The Lowdown
Alright, surfers, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty grim for a proper paddle. We’re looking at a long stretch of small, short-period swell and wind that just won’t get out of our faces. It’s the kind of forecast that has you checking your gear for dust.
We’ve got a solid 16-day window, but the truth is there’s a big gap of nothing good at the start. For the first several days, from the 11th through the 13th, it’s really not worth suiting up. We’re talking ankle-biters and poor conditions. The energy is there, between 204 and 500 combined, but it’s messy and not doing anything for us.
Things get a little more interesting towards the end of the first week, but it’s all still marginal. It’s not until the 15th and 16th that we see the swell nudge up to around 3ft to 4ft, but the period is a short 15-16 seconds from the SSW. The wind stays cross-on, which is going to put some chop on it. Not clean, not powerful. Just average.
Now, for the one spot that’s on the map, the only game in town is Saint Annes (Saint-Annes). It’s a sheltered reef break, which is a blessing with this wind. But the problem isn't the break, it's the swell. It’s just not lining up. The energy in the water gets close to 640 on the 15th and 16th, which is moderate, but it’s all this short-period stuff. Don't get too excited.
The low point is that the winds stay stubbornly cross-on or cross-shore for the entire run. We do see a bit of a bump in the swell around the 22nd, with a 4ft pulse, but it’s coming from the WNW with a laughable 5-second period. That’s just wind chop, not surf. It’s more interesting for the kite crowd than for us.
After that, the swell fades back down to under 3ft and we’re back to square one. The water temp at the start is a fairly normal 64°F, which is about average for this time of year, so at least it won't be freezing when you’re sitting there staring at flatness.
Honestly, my call is to keep the board in the car for the first week. There’s nothing that’s going to be worth the paddle out. The cleanest conditions might be on the 15th or 16th if the wind drops, but even then, it’s a long shot. This is a blank run, plain and simple. Forecasts can change though, so don’t write the whole window off just yet.
Rusty, out.

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.
