The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Saint Annes.
Straight up, the next couple of weeks are a bit of a mixed bag. We’ve got swell on the cards, but the wind and conditions are going to be the main story. There’s a lot of chop and cross-shore wind messing things up, so it’s not going to be clean and glassy every day. We’re looking at a long stretch of mediocre to poor conditions, with only a few windows where things line up.
The water temp is sitting at 63°F currently, which is about normal for this time of year – nothing unusual there.
This first week is a tough one. Thursday morning (10th September) sees some small SSW swell around 3ft with a long 17-second period, giving a moderate wave energy (672). But the wind is cross-shore from the WNW at 15 km/h, creating a slight cross-chop. It’s a marginal call, and the score is low. Thursday afternoon is worse, with the wind picking up to 20 km/h and the swell shifting to SW at 3ft, period 16 seconds. The wave energy is a bit higher (752), but the conditions are poor. Friday and Saturday follow the same pattern – small swell, but the wind stays cross or cross-onshore, keeping the surface messy. The swell does start to build a bit; Saturday afternoon sees a shorter period WNW swell of 6ft with a weak 7-second period, but the cross-shore wind is up to 25 km/h, creating a lumpy cross-chop. That’s not a fun paddle.
Sunday (13th September) is a real kicker. The swell is 8ft from the WNW, but the period is a short 8 seconds. The wind is howling from the NW at 35 km/h, and the wave energy is very strong (863). This is a big, raw, messy ocean. It’s expert-only territory, and even then, it’s going to be a battle. The break is a reef, so it can handle the size, but the wind is just going to tear it apart. This is honestly more interesting for kite surfing than paddle surfing.
Monday (14th September) and Tuesday (15th September) are a slight improvement. The swell drops to 5ft to 6ft from the WNW, with a period of 9 seconds. The wind is lighter, 10 to 15 km/h, but it’s cross-on or cross-shore, still not clean. These are marginal days, with a slight trace of chop.
Then we hit a real lull. From Wednesday (16th September) through to Sunday (20th September), the swell drops right off, down to 2ft to 3ft. The wind is mostly light, but it’s cross-shore or cross-on, and the wave energy is low (264 to 683). The conditions are poor, with no real surf to speak of. It’s a flat spell.
Now, here’s the one standout in the whole forecast. It’s a bit of a way off, but look at Tuesday (22nd September). We’ve got a SW swell of 3ft with a 16-second period, and the wave energy is solid (706). The wind? It’s going to go glassy in the afternoon. That’s right, glassy. WSW wind at 5 km/h, with the wave comment saying “glassy”. This is the window. The swell is small, but it’s a long-period groundswell, which is great for a reef break like Saint Annes. The wind is dead calm, so the surface will be like a mirror. It’s a small swell, but for a clean, glassy session, this is the best of the lot. It’s a promising one, but it’s a week and a half away, so keep an eye on it.
Wednesday (23rd September) and Thursday (24th September) see the wind shift back to cross-on, and the swell drops again, ending the run on a flat note on Friday (25th September) with a tiny 2ft SW swell.
So, the best on offer is Tuesday 22nd September afternoon. It’s the only time the wind truly goes glassy. The rest of the period is a write-off due to wind or flatness. Stay patient.
Rusty.

Information about the Saint Annes Surf forecast
The above surf forecast table for Saint Annes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Saint Annes can be found by selecting the local surf guide option on the grey menu. Our Saint Annes 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 (Saint Annes) 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 Saint Annes 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.
Saint Annes is 4 km (2 miles) from Port San Luis. If you plan a vacation in San Luis Obispo, look for hotels and other accommodation in Port San Luis. Port San Luis has rooms for a wide range of budgets as well as car hire and transport links.
