Viana do Castelo Surf Forecast and Surf Report

Alright, Rusty here. Let’s take a look at what’s cooking for our local stretch over the next couple of weeks. Honestly, it’s a pretty flat and frustrating run for the most part. The good news is, there’s a bit of a pulse early on, but after that, things drop right off. For those of you with a shortboard and a long memory, we do have one session that stands out above the rest.

The first real chance to get wet kicks off on Monday afternoon, 31 August. Viana do Castelo (river) will be seeing a solid 6ft swell from the NW. That combined energy is sitting at a moderate 665, so there’s some push behind it, but it’s a bit of a mixed bag. The wind is a cross-off from the NNW at 16 mph, which will keep the surface reasonably clean. The water temp is 65°, which is about average for the time of year, so nothing unusual there. This is the best on offer for the whole outlook, but it’s only for the more experienced crew—that 6ft is a bit much for beginners, especially on a river mouth that can get shifty.

Now, for the standout moment. That’s Tuesday morning, 1 September. The swell drops to a more manageable 5ft from the NW, but the wind is the real story here. A light N breeze at 6 mph, cross-off, making for clean, lined-up waves. The combined energy is still moderate at 369, and the period of 9 seconds means decent shape. This is the cleanest, most user-friendly window of the entire forecast. If you can only paddle out once, this is it. The crowd situation at Viana do Castelo can be an issue at times, so get in early.

After Tuesday afternoon, the whole thing goes flat. Wednesday the 2nd of September drops to a tiny 2ft, and by Wednesday afternoon we’re looking at a pathetic 0.7ft with a period of 16 seconds—that’s a ghost swell. The energy is a weak 48. Forget it.

The rest of the first week and into the second is a long, drawn-out gap of mostly poor or very ordinary conditions. There’s a glassy window on Thursday morning, 3 September, with a light SSE breeze at 3 mph and a tiny 2ft swell, but it’s not going to get the heart racing. Saturday afternoon the 5th sees a clean 3ft from the WNW with an offshore NE breeze at 9 mph, but it’s still small.

From the 6th of September onwards, it’s a bleak picture. Swell stays small to medium, but the wind is either onshore, cross-onshore, or howling cross-off at 19 to 25 mph. The wave energy drops into the weak range (80-150) for most of it. There’s a moment on Wednesday afternoon, 9 September, with a glassy surface and 4ft from the NW, but the period is a short 7 seconds and the energy is only 154. It’s surfable, but ordinary. By the second week, the wind is just too strong to make anything worthwhile, especially on the 10th and 11th with fresh to strong breezes.

In short: grab that Tuesday morning, 1 September, because after that, you’re looking at a lot of days where you’re better off cleaning the wax off your board and waiting for the next system. The setup here is a river mouth, so when the swell is small and the wind is light, it can work, but the long-range stuff is too unreliable to get excited about. If the wind keeps up like this, some of those bigger, choppier days might be more interesting for the kite crew than for us paddle surfers.

Stay stoked, but keep your expectations in check for the next fortnight.
