The Lowdown
Alright, Rusty here again, same story, different numbers.
We’re looking at a quiet start, but there are a few windows where it’ll be worth paddling out. The first real action kicks off this Sunday morning at Foz do Lizandro. It’s a river mouth setup, beginner-friendly, and fairly consistent. The water is sitting at 65°, which is much colder than normal for this time of year, so you’ll want a good wetsuit. Sunday morning we’ve got clean 3ft of NW swell, period a solid 13 seconds, with a light cross-off breeze from the SSE. The combined energy is moderate (330). It’s not huge, but it’ll be clean and lined up. Crowds are possible here.
Monday morning is the real standout of this first week. The 14th, early session, looks glassy with a 3ft NW swell, 11-second period, and that glassy wind from the SSW. Energy is moderate (306). If you can get out there, that’s the one to aim for. The river mouth setup will handle that longer-period groundswell well.
Then it goes quiet. From Tuesday morning the 15th right through until the morning of Saturday the 21st, it’s pretty much a write-off – small, messy, cross-shore winds, and barely any energy to speak of. That’s a full six-day gap with nothing worth chasing.
Things start looking interesting again on Monday the 21st. Morning brings a 6ft NW swell, 13-second period, and strong combined energy of 1010. The wind is a gentle cross-shore from the south, so there’s a bit of chop, but there’s power in the water. This is more of a solid, chunky day – might be too much for beginners, but for the more experienced, it’s got potential.
The true highlight of this whole forecast lands on Tuesday the 22nd. Morning session, clean as a whistle, with a cross-off breeze from the NNE. Swell holds at 5ft from the NW, 12-second period, and energy is pumping at 811. That’s the day to circle on the calendar. The river mouth will be handling that long-period groundswell nicely, and the wind will keep it glassy. This is your best bet.
After that, it drops off again. Wednesday the 23rd through to the end of the period is mostly flat or tiny, with only a few very small clean moments on Thursday the 24th morning and Monday the 28th morning. That Monday the 28th has a 3ft NW swell, 14-second period, glassy conditions, and energy of 241 – worth a dawn session if you’re keen.
So, to sum it up: Sunday morning the 13th for a gentle intro, Monday morning the 14th for a glassy gem, and Tuesday the 22nd morning is the big one. Get on it.
Rusty.
