The Lowdown

Alright, mates, let me walk you through what’s cooking in the lineup over the next couple of weeks. You can stash your boards for a while because, honestly, it’s a long, dry spell. The only spot we’re looking at is Coxos, a solid reef break that’s fairly consistent. Right now, the water temp is 69°F, which is about 0.5°F warmer than normal for this time of year – so, pretty average.

We kick off Friday the 14th with a bit of a dud – a small 3ft WNW swell, but a 30 km/h cross-on wind from the NNW is chopping it up. No good. Saturday the 15th is a bit bigger, around 8ft from the NNW, but that same cross-on wind is just ruining it. Sunday the 16th morning has a 7ft NNW swell with a light cross-on, but it’s still only marginal. The afternoon drops to 6ft with onshore wind – forget it.

Now, Monday the 17th morning is where things get interesting. We’ve got a 6ft NNW swell, a glassy offshore wind from the SSW, and the guidance says the swell direction is right on the money. The combined energy sits at 394 (moderate), and the winds are light enough for clean, glassy conditions. This is the one standout in the whole window. It’s a solid size for intermediates, but with that offshore breeze, the reef at Coxos (Ericeira) will be pretty clean. Monday afternoon, though, the wind swings back onshore, so don’t sleep in.

After that, it’s a long, grim stretch. Tuesday 18th morning has a 5ft cross-off wind, but it’s clean – still only marginal. The rest of the week from Wednesday 19th through to the weekend is just small, weak, and blown out. Combined energy drops to as low as 43 (weak) on Wednesday afternoon. Sunday the 23rd and Monday the 24th see some bigger swell – 8ft and 5ft – but with cross-on winds up to 40 km/h, it’s a full-on mess. This is a beach-and-reef setup, so with that much wind and chop, it’s looking more interesting for kite surfers than paddle surfers.

We get a bit of a tease on Thursday the 27th morning: a 4ft NW swell, glassy conditions from the NNW, and a moderate combined energy of 341. The period is 10 seconds, so there’s some shape to it. It’s only rated as “expect good surf conditions,” but after all that nothing, it’s a chance to get wet. The wind is totally off, so Coxos will be clean.

Finally, looking way out to Saturday the 29th, we’ve got a promising-looking 8ft WNW swell with a 12-second period and a huge combined energy of 1425 (very strong). The wind is light from the NNW, so it’s onshore, but it’s only a gentle breeze. The guidance says optimum swell is from the NNW, and this is WNW, so it’s a bit off. It’s a strong, long-period groundswell, which is more suited to point breaks and reefs, so Coxos might handle it, but it’ll be a big, powerful wave – only for experts. That’s well into the second week, so take it as a promising but uncertain prospect.

Bottom line: if you can get out Monday morning the 17th, that’s your best bet. After that, it’s a lot of waiting for the 27th or the 29th. Hang tight.

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.
