The Lowdown
Hey, I’m Rusty. Let’s talk about Praia do Porto for the next couple of weeks. The beach/jetty setup is fairly exposed to the swell, and the best direction is from the southeast. Water temp is about 19°—dead average for this time of year, no worries.
The real window starts Sunday the 9th and runs through Tuesday the 11th. That’s your best bet. Sunday morning you’ve got a clean 6ft swell from the south with a short 8-second period, but offshore wind from the SSW makes it smooth. The combined energy is moderate (891). By Sunday afternoon, the swell jumps to 8ft from the south, period 11 seconds, with cross-off wind at 15 km/h—clean and meaty. The energy is strong (2216). That’s getting into the size range for experienced surfers.
Monday the 10th morning is a beauty: 8ft from the south-southwest, period 13 seconds, light offshore wind from the WSW. That’s a groundswell, long period, so you’ll get nice shaped waves but longer waits between sets. Energy is very strong (2870). Monday afternoon drops to 6ft but stays clean. Tuesday the 11th is the real gem—completely glassy both sessions, with 6ft and 6ft south swell, period 12 seconds. Energy is moderate (1049 and 919). No wind, just clean lines. That’s the standout.
After that, it gets messy. Wednesday the 12th and Thursday the 13th are mostly cross-onshore and choppy. The swell holds around 5ft to 7ft but the wind ruins it. Friday the 14th and Saturday the 15th offer a brief cleanup. Friday morning has 6ft from the south-southeast, period 14 seconds, with offshore wind from the SW—clean, moderate energy (1340). Saturday the 15th morning is glassy again with 5ft south swell, period 12 seconds (837 energy). Nice, but smaller.
From Sunday the 16th through the 23rd, it’s mostly poor. Swell shifts to east and east-northeast, short periods, and onshore wind. A few bright spots: Tuesday the 18th afternoon has 8ft east-northeast swell, period 9 seconds, with light cross-off wind from the SSW—clean and powerful (1702 energy), but only for experts. Wednesday the 19th morning is glassy with 7ft, period 9 seconds, but short period.
The tail end of the forecast, around Saturday the 22nd, drops to 4ft from the southeast, period 13 seconds, with offshore wind—gentle and clean. Low energy (546), but good for a longboard.
The best is Tuesday the 11th—glassy, clean, 6-6ft south swell, 12-second period. That’s the one to mark on your calendar. The Monday the 10th morning is also a cracker, but the Tuesday is the standout for pure, wind-free conditions. Crowds are sometimes an issue here, so get in early.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Praia do Porto may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
