which is why Ibiza stopped landings and sent crews out with pumps.

173.8 mm Broke a Record Set in 2005

Spain’s State Meteorological Agency, Aemet, confirmed the airport station recorded 173.8 mm in 24 hours, the highest total there since measurements began in 1944. The previous mark was 156.5 mm on 17 September 2005. The new figure is 17.3 mm higher, about 11 percent above a record that had stood for 21 years.

That 24-hour burst landed on an island whose typical October total of 58 mm is the whole month, not a single morning. In other words, the airport took about three times a normal October in one observation window. Aemet’s later weekly roundup, covering 14 to 20 October, put 234 mm at the Ibiza observatory, Es Codolà, and said totals topped 200 mm on the island.

The daily table is a different cut of the same storm. Calendar Sunday at the airport was 123.5 mm. Calendar Monday was 75.9 mm. Added together that is 199.4 mm in two days, the largest official two-day haul among Aemet’s five Pitiusas stations.

RAIN AT IBIZA AND FORMENTERA STATIONS

Most of Sunday’s water fell between 6:00 and 12:00, the same window as the runway closures. Formentera took 113.2 mm in those six hours, 91 percent of its official Sunday total. After noon, no official station on either island topped 13 mm through the afternoon. Ibiza city then had a wetter Monday than Sunday, 83.4 mm against 68.4 mm. Wind was a sideshow: gusts hit 63 km/h at the airport on both days, and 67 km/h on Formentera at 4:20 on Monday.

Palma Took the Heavier Cancellation Load

Mallorca’s airport cancelled more flights than Ibiza on Sunday. Aena reported 37 cancellations at Palma de Mallorca, plus widespread delays as weather flow limits held aircraft on the ground. Ibiza’s problem was a flooded field and a closed terminal access. Palma’s was volume: it is the islands’ main hub, so a bad morning there backs up the whole Balearic schedule.

AENA CANCELLATION COUNTS

Monday was quieter at Ibiza and still ugly at Palma. By 16:00, Aena had five more Ibiza cancellations, three of them to Palma and two to Alicante, plus one diversion. Palma by then had 10 cancellations and 12 diversions. Menorca lost a Palma flight the same day. Schools on Ibiza and Formentera stayed shut on Monday. Controllers had already warned on Sunday that a return to the timetable would take a long time, because each diverted aircraft and crew finishes the day in the wrong city.

What Are You Owed After a Weather Cancellation?

A cancelled EU flight still gives you a choice. The European Commission’s Your Europe guide says passengers get a refund, rerouting or a return flight, plus help at the airport. A hotel is included if you are rebooked the next day. Meals and two free communications sit in the same care package.

Cash is the piece that drops away. The same guide treats severe weather as an extraordinary circumstance. If the airline can show Storm Adam caused the cancellation, the fixed €250, €400 or €600 payment is not due. That is the rule that will still annoy people after the floor is dry, because a two-hour pump-out at a single-airport island can strand a family overnight without ever becoming the airline’s “fault” on paper.

WHAT THE AIRLINE STILL OWES YOU

• A choice: Refund of the unused ticket, a reroute at the earliest chance, or a later flight that suits you.
• Care while you wait: Meals and drinks in line with the delay, plus two free calls, texts or emails.
• A bed if you miss the day: Hotel and transfers when the next flight is the following morning.
• No cash, if weather is proved: The €250 to €600 compensation does not apply when the carrier shows the storm made the flight impossible.

Keep every receipt if you bought food, a taxi or a room because nobody from the airline was there to arrange it. File those costs with the carrier. The care duty does not vanish just because the rain does.

Four Deaths, All of Them Off the Island

Aemet named the system Adam, an isolated upper-level low of the kind Spain calls a DANA, and issued Special Notice 37/2026 on 18 October forecasting 300 to 400 mm over the full episode along the southern Valencia coast and around Cape La Nao. Pego in Alicante received 632 mm in 36 hours, with 465.2 mm on 19 October alone. Those mainland totals sit in a different league from Ibiza’s record.

