Viana do Castelo Surf Forecast and Surf Report

Alright, this is Rusty, and I’m looking at what’s in store for us around Viana do Castelo.

The vibe here isn’t really firing at the start. We’re in a bit of a flat spell with only small, junk waves to look at. The first couple of days are just not worth paddling out for. The period from July 27th to July 31st is mostly weak, short-period swell, mixed with onshore or cross-shore winds. The water is sitting at 70° right now, which is 5° warmer than usual for this time of year – that’s a big deal, really warm for this spot.

The first recommendation that actually gets a bit of a nod is Wednesday morning, July 29th. The swell is tiny at 2ft from the WNW, period only 9 seconds, and the energy is weak (127). The wind is a light cross-off from the NW, so it’s clean enough for a longboard but nothing to wet your wetsuit for. The combined energy here is just a moderate 127.

Thursday morning, July 30th, is glassy. Swell is 2ft from the WNW, still a short 9-second period, energy is low (77). It’s surfable for a beginner, but the lack of power is obvious.

Friday morning, July 31st, shows a similar pattern: glassy conditions, 2ft from the NW, but with a very short period of 7 seconds. That’s weak, wonky surf.

Then we hit a real dry spell. From August 1st through to the morning of August 4th, the conditions are poor – mostly cross-shore or onshore breezes, weak swell, and the comment says “poor surf conditions” for most of those sessions. Not worth the drive.

The only real standout, the one that gets my heart pumping, is the morning of August 9th. That’s a Sunday, so it’s a great day to be out. Swell is 6ft from the NW, with a period of 10 seconds – that’s a proper groundswell. The energy is very strong at 784. The wind is a clean cross-off from the N. This is a proper push of swell, but listen: the period is over 9 seconds, and at a river break, that long-period energy can make it break a little too straight. Still, it’s the best on offer. The wind is clean, the power is there, and it’s not too big for the average surfer, though it’s getting close to the big end.

The morning of August 10th is also solid: 7ft from the NNW, period 10 seconds, energy is 735, and the wind is a clean cross-off from the N. That is a strong, powerful swell. Again, that long period at a river mouth can be a bit weird, but it’s a legit day.

The rest of the second week falls off. August 11th morning is 7ft from the NNW but the period drops to 8 seconds and the wind, while cross-off, is fresher. The afternoon is actually flagged as “too big for this break” – 8ft from the NNW with a 22 mph cross-off breeze. That’s expert territory, and even then, the river mouth is going to be a washing machine.

Overall, the best bet is the morning of August 9th. It’s the cleanest, most powerful day in the window. The morning of August 10th is a close second, but that 9th is the one to circle on your calendar. The rest of the time, you’re looking at weak, short-period junk or blown-out conditions.

Stay safe, keep your eyes on the horizon.
