The Lowdown
Alright, folks. Rusty here. Let’s take a hard look at Arrifana. This is a prime exposed beach and reef setup that needs a solid NW swell to do its thing. The optimum direction is NW, and we’re getting that, but the timing and the wind are going to test your patience.
We’re looking at a pretty quiet start. For the first week, from Monday the 20th through Saturday the 26th, the surf is tiny and mostly messy. The wind is a persistent cross-offshore from the north, which is clean, but the swell is weak. On Monday the 20th, we’ve got a tiny 2 ft NW swell with a short period, so the wave energy is barely a whisper. That’s a full 7 days of "poor surf conditions" on the cards. No point in paddling out for that.
The first real sign of life doesn’t arrive until Sunday the 26th. The swell bumps up to 6 ft from the NW, but the period is still short at 8 seconds, and the wind is a stiff 19 mph cross-off. The wave energy is moderate (378), but it’s going to be a bumpy, blown-out mess. That’s a kite-surfing day, not a surfing day, especially for a beach and reef break.
The standout window, and the only real hope in this 16-day run, is a small window around Tuesday morning, July 28th. The swell is 5 ft from the NW with a period of 9 seconds, which is a nice, solid, long-period groundswell. The water temperature is 69°, which is about average for the time of year. But the real magic is the wind: glassy, dead calm, from the SSE. That’s as good as it gets for clean conditions. The wave energy is moderate (281) and the forecast is calling for "good surf conditions." This is your best shot. It’s not huge, but it will be clean, lined-up, and fun for the advanced crew. Crowds are possible at Arrifana, so get there early.
After that, the surf drops off again. Wednesday the 29th has glassy conditions but puny 3 ft surf. The rest of the week into early August is a procession of small, weak swells in the 1.0 ft to 2 ft range, with the wind turning onshore, ruining any chance of a clean wave. There’s another pulse on Monday the 3rd of August with 5 ft from the NNW, but that’s over a week away and the wind is back to a strong cross-off, so it’s a long shot. The energy is moderate (243-273) but the quality isn’t there.
Honestly, if you’re chasing clean waves, circle Tuesday the 28th on your calendar. The rest of the month is a write-off unless the forecasts change. It’s a dry spell, but it happens here.
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.
