The Lowdown

Alright, surfers, Rusty here. Let's have a look at what's on the table for Saint Annes over the next couple of weeks.

Honestly, the outlook is a bit of a heartbreaker for this sheltered reef break. We're looking at a long, dry spell of poor conditions before anything worth paddling out for shows up. The water temp is sitting around 61° which is just a touch cooler than average for this time of year, but nothing to stress about.

The first real chance of a wave comes on the morning of Saturday the 5th of September. We've got a clean 4ft swell rolling in from the SSW with a very long period of 16 seconds. That's proper groundswell energy, and the combined energy is moderate (784). The wind is light and offshore from the SW, which should keep it glassy. But the report flags it as marginal due to tide, so it's a gamble. After that, we slide straight back into poor surf with onshore and cross-shore winds for days.

The next faint glimmer is on the morning of Wednesday the 9th of September. A 4ft SSW swell at 11 seconds is running, with light cross-shore winds from the NW. The energy is still moderate (668). It's flagged as marginal again, so not a stand-out.

Then, on the morning of Thursday the 10th of September, we see the strongest energy of the period so far. The swell is 3ft from the SSW with a very long 17-second period, and the combined energy is strong (1062). The wind is a gentle cross-shore from the NW. This is the best window for a surf, but it's still only a marginal call.

The pattern gets messy from there. The middle of the second week sees a lot of short-period, choppy WNW windswell piling in. By the morning of Sunday the 20th of September, things look interesting again. A clean 3ft swell from the SW with a super long 19-second period arrives, with a light offshore from the SSW. The energy is moderate (655). The afternoon then sees a jump to 8ft from the WNW, but that's a short-period windswell (7 seconds) and the energy gets strong (1152). That 8ft is getting into expert territory, especially at a reef break, and the period is too short for quality.

The absolute standout in this whole 16-day window is the Thursday morning of the 10th of September. The combination of that strong, long-period groundswell energy and the gentle cross-shore wind offers the cleanest, most powerful waves on offer. It's a genuine window for a session, but it's still a one-off in a sea of flat days. For the rest of the time, you're better off looking at other plans.

Rusty, signing off.

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.
