The Lowdown
Alright, let's be real. The next 16 days at Arrifana are looking like a total bust. The water is 68°F at the start, which is a bit colder than normal for this time of year, so layer up.
The first week is a grind. From Monday, August 31st through Sunday, September 6th, it's all poor surf conditions. We've got cross-offshore winds, but the swell is tiny and weak. The combined wave energy maxes out at 470 on Monday afternoon, which is weak to moderate, but the swell is only 5ft from the NW with a 9-second period—a messy windswell. The waves are clean, but there's no power. A bump on the 3rd afternoon is cross-shore and choppy, not worth it. The 4th and 5th are tiny with onshore winds.
The second week is no better. Monday, September 7th morning is the only "marginal" call, with a 4ft NW swell and a cross-off breeze, but the period is a short 7 seconds. The energy is 267, still moderate. After that, it's back to poor surf. The one glimmer is Sunday, September 13th morning, with a "surfable" but "very ordinary" rating. We'll get 3ft from the WNW with a light 10 km/h cross-offshore breeze from the north. The combined energy is a weak 146, and the period is just 7 seconds, so it'll be weak and a bit choppy.
That's your only shot. The rest is flat and windy. For an advanced break like Arrifana, a beach and reef setup, you need power, and it's just not here. If the wind really blows, this might be more of a kite session than a paddle one.

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.
