The Lowdown
Alright folks, Rusty here. Let's talk about Arrifana. This spot's usually a consistent performer with that NW swell and a clean NE offshore, but right now we're looking at a long, quiet stretch.
The water's sitting at a typical 69°, nothing out of the ordinary for mid-July. For the next two weeks, it's pretty much a bust. From July 14 right through to July 28, every session is a write-off – tiny, weak, messy slop. Wind's mostly cross-off but the swell's barely a ripple, with combined energy numbers in the double digits or low triple digits, and often under 100. There's no push, no shape. You'd be staring at flat lines.
Then, right at the tail end of the forecast, things finally wake up. On the morning of July 29, we get a proper pulse – 5ft of clean NW groundswell rolling in with a 10-second period. The wind is light out of the north, cross-off and clean, leaving the surface glassy. Combined energy jumps to 491 – that's proper juice. It's not a beginner wave at that size, but for the advanced crew who know Arrifana's reef and beach setup, that's the morning to circle. The afternoon looks a bit more marginal with a bump in wind, so hit it early.
That's it – one true standout after a long dry spell. Keep an eye on the forecasts; a blank run like this tends not to last, and when it turns, Arrifana can fire.
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.
