The Lowdown
Alright, let’s talk about the surf around here for the next sixteen days. It’s all about Santa Maria de Oia, a reef break that’s for the advanced crew only. It’s fairly consistent, but the wind and swell are all over the place. You’ll be waiting a while for something good.
The first real chance is on Thursday morning, the 27th of August. We’ve got a 5ft swell from the WSW, with a period of 8 seconds, and a light offshore wind from the SE. The combined energy is moderate (320). It’s clean, but the tide is a bit iffy, so you’ll need to time it right.
The standout of the whole forecast is Friday morning, the 28th of August. This is the one. The swell jumps to 7ft from the WNW, with a 10-second period, and the combined energy is strong at 810. The wind is a light cross-offshore from the SSW. It’s going to be very good. The water temperature is about average for the time of year. It’s a bit big for beginners, but for the advanced crew, this is the morning to be out.
After that, it’s mostly a write-off. The weekend of the 29th and 30th is small and choppy. There’s a long, dry spell of poor conditions through the first week of September, with moderate to fresh cross-onshore winds and choppy, lumpy seas. Not worth the effort.
Then, on Monday, the 7th of September, we get a flicker of hope. The morning shows a 5ft swell from the W with a very long period of 21 seconds, giving a massive 2639 combined energy. That’s a groundswell, and it’s powerful, but the wind is cross-onshore, so it’s marginal. The afternoon sees the swell hit 10ft from the WNW, with a 19-second period, and a huge 5698 combined energy. That’s for experts only, and the onshore wind will make it a lumpy, dangerous beast.
The following days see that swell drop, but the wind stays onshore, making it a write-off.
So, the pattern is clear: a long wait for a very brief window of quality. The only real standout is Friday morning, the 28th of August – that’s the one to circle. The rest is a test of patience.
