The Lowdown
Alright crew, Rusty here. Let’s take a look at what’s shaping up for Saint Annes over the next couple of weeks.
Honestly, for a solid stretch here, it’s looking pretty grim. We’ve got a long, quiet run with barely anything to get excited about. The water is sitting at 60°, which is a touch cooler than average for this time of year (anomaly of 2°F colder), so you’ll want a decent wetsuit if you’re paddling out.
The first real chance of anything worthwhile doesn’t pop up until Saturday, September 12th. Even then, it’s a tricky one. That morning we see a pulse of 5ft swell coming from the WNW, but with a short, crumbly period of only 7 seconds. That’s windswell, not groundswell, so it’ll be fat and lack punch. The combined energy is moderate (533). Winds are light and cross-onshore, which won’t help clean it up. It’s marginal at best, and really only for someone desperate for a splash.
The standout, if you can call it that, comes on Sunday, September 13th. The afternoon sees a jump in size to 8ft from the WNW, still with that short 7-second period. The energy ramps up to moderate (665), but that size with that period is gonna be a bit of a washing machine – fat, walled up, and hard to get into. Winds are light and cross-onshore, so it’ll be lumpy. This is expert territory only at that size, and the break is a sheltered reef so it might focus the energy a bit, but don’t expect any sort of classic reel.
Crowds are *often* here, but with this quality, you might have it to yourself anyway. Periods this short mean the swell won’t wrap in cleanly, and a reef break might feel a bit fat and frustrating.
So, there you have it. A quiet outlook with a couple of days offering something that’s more about being out there than scoring epic waves. The first week is a total write-off. The second week holds a promise that’s more about hope than expectation. Keep an eye on it, but don’t rearrange your schedule.
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.
