The Lowdown
Alright mates, Rusty here again, this time in feet and miles for you.
Let’s break down the next couple of weeks at Arrifana. The early part is a bit of a struggle. Small, weak swell and bumpy onshore winds mean the first few days are pretty much a write-off. The water is sitting at 66°, which is about 5° colder than usual for this time of year – definitely a bit nippy, so grab a thicker wetsuit.
Friday the 28th morning is the first real bright spot. The wind swings to a cross-offshore from the NNW, and we get a solid pulse of groundswell – 8ft from the WNW with a 12-second period. The energy is strong at 1596, and it’ll be clean. That’s a big one though, for experts only. It doesn’t last long, and the afternoon gets choppy again.
After that, we go into a long stretch of clean but tiny surf. The wind is offshore nearly every day, but the swell is barely there. The weekend of the 30th and 31st, plus the start of September, is all cross-off breezes and waves mostly under 5ft. The energy numbers are low, mostly in the 200s and 300s. There’s a several-day gap where nothing really delivers.
Look ahead to Monday the 7th of September. The morning brings a 7ft WNW swell with a 13-second period, and the energy jumps to 1975. The wind is offshore from the N, so it’ll be clean. Again, that’s big power – for the experienced crew. The next morning, Tuesday the 8th, is still solid at 6ft with 11-second period and 1110 energy, with a gentle offshore breeze. Good, but not as punchy.
The real standout of the whole run, though, is Wednesday the 9th of September. The morning has a light ESE breeze – just about glassy – with a 5ft WNW swell. The energy is a solid 674, and the conditions are rated as very good. That’s the session to circle on the calendar. Clean, some power, and the wind is perfect.
Arrifana is a beach and reef setup, fairly exposed to the NW swell. It can get crowded sometimes, but on a Wednesday morning with that kind of glass, it’s worth the paddle.
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.
