The Lowdown
Alright, Rusty here again. Let’s run through it in feet and Fahrenheit.
We’re looking at a slow start with tiny, weak surf. There’s a slim chance of a clean wave Saturday the 12th morning. The swell is only 2ft from the WNW, but with light cross-offshore wind, it’s rideable. The water temp is 65°, pretty average for now.
Sunday the 13th morning is where it gets real. That NW swell jumps to 4ft with a long period of 12 seconds – proper groundswell. The energy is moderate at 532. Light cross-offshore wind keeps it clean. This is a reef break for advanced surfers only.
Monday the 14th morning is dead glassy with about 3ft of NW swell. Small and clean, nothing heavy.
Things go bad from Tuesday the 15th through the end of the week. Strong winds ruin the shape. Midweek has 5ft of short-period junk – more for kite surfers than anyone on a surfboard.
The big standout is Monday the 21st of September. We get a solid 5ft of NW groundswell with a 13-second period. The wind is light and cross-offshore in the morning, turning glassy in the afternoon. The combined energy is high at 871. Clean, powerful, and lined up. Best session of the whole stretch.
Tuesday the 22nd and Wednesday the 23rd mornings stay glassy, but the swell drops back to about 4ft and 4ft respectively. Still good, just not as strong.
After that it fades. End of the month brings cross-onshore wind and a 17-second period swell that’ll probably break too straight for this reef. Not worth the paddle.
Rusty out.

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.
