Yes, no problem with a wetsuit. If the day is warm you won’t have any issues with the water temperature. I was in Alcudia a month ago and swam there. Also, I am almost sure there is a municipal indoor pool.
Not Alcudia but swam at Port de Soller on the other side of the island 2 days ago - was fine with wetsuit - hands/feet not cold after 30min (and I suffer from cold hands/feet when <15 degrees or so). Enjoy!
fwiw i was swimming mornings at the beach in port de polencca and it was lovely. early i preferred wetsuit, later in the day without. lots of others swimming too
Yeah, I swam 3 weeks ago sans-wetsuit in that area (https://www.strava.com/activities/8807779095) - zero problems after 50 mins. Even went back out to get some photos/videos for another 20-30 mins.
I actually had brought my wetsuit, but given people were playing in the water with bikinis and less, it was a bit hard to justify throwing on the wetsuit.
Thanks everyone. Open water swim off the playa mura was absolutely fantastic. I wore a wetsuit and was very comfortable. I’d estimate around 20 Celsius. Possibly a bit too cool to swim for a long period without a wetsuit but definitely would be ok for shorter swims.
