Wetsuit recommendation
Shorty 2mm
At 21.9°C a 2mm shorty keeps surfers warm; lap swimmers can usually skip the neoprene.
Surf & watersports
Pleasant but not warm. A short-arm short-leg ("shorty") wetsuit traps body heat through the core while leaving arms and legs free. Open-water swimmers training for 30–60 minutes can usually go without; longer sessions benefit from a thin swim wetsuit.
Open-water swimming
Most swimmers fine to 60 minutes without; consider a 2mm swim suit beyond.
Recommendation tuned for Seixal Natural Pools's current water temperature. Individual tolerance, wind chill, and session length all matter — when in doubt, size up.
