The Lowdown
Alright, Rusty here. Let’s talk about what we’ve got on the table for Saint Annes over the next couple of weeks. Straight up, you’re looking at a very long, quiet stretch with barely a whisper of surf. The opening days through to the end of the first week have wave energy, but it’s all a bit jumbled and rough – not the kind of stuff that gets you paddling out with a grin. The wind is mostly cross or cross-onshore, keeping everything messy. There’s a bit of a pulse showing up around September 11th though, so let’s hold onto that.
Water temps are sitting at 60.4°, which is about 2° colder than average for this time of year. That’s a notable chill, so you’ll want the thick rubber if you’re heading in.
For the first week plus, from Thursday the 3rd through to around Wednesday the 9th, we’ve got small, weak swell and poor conditions. Expect heights hanging around 2 ft to 3.6 ft, but the wind’s never really clean – it’s mostly cross or cross-onshore, with a bit of a chop on it. The combined energy sits between 430 and 986 (moderate to strong), but it’s all wasted because the surface is so lumpy. Not much to get excited about here, folks. There’s a long gap of several days with no real quality windows.
Now, over onto Friday the 11th of September, we finally see something that raises an eyebrow. The morning brings a solid 6.2 ft swell from the West-Southwest with a period of 12 seconds, and the combined energy jumps way up to 1499 – that’s strong energy for the reef. But here’s the catch: the wind is from the Northwest at 9 mph, which is a cross-shore breeze, keeping it on the choppy side of messy. It’s marginal, better for advanced surfers who can handle a bit of texture. By the afternoon, the swell drops a touch to 5.2 ft, but the wind kicks up to 19 mph from the same direction, making a real mess of things. The other days around this are small or windy again.
As we head into the third week, around the 16th to the 18th of September, we get more of the same – small waves, mostly 2 ft to 3 ft, with light winds but still mostly cross-onshore or onshore. The 18th of September shows a glimmer with a long-period 20-second swell at 2.3 ft from the South-Southwest, energy at 614, but it’s still marginal. Nothing here that’s a firm standout.
So, if you had to pick the best of a quiet period, it’s that Friday morning on the 11th of September. The swell size is decent for a more experienced crew, with a moderate period shape, but the wind isn’t doing us any favours for perfect conditions. The reef at Saint Annes is sheltered and needs that optimum West-Northwest swell direction, and this swell is coming from the West-Southwest – not quite the sweet spot. It’s not the classic day you’d mark on the calendar, but it’s the only pulse that’s got any real push.
Crowds? They’re often here, so don’t expect solitude even if the waves are average.

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.
