Find the right person to share the lineup with.

Finding a good wave in Portugal is the easy part. Finding someone to surf it with, who’s at your level and free when you are, not that easy. Most surfers we know end up going alone more than they'd like.

This is our attempt to fix that.

Maybe you just moved here. Maybe no one in your circle surfs. Or they do, but not at your level.

Going alone is fine sometimes. But it’s different when there’s someone to text when the forecast looks good. Someone who pushes you to paddle for waves you’d normally let go.

Every month, we introduce you to a new surfer. Some people become your regular surf partner. Others you’ll surf with a few times. Either way, your surf crew grows.

Currently connecting surfers across Portugal, more locations coming.

How it works

Three steps

01

Tell us how you surf

A short questionnaire. Your level, your spots, when you're usually in the water, what you're after. Takes about three minutes, you can fill it in here.

02

We find your match

Once a month, we go through everyone in the community and make a considered match. When we find a good fit, we introduce you both by email.

03

Go surf together

The rest is up to you. All you have to do is connect, check Surfline and head out there.

The matching

What we look at & why it matters

We look at surf level, your regular spots, when you tend to surf, and how often. The more overlap there is between two people, the better the match. It doesn't always line up perfectly, but we find the best fit we can.


01

Someone at your level

Surfing with someone significantly better or worse than you changes the dynamic of a session in ways that rarely work out well for either person. We match on level first, everything else second.


02

Same spots

We match on the same home breaks. No point connecting two people who live two hours apart and would never actually meet up.


03

When you surf

Dawn patrol or weekend afternoons - we match on when you’re usually in the water so there’s a reasonable chance you’re both free at the same time.


We're currently matching surfers across Portugal: Lisbon, Ericeira, Peniche, the Alentejo coast, Porto and beyond. Not seeing your area? Sign up anyway. You'll be first in line when we get there.

  • Carcavelos, Guincho, Costa da Caparica, Foz do Lizandro, Praia do Sul, Ribeira d'Ilhas, São Julião, Baleal, Peniche, Porto Covo, Sines, São Torpes, Vila Nova de Milfontes, Matosinhos, Espinho, Esmoriz, Arrifana, Sagres.

A few other things worth knowing

  • While we’re running this beta version, Twin Fin is completely free. No card required, no hidden tiers. We'll be upfront when that changes, and beta members will get first access to any early-member pricing.

  • We only share your details with your confirmed match, when we introduce you both. We don’t use it for marketing. Ever.

  • Everyone on Twin Fin signed up for the same reason: to find more people to surf with.

    Like any first session, you’ll probably exchange a few messages beforehand and take it from there. We’d suggest meeting at a popular break the first time. If you ever have any concerns, we're always reachable at hello@twinfinsocial.com.

  • Yes. If you'd prefer to be matched with someone of the same gender, you can select this in the sign-up form and we'll always respect it.

  • We're growing, which means some areas have more members than others. Matches depend on who’s nearby. If we can't find a good fit for you yet, you'll be first in line as the community grows. If your area isn't on the list, sign up and select Other or drop us a message at hello@twinfinsocial.com and we'll add it.

  • That’s what beta is for - we want to know.

    Not every match will click immediately, and that’s fine. Feedback helps us make better introductions over time. No pressure to keep surfing together if it’s not the right fit.

We’re a small project built between surf sessions with a lot of care. We’re currently in beta and still figuring things out as we go. Thanks for being here early.

Every signup, message and bit of feedback genuinely helps. Reach us at hello@twinfinsocial.com

Good surf sessions start here.
