Viana do Castelo Surf Forecast and Surf Report

Alright, Rusty here, checking in from the break.

Right now, we’re in a bit of a flat spell. This river mouth isn’t doing much for a few days, with choppy, cross-shore winds messing up anything that tries to form. The wait will be worth it though, because things finally start to clean up later in the week.

Our first real chance to paddle out comes on Thursday the 27th in the morning. Viana do Castelo will see a clean 6 ft swell from the WNW with an 8-second period. The wind is a light, cross-offshore breeze from the NNW, so the face will be pretty clean with only a slight air moving. Wave energy is moderate (386). It’s not the biggest swell, but it’s the first day we get proper conditions after a few days of slop.

The standout of this whole outlook is Friday the 28th. That morning, it goes glassy. Absolutely flat calm, zero wind, with a solid 8 ft groundswell rolling in from the WNW. That’s a big number and the combined energy jumps to strong (1324). The period is 10 seconds, so there’s decent power behind it. That said, this is a river break, and 8 ft is getting sizeable; I’d say this one is for experienced heads only. The crowds here can be an issue, and on a morning this good, expect the lineup to be busy. I would not recommend this for beginners.

Saturday the 29th morning pulls back a touch to a more manageable 5 ft from the WNW with that same 10-second period. The wind is back to a light cross-offshore from the NNW, keeping it clean. Wave energy is still solid (788). This is probably the best bet for a strong session that isn’t as intimidating as Friday.

After that, the swell hangs around but drops in size through the end of August and into the start of September. Clean mornings with cross-offshore winds pop up on the 30th (4 ft) and the 31st (4 ft), but the wind picks up stronger, especially on the 31st afternoon when a fresh 19 mph breeze hits.

Heading into September, we get another spike. The morning of Wednesday the 2nd of September shows a clean 7 ft swell from the WNW, period of 10 seconds, with a very light cross-offshore breeze. Wave energy is up there again (844). Like the 28th, this is big for the spot and considered too large for most, so we’re looking at an expert-only window.

The biggest pulse of the whole run hits on Thursday the 3rd of September. That morning is dead flat calm, glassy, with 8 ft from the NW and a long 11-second period. The energy number blows up to 1346. That is a serious groundswell with serious power. It'll be a sight to see, but this river mouth will be absolutely thumping and likely unruly for anyone without deep experience. The direction is a good match for the spot's ideal W-NW window, but the size is the limiting factor.

To wrap it up, we’ve got a slow start, a few good clean days from the 27th through the 31st, and then a run of oversized, high-energy days for the experts starting on the 2nd of September. If you’re intermediate, aim for the 29th. If you’re seasoned and want a challenge, the 28th of August or the morning of the 3rd of September is your ticket. If you're learning, give this whole period a miss, especially when it's pushing 6 ft or more.

Stay safe out there.
