Table - best surf conditions forecast for Arrifana over the next 16 days.
Alright, Rusty here. Let's break down what's going on in the water.
It's a slow start for the first few days. Arrifana is mostly flat and choppy, so keep the board in the car.
Things start to stir on Saturday, July 18th. A new swell fills in, with Saturday morning seeing 5 ft of NW windswell, a short 7-second period, and moderate wave energy around 220. It's clean, but a bit raw. By Saturday afternoon, it's bumped up to 6 ft from the NNW, still at 7 seconds, with energy climbing to 323. Still clean, but this is for the experienced crew.
Sunday, July 19th, is a serious step up. The morning brings 6 ft from the NNW, and the energy is a strong 397. The period is still short, so expect lumpy, powerful surf. This is experts-only territory. Sunday afternoon pushes it to 8 ft from the same direction, with an energy reading of 645. That's a lot of power, but with that short period, it'll be a thumping, closeout-heavy day. It's a marginal forecast due to the conditions, but the size is no joke.
The real standout window looks to be Monday, July 20th. Monday morning is the one to circle on the calendar. We've got a solid 6 ft of NNW swell, the period ticks up to 8 seconds, and the energy is a healthy 466. The wind is a light cross-offshore, keeping the surface glassy. The water temperature is about 69°, right around the average for this time of year. For anyone who knows Arrifana, this is a proper session. The swell direction lines up well with the optimum, and the moderate energy suggests solid, rideable waves.
The swell sticks around for the next few days, but slowly fades. The wind stays primarily cross-offshore, keeping conditions clean, but the size drops off. There's another spike in energy around July 23rd and 24th, with waves hitting 8 ft and energy soaring over 1000, but again, short period and stronger winds make it a game for the experts only. It's powerful, but not a classic.
In short: the first week is quiet. Your best bet for a clean, fun session is Monday, July 20th. The bigger stuff later on is for the brave and the bold.
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.
