The Lowdown
Alright team, Rusty here. Let’s talk about this stretch of coast.
We’re looking at Coxos (Portugal), a reef that loves a good NNW swell. The water is about 69°F, which is pretty standard for the time of year.
The first few days are a write-off. From Tuesday the 21st right through the rest of the week, it’s small and weak. Wave heights are 2ft to 3ft, with short periods under 8 seconds, and the wind is messing everything up with cross-onshore and onshore breezes. The combined energy is low, well under 100. You’re looking at a gap of several days with nothing worth paddling for.
The weekend of the 25th and 26th sees a pulse of swell, hitting 5ft to 7ft, but it’s a total mess. Fresh onshore winds up to 20-22 mph are blowing the tops off. The energy is there, in the 300s to 600s, but it’s all wind-chopped. Honestly, this is more of a kite session than a surf session.
It stays poor through the 27th, with lumpy, choppy conditions.
The one to circle is Tuesday morning, the 28th of July. That’s your window. We’ve got a clean 4-5ft swell from the NNW, with an 8-second period, and the wind is glassy. Dead calm. Combined energy is a solid 304, so there’s proper push. That’s your standout. Get in the water early because the wind shifts cross-onshore by the afternoon.
After that, it’s mostly grim. The 29th has tiny surf, and the 30th is flat with a pathetic 1ft. The 31st brings a 4ft swell, but the period is a weak 5 seconds and the wind is onshore. Into August, it’s more of the same: strong winds and small, chopped-up waves. There’s a faint hope on the 5th of August with a glassy morning and a 4ft swell, but it looks ordinary.
Bottom line: a long dry spell, one killer dawn patrol on the 28th, and then a lot of waiting. That Tuesday glass-off is the real deal.
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.
