Viana do Castelo Surf Forecast and Surf Report

Alright, folks, let’s get into it. We’re looking at Viana do Castelo, a river mouth setup that’s exposed to the west. Water temps are feeling about average for the time of year, nothing wild there.

The next few days are a bit of a write-off, to be honest. Thursday the 27th is a complete no-go with heavy rain, cross-on wind, and poor surf, so don’t even bother. Friday the 28th actually has some serious swell rolling in – we’re talking 10ft from the WNW with a solid 11-second period, and the combined energy is pumping hard at 1785. But here’s the catch: that’s too big for this river break, so it’s really only for the experienced crew, and even then, it’s going to be a beast. The wind is light cross-onshore, so it’s not completely blown out, but expect a challenge. Saturday the 29th drops right back down to weak, marginal surf, and Sunday the 30th stays in that same mediocre zone with cross-shore winds.

Now, Monday the 31st morning is where things start to look interesting. The swell is a clean 5ft from the NW at 9 seconds, with a cross-offshore breeze from the north. That’s clean, workable surf with moderate energy (646), and the wave comment says “expect good surf conditions.” That’s your best bet early in the week. Tuesday the 1st of September stays clean but the swell is a little smaller, still surfable.

After that, we hit a bit of a lull from Wednesday the 2nd through Thursday the 3rd, with small, weak, ordinary waves. Friday the 4th afternoon has a small, clean 2ft swell from the NW with a longer 10-second period, giving you clean waves, but it’s small.

Here’s the real standout: Saturday the 5th of September. Morning and afternoon both look firing. Swell is 5ft from the NW with a long 12-second period, giving it real push and shape. The combined energy is solid at 668 and 534. And the wind? Glassy. Both sessions are glassy. That’s the pick of the entire forecast – clean, lined-up waves for everyone. The longer period means it’ll be a bit more powerful, but that’s a good thing. Keep an eye on it.

The following week offers a few more promising windows. Monday the 7th morning has glassy 4ft swell from the NW, and then Thursday the 10th morning looks very good: 5ft from the NW at 10 seconds, clean cross-offshore wind, and energy at 651. That’s another session to circle. The 11th of September Friday morning is also clean and surfable.

So, if you’re looking for the best of the bunch, lock in Saturday the 5th of September. That’s the one. Viana do Castelo will be clean, with a solid, long-period NW swell. Get on it.
