The Lowdown
Right, gather 'round, me hearty. Rusty here, with the long-range look for Arrifana. A bit of a mixed bag this one, so let's get into it.
The first real chance for a surf comes in on Saturday morning, the 22nd. We're looking at a clean 4-foot swell from the NW, with a period of 10 seconds, and a light cross-offshore breeze. The combined energy is moderate at 316, and it's a bit colder than usual for this time of year, with the water at 68°. This is a solid, clean start to the weekend, but it's not the big one.
Things go a bit pear-shaped after that, I'm afraid. From Saturday afternoon right through the rest of the week and into the next, the conditions are pretty rough. We've got onshore winds, choppy water, and a lot of swell that's just not clean. It's a real blank run, with no good surf on offer for days. The wind is just not playing ball.
Keep your eye on Friday, the 28th. That's the standout. The morning brings a clean 7-foot swell from the NW, with a 11-second period, and a solid cross-offshore wind from the north. The energy jumps right up to 1236. This is powerful, clean, and for the advanced crew only. The afternoon, with an 8-foot swell and 1535 energy, is even more serious but still clean. This is a big, powerful NW groundswell hitting a fairly exposed spot. The period is long, so expect some lulls between sets, but the waves will be well-shaped and have plenty of punch. This is not for beginners.
The following Saturday morning, the 29th, still has some clean, solid 6-foot swell hanging around, but the energy drops a bit, and it's a marginal call. Then we're back to smaller, choppier, or onshore conditions for much of the following week. There's a flicker of life on Saturday, the 5th of September, with a very long-period 13-second swell from the NW, but a cross-shore wind will chop it up a bit.
So, the verdict: The first Saturday morning is a nice, clean warm-up. The real gold is Friday, the 28th. That's the one for the big-wave hunters. It will be powerful, clean, and likely to have some crowd. The rest of the period is largely a write-off for good, clean, paddle-friendly surf.
Rusty.

Information about the Arrifana Surf forecast
The above surf forecast table for Arrifana provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Arrifana can be found by selecting the local surf guide option on the grey menu. Our Arrifana 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 (Arrifana) 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 Arrifana 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.
Arrifana is 27 km (17 miles) from Lagos. If you plan a holiday in The Algarve, look for hotels and other accommodation in Lagos. Lagos has rooms for a wide range of budgets as well as car hire and transport links.
