The Lowdown
Alright folks, Rusty here. Let’s get into it for Santa Maria de Oia. This is a reef break for the advanced crew only, and it’s fairly consistent, but it’s exposed to the swell. The water is sitting about average for this time of year, nothing unusual there.
Right now, the first half of the outlook is pretty grim. We’ve got a long stretch of poor surf conditions from the 4th right through to the morning of the 7th. Winds are mostly cross or onshore, with swell energy bouncing between 128 and 161 (moderate wave energy), but it’s all messy. The swell is tiny – around 2ft to 3ft – and the period is short, under 10 seconds, so it’s weak and jumbled. Not worth paddling out.
Then, on the morning of Friday the 7th, we get a tiny window of hope. The wind goes glassy with a light breeze from the WNW, only 3 mph. Swell is a pathetic 2ft from the NNW, with a period of 8 seconds, and the energy drops to 73 (weak). The conditions are described as “surfable waves but very ordinary conditions.” It’s clean, but there’s just not enough swell to get excited about. Still, if you’re desperate for a slide, that’s your best bet early on. Crowds are possible here, so keep an eye out.
After that, it’s back to the doldrums. Saturday the 8th and Sunday the 9th are poor, with onshore wind and tiny swell. The morning of Sunday the 9th does have another glassy moment with 2ft from the NW, but it’s still weak (76 energy). Just a tease.
We then hit another flat spell from Monday the 10th through to the morning of Friday the 14th. The swell is basically non-existent, and the wind is mostly onshore or cross-on. The energy stays low, between 48 and 164, but it’s all poor quality.
The first real standout of the whole period shows up on the morning of Saturday the 15th. The wind goes glassy again from the west at 3 mph, and the swell bumps up to 4ft from the NW, with an 8-second period. The energy is 169 (moderate), and the conditions are glassy. It’s “surfable waves but very ordinary conditions,” but the glassy wind makes it the best looking session so far. This is a morning mission for the dedicated.
Then, hold on to your board. The afternoon of Sunday the 16th is the true highlight. Wind is glassy from the west at 3 mph, and the swell jumps to 6ft from the NW. The period is short at 7 seconds, but the energy spikes to 317 (moderate to strong), and the forecast says “expect good surf conditions.” For a reef break, 6ft is solid. It’s well over the beginner mark, so this is for the advanced crew only. The short period means it might be a bit dumpy, but with glassy conditions, it’ll still be fun. This is the best session on offer – no question.
Monday the 17th morning is still glassy with 4ft from the NNW (194 energy), but it’s only “surfable waves.” The afternoon turns onshore and messy again. After that, the last few days of the outlook drop back into poor, small, and choppy conditions.
So, to sum it up: the first week is a write-off. The Friday the 7th morning is a tiny clean window but too small. The real standout is the afternoon of Sunday the 16th, with 6ft, glassy wind, and good energy. The morning of Saturday the 15th is a solid backup. For the rest, don’t bother.
Rusty.

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

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 Santa Maria de Oia 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.
