Arran Strong, 28, Presumed Dead After 4-Day Search Off Portugal Ends

Q: Did a rare genetic condition trigger the sudden, silent disappearance of this elite British surfer?

No evidence currently shows that Arran Strong’s rare genetic condition caused his disappearance. Strong had alpha-1 antitrypsin deficiency, a hereditary disorder that can increase the risk of lung and liver disease. That fact has been widely noted in tributes and background reports because it was part of his life story and made his elite surfing career especially remarkable. But neither Portuguese authorities nor GB Surfing have said the condition triggered the incident. What is known is limited. Strong vanished during a long-distance stand-up paddle crossing off Portugal’s southwest coast. His coach, José Maria Pyrrait, said he saw Strong’s board drifting roughly 100 meters away, but not the moment he went into the water. The area was deep, with poor visibility, and a major multi-agency search found no trace of him. Some reports have cited an unconfirmed suggestion that he may have suffered a medical episode. Others reported that he had forgotten his safety leash, which could have been critical because it meant he was not tethered to his board after becoming separated from it. Maritime officials also reportedly said sea and wind conditions were not unusually severe. Taken together, the available evidence does not support a firm link between alpha-1 antitrypsin deficiency and Strong’s disappearance. Until investigators or medical authorities provide verified findings, any claim that the genetic condition triggered a sudden, silent collapse remains speculation.

British surfer Arran Strong, 28, was presumed dead after Portuguese authorities halted a four-day search for him on Thursday, days after he disappeared about a mile off the coast.
Coach Jose Maria Pyrrait said the pair had stopped near Arrifana for water and photos on Monday; after Strong paddled ahead, Pyrrait later found only his board drifting roughly 100 meters away.
Pyrrait said he alerted shore contacts immediately, and a local fishing boat spent nearly 2 1/2 hours scanning the area with sonar before maritime authorities took over.
GB Surfing said Strong had represented Britain at the 2024 and 2025 ISA World Surf Games as its highest-placed male surfer, marking a major loss for the British surfing community.