THE MAINLAND TOLL

• Four flood deaths: A 35-year-old woman swept into the Cabrera de Mar stream on 17 October, her body found near Premià de Mar; a woman who entered the sea at Sagunto; a 79-year-old woman found on the ground floor of her home in Oliva; a 64-year-old man who had a heart attack at a flooded campsite in the same town.
• 145 municipalities: Valencia’s government confined southern Valencia and northern Alicante, then lifted the last of those orders on the evening of 19 October.
• 2,141 evacuations: The Guardia Civil also logged 496 rescues, 423 of them in Valencia province and 73 in Alicante.
• 1,876 emergency calls: The 112 centre counted 1,259 incidents in Valencia, 595 in Alicante and 22 in Castellón from 17 October to the morning of 20 October.

Ibiza and Formentera were not untouched. By noon on Sunday, 112 had 61 incidents on the two islands, 38 of them on Formentera and 23 on Ibiza. Firefighters later logged dozens of flood callouts. The Military Emergency Unit pumped water and cleared debris. Nobody on the islands is in the death toll. The photographs of water in the Ibiza terminal travelled as the tourist image of the storm. The 632 mm at Pego is the figure that belongs with the funerals.

Aena Logged a Clean Sheet on Tuesday

On 20 October Aena reported no flight delays, cancellations or diversions across the Balearic airports. Spain’s traffic directorate said the island road problems, including the Ibiza airport approach, were cleared the same day. Classes on Ibiza and Formentera resumed that Tuesday. Palma’s beach weather was already being sold as sunshine above 20°C once the yellow warning timed out.

The UK Foreign Office did not add a Storm Adam line to its foreign travel advice for Spain. That page was still current on 23 October, with its last update dated 12 August 2026, on nitrous oxide fines and Gibraltar traffic. The standing note on flash flooding, check Aemet and follow local officials, never became a warning against travel. The U.S. State Department did post a short alert on 19 October about coastal flooding, movement limits and ES-Alert messages.

If you still hold a ticket, the useful check is the airline app, not a weather map from last Sunday. The airfield that set an 82-year rainfall record was back on the timetable two days later. The people who never landed on the 18th are the ones still owed a reroute, a refund, or a receipt.

Frequently Asked Questions

How Much Rain Fell at Ibiza Airport During Storm Adam?

The 173.8 mm record is a rolling 24-hour observation from 9:00 on 18 October to 9:00 on 19 October, not a calendar day. Aemet’s daily table split the same storm into 123.5 mm on Sunday and 75.9 mm on Monday. A volunteer station at Can Xumeu on Formentera, run by collaborator Vicenç Roig Torres, reported 203.5 mm in 24 hours, higher than any official Pitiusas gauge, and it sits outside the airport series.

Did Ibiza Airport Shut Completely?

Aena halted traffic twice and restored it after the second pump-out, so the field was not closed all day. Flight-tracking counts used by local reporters logged 17 inbound diversions between 9:15 and 12:00, one more than Aena’s 16 for the official halt window, because the first go-arounds began before 10:00. After midday, the airport ran at a reduced rate against a 288-operation plan.

Can I Get Cash Compensation for a Storm Adam Cancellation?

Not the €250 to €600 cash, if the airline shows the storm made the flight impossible. You still get a refund of the unused ticket within seven days if you pick that option instead of a reroute. Passengers dumped at a different airport are owed transport to their original destination, or back to where they started, at no extra cost, and that duty sits beside the meals-and-hotel rules rather than instead of them.

When Did Flights Return to Normal at Ibiza and Palma?

Aena’s first day with no delays, cancellations or diversions was 20 October. The airport access road near Platja d’en Bossa was shut on Sunday and still cut between kilometre 3 and kilometre 5.5 on Monday morning, which is why Aena asked drivers to take extra care even after the runway reopened. Spain’s traffic directorate said all affected island roads were clear on Tuesday, the same morning schools restarted on Ibiza and Formentera.

The airfield that measured 173.8 mm was back on a normal Tuesday timetable. The people who spent Sunday in a departure lounge in Manchester, or on a taxiway in Alicante, are the leftover of a two-hour closure that had nowhere else to send an island arrival.
