Table - best surf conditions forecast for Viana do Castelo over the next 16 days.
Alright, folks, let's get into it. Rusty here, and I'm looking at the next couple of weeks for our local stretch. Gotta be straight with you – it's not going to be a classic run. We're staring down a long, quiet spell, with barely a ripple for days on end. The surf is going to be small and pretty average for the most part, so patience is the name of the game. There's a glimmer of something towards the very end, but it's a long wait.
The first proper surf I can get behind is a blink-and-you'll-miss-it window on the morning of Thursday, July 11th. We've got *Viana do Castelo* waking up to a glassy sea – wind is dead calm. Swell pushes in from the NW at a tiny 2ft, but the period stretches out to 11 seconds, which gives it some push for a river break. The combined energy is moderate (138). It's not a day for big waves, but it might be your only chance for a clean, easy paddle. Just remember, crowds are 'often' here on a good day, so it could get busy for what's on offer.
After that, it's back to a desert. The whole week from July 12th through to the 18th is a write-off. We get a bit of a bump on the morning of the 16th – a 3ft W swell with 6-second period – but the energy is weak (73) and the conditions are ordinary. The morning of the 17th sees a little more size, 4ft from the west, and clean conditions with a NNW cross-offshore breeze (119 combined energy). It's surfable, but it's very ordinary and not worth a special trip.
The wait finally pays off for those willing to look ahead. The real standout, and it's a distant one, arrives on Monday, July 21st and Wednesday, July 22nd. On the morning of the 21st, Viana do Castelo sees a 4ft NW swell with a 7-second period, but here's the kicker: the combined energy jumps to 227, which is a proper pulse of power. The wind is a clean, side-offshore N breeze at 15 mph. Then on the Wednesday morning (22nd) , we get a 5ft NW swell, also clean with a N wind, and even more energy at 225. The period is still short at 7-8 seconds, so it will be a bit raw and dumpy, but for a river break, the direction is good. These two mornings are the best on offer by a long shot. It's still a couple of weeks away, so keep an eye on the charts, but this is the one to circle.
Water temp at Viana do Castelo is sitting at 63°F, which is about 2°F cooler than normal for this time of year – nothing too crazy, just a touch on the fresh side.
Alright, that's the long and short of it. A whole lot of nothing, then a couple of promising mornings if you can wait it out.
Rusty.
