Table - best surf conditions forecast for Coxos over the next 16 days.
Alright, grab a seat. It's me, Rusty, and I’ve got to be straight with you – this stretch of the calendar is looking pretty grim. We’re looking at Coxos (Portugal), and for the heart of the forecast period, there’s hardly a whisper of decent surf. The first glimmer of anything rideable doesn't pop up until the morning of Sunday the 12th, and even that’s a sorry excuse.
Through Tuesday the 7th and all the way to Saturday the 11th, it’s a total write-off. The swell is tiny, the winds are messy, and you’d be fighting for scraps. The water temp is sitting at 67°, which is about average for this time of year, so nothin' special there.
Sunday, July 12th – Monday, July 13th: The Only Real Window
After a long, flat wait, we get a tiny sniff of life. Sunday morning shows a weak 0.7m (2ft) NW swell, with a combined energy of just 134 – that’s weak, folks. But the wind goes *on* from the NW, and the conditions are labeled as "marginal". You might get one or two, but don’t expect much.
The real standout, and I mean the *only* standout in this whole outlook, is Monday morning, July 13th. We’ve got a very small 0.9m (3ft) swell coming from the NNW with a short, weak 8-second period. The combined energy is a weak 110. But here’s the kicker: it’s glassy. The wind is a whisper from the WNW, and that glassy water will make Coxos look as clean as it can on a tiny day. It’s not gonna be powerful, but for a paddle and a few slow lines, this is your best bet. The break is fairly consistent and exposed, and the optimum direction matches the swell from the NNW. Crowds are "often" here, so expect company even on a small day.
After Monday afternoon, it’s back to the choppy, messy junk. Tuesday the 14th and Wednesday the 15th see the swell drop back to 0.4m (1ft) with short periods. Late Thursday the 16th shows a bit more size – 1.1m (4ft) from the W – but it’s all on-shore slop with a 7-second period. That’s the kind of weak, bumpy stuff that makes a reef break like Coxos look like a washing machine.
The second week, from the 20th onward, is worse. Tiny 0.3m to 0.8m (1-3ft) swells with periods as low as 5 seconds and relentless cross-onshore wind. There’s no light at the end of that tunnel. If you're itching for a paddle, set your alarm for Monday the 13th. Otherwise, the board stays in the bag.
Rusty.

Information about the Coxos Surf forecast
The above surf forecast table for Coxos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Coxos can be found by selecting the local surf guide option on the grey menu. Our Coxos 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 (Coxos) 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 Coxos 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.
