The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the menu for Afife. We’ve got a bit of a dry spell to kick things off, so don’t be in a rush to grab your board.
The first week is a write-off, I’m sorry to say. From Monday the 17th right through to the end of August, we’re looking at poor surf. The wind is almost always cross or cross-onshore, and the swell is either too small or too messy. There’s a glimmer on Tuesday the 18th morning with waist-high 3ft swell from the NNW and glassy conditions, but the wave energy is low at 114 and the score isn’t there. It’s surfable, but barely worth the paddle. After that, the wind just keeps howling from the north, with gusts up to 18-25 mph on the 22nd, 23rd, 24th, 26th, and 29th, making it lumpy or choppy. The swell does build over the 21st and 22nd, with combined energy hitting 567 and 636, but with fresh cross-onshore winds, it’s just a mess. By the 25th, we’re down to 1ft and flat. Honestly, there’s a big gap of about 10 days here with no real recommendations.
Now, hold onto your leash, because the real standout is waiting for us on Tuesday the 1st of September. This is the one to circle on your calendar. Tuesday morning at Afife is looking like the peak of the entire outlook. We’ve got a 7ft swell from the NW, with a period of 8 seconds, and the combined swell energy is a solid 584. That’s moderate to strong energy, and it’s going to give the waves some punch. But the real magic is the wind – it’s glassy, with a light 3 mph breeze from the WSW. That’s offshore for this spot. The water temp is about 66°F, which is pretty normal for this time of year, nothing to worry about.
This is a beginner-friendly break, and while 7ft is getting up there, it’s still manageable for a confident beginner or a keen intermediate. Just keep in mind that the period is on the shorter side at 8 seconds, so the waves will be a bit more frequent and less of a groundswell. The direction is NW, which is nearly right for the optimum W direction, so it’s lining up well. No crowds mentioned, so you might have it to yourself.
Later on Tuesday afternoon, the swell jumps to 8ft, but the wind goes cross-on and the score drops. So the highlight is definitely the morning session. If you can only go once, make it dawn on the 1st of September.
For the rest of the outlook, things stay poor. The 30th of August has a 6ft NW swell but with a fresh 19 mph cross-onshore wind, it’s lumpy. The 31st is small and choppy. Nothing else compares to that Tuesday morning.
So, to sum it up: wait out the first week, it’s going to be a frustrating stretch with no real surf. The best bet, and it’s a good one, is the glassy 7ft NW swell on the morning of the 1st of September. That’s your winner.
Rusty.

Information about the Afife Surf forecast
The above surf forecast table for Afife provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Afife can be found by selecting the local surf guide option on the grey menu. Our Afife surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Afife) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Afife may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Afife is 10 km (6 miles) from Viana do Castelo. If you plan a holiday in Douro and Minho, look for hotels and other accommodation in Viana do Castelo. Viana do Castelo has rooms for a wide range of budgets as well as car hire and transport links.
