Table - best surf conditions forecast for Praia do Porto over the next 16 days.
Right then, let's have a look at what's on offer for Praia do Porto over the next couple of weeks.
First things first – the water's sitting at 59°, which is a whopping 7° colder than normal for this time of year. That's very unusual, so you'll want a thick steamer and maybe some boots if you're heading out.
Things kick off this Sunday morning, July 12th, with a clean, 5ft southerly swell. The period is a solid 11 seconds, giving the waves some proper push, and with a light offshore breeze, it'll be glassy. The combined energy is moderate (870). It's a decent, fun-sized wave for the beginner-plus crew. Sunday afternoon the wind holds offshore, but the swell jumps to 7ft and the period drops to 7 seconds – that's a shorter, less organised wave, but still ridable.
Monday the 13th is another good shout. The morning brings a clean 7ft swell from the south with moderate wave energy (1033) and a gentle offshore. Keep an eye on it, because at 7ft it's starting to push the limits for beginners. The afternoon drops back to 4ft but the wind stays gentle and offshore.
Now, here's the standout of the whole forecast. Tuesday morning, July 14th, is the pick of the entire run. The wind goes absolutely glassy – dead calm – and you've got a 6ft swell rolling in from the southeast with a 10-second period. The combined energy is solidly moderate (714). It's going to be clean, lined up, and just a joy. That morning session is the one to aim for. The afternoon turns ugly with onshore wind, so get it while it's good.
Unfortunately, that's where the fun stops for a while. From Tuesday afternoon (July 14th) all the way through to the morning of Wednesday, July 22nd, it's a write-off. That's over a week of onshore winds, cross-on choppiness, and generally poor conditions. There are a couple of marginal mornings in there, but honestly, not worth paddling out for.
The surf finally starts to clean up again on the afternoon of Wednesday, July 22nd, with a clean 4ft swell and offshore winds. It's small but at least it's surfable. Thursday the 23rd stays small and clean in the afternoons.
The next real highlight comes on Friday the 24th. The morning serves up a clean 3ft southerly swell with a long 11-second period and an offshore breeze. The afternoon, though, is even better – glassy conditions again with a 3ft southerly swell and a 12-second period, giving it plenty of energy (531). That's a beautiful little clean wave for a longboard or a funboard.
Saturday the 25th keeps the trend going with a clean 4ft southerly swell and gentle offshore winds in the morning. The weekend looks fun, if not huge.
Then we get to the very end of the forecast, Monday morning, July 27th. The swell jumps right up to 8ft from the SSE. That's big, expert-only territory, and with a cross-on breeze and short 9-second period, it's going to be a messy, powerful beast. Leave that one to the heroes.
So to sum it up: the absolute best sessions are Tuesday morning, July 14th (glassy, 6ft SE), and Friday afternoon, July 24th (glassy, 3ft S). Get on them.
