The Lowdown
Alright folks, Rusty here. Let's talk about what's on the menu at Saint Annes over the next couple of weeks.
First off, I gotta be straight with you – it's a tough stretch ahead. We've got a long dry spell to kick things off. From now through the 11th of September, the surf is pretty much a write-off. The waves are small and weak, and the wind is almost always coming from the wrong direction, putting a nasty cross or cross-onshore chop on the surface. The swell energy is weak to moderate at best, and the period is all over the place, but it doesn't matter because the conditions are just poor. There are a few sessions here and there with clean conditions on the 9th Wednesday morning, but the waves are tiny at 2ft from the SSW with a 19-second period, and the energy is still moderate. It's not worth paddling out for.
Things get a bit more interesting around the 12th of September, Saturday. We see a bump in size with waves hitting 6ft in the morning and pushing 8ft by the afternoon, all from the WNW. But the period is a short, weak 8 seconds and the energy is strong. The problem is the wind is a moderate cross-shore, so it'll be a lumpy, choppy mess. That kind of size with that short period and wind is more of a kite-surfing setup than a paddle surfer's dream. It's a pass for me.
After that, from the 13th to the 21st of September, we're back to a grind. The waves stay small, mostly between 1ft and 6ft, with weak to moderate energy. The wind is mostly light cross-onshore or cross, which doesn't help. There are a couple of mornings, like the 17th Thursday and 19th Saturday, where the conditions are described as "marginal," but the waves are still tiny (2ft to 3ft). The only real standout is a brief window on the morning of Wednesday, 18th September. We've got 6ft from the WNW with a short 6-second period, but the wind is a light cross-shore, so it might clean up a bit. The energy is strong, but it's a short-period swell, so it'll be a bit fat and weak for the size. It's the best of a bad bunch, but honestly, I'd keep your expectations low. There's nothing here that gets me excited.
So, the bottom line? We're looking at a 16-day forecast with very little to recommend. The first 11 days are a bust, and the second week only offers one day (18th September) that's barely worth a look. The setup here is sheltered and needs a specific swell direction (WNW is the optimum), and we just aren't getting the right combination. It's a tough run, but that's how it goes sometimes.
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.
