The Lowdown
Alright, Rusty here. Let's talk about what's on the table for the Arrifana zone over the next couple of weeks.
Look, I'm gonna be straight with you – this is a tough stretch. For the first week, from Friday the 7th all the way through to Thursday the 14th, it's a real struggle. The swell is tiny, mostly under 3 ft, with a weak energy reading (50-238). The wind is a constant cross-off from the north, which is okay for surface texture, but there's just no grunt in the ocean. The water is sitting at 68°F, which is about 3° cooler than usual for this time of year, so you'll feel that little nip in the air. Honestly, it's a write-off for the first seven days.
Now, we do get a small pulse on Friday the 14th morning. The swell bumps up to 3 ft from the WNW with a longer period of 11 seconds, and the energy jumps to 238. The wind is light and cross-off. It's still not great, but it's the first sign of life. Things get a little more interesting early on Saturday the 15th. The morning has 5 ft of NW swell, with moderate energy (334) and light cross-off winds. The wave comment says "expect good surf conditions," but don't get too excited – it's still only a 2 out of 10. The size is getting there, but the quality is just average.
The real standout is Friday the 21st of August. The morning brings a solid 8 ft of NW swell, with a strong energy reading of 843. The wind is a clean cross-off from the north at 12 mph. That's a proper sized swell and it will be clean. This is a big one, so it's for experienced surfers only – it's too much for a beginner. The direction is a bit north of the optimum NW, but with that size and clean wind, Arrifana will have some proper lines. The Saturday morning after that also has 6 ft of NW swell with clean winds, but it's a step down in energy and quality.
To sum it up: the first week is a total bust. The second week offers a glimmer, but the only real standout where you should seriously consider making the trip is Friday the 21st of August. Get your big-wave board ready.
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.
