Viana do Castelo Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into the next 16 days for our local stretch.

The forecast is a bit of a slow burn, but it builds to some proper moments. There’s a gap right at the start: Saturday the 29th is a write-off with weak, messy cross-shore wind and only marginal 5ft swell. Not worth paddling out for.

Sunday the 30th morning sees a glimmer of hope. The swell picks up to 5ft from the NW with a 9-second period, and we get a clean cross-offshore breeze from the NNW. The energy is moderate (388), and it’s the first decent chance to get wet, though it’s still just breaking in. Sunday afternoon turns to junk, so hit it early.

Monday the 31st morning is the first real standout. Clean, clear skies, a 5ft NW swell at 10 seconds, and a gentle cross-offshore breeze. The energy jumps to strong (517), and the conditions are clean. This is the best of the first week. Monday afternoon gets windier and drops off.

The week stays rideable but unremarkable through to Thursday the 3rd, with small 4ft to 3ft NW swells and light winds. Nothing to get excited about.

Then Friday the 4th morning delivers the absolute highlight of the whole outlook. We’ve got a 5ft NW swell, but the period stretches to 12 seconds – that’s proper groundswell energy. The combined energy is a solid 733, the wind is light and cross-offshore, and it’s clean. This is a long-period swell, so it’ll wrap in nicely at the river mouth, with longer gaps between sets making the paddle out easier. This is the one to circle on the calendar. Friday afternoon holds up at 6ft but with a moderate breeze, so it’s not as clean.

The second week is more of a mixed bag. Saturday the 5th and Sunday the 6th are average with onshore winds and smaller swell. Monday the 7th morning shows another pulse of long-period WNW groundswell at 5ft, 11 seconds, with light winds and clean conditions – energy is strong (676). That’s a solid session. After that, the surf fades into smaller, wind-affected 3ft to 3ft days through Wednesday the 10th.

Thursday the 11th sees a very long-period swell (14 seconds) from the WNW, 5ft, but the wind is light cross-shore, not ideal. The energy is huge (809), but it’s a touch messy. Friday the 12th morning cleans up nicely with a 5ft WNW swell, 11 seconds, light cross-offshore breeze, and moderate energy (488). That’s a good option. The final days (13th September) are onshore and less appealing.

For the best on offer, I’d say Friday the 4th morning is the standout – that long-period NW groundswell with light offshore wind is the cleanest, most powerful session of the window. Monday the 7th morning is a close second for the same reasons.

The water temp is sitting at 64°F, which is a bit colder than usual for this time of year – about a degree and a half off. You’ll want a decent spring suit, maybe boots if you’re out early.

At Viana do Castelo, the crowd can be a factor, especially on the better days – get there early for the best of it.

Stay stoked,
Rusty
