The Lowdown

Right, Rusty here again. Let’s talk about Saint Annes in feet and degrees.

Water’s running at 63°F, pretty much what you’d expect for this time of year.

Truth is, it’s a bleak outlook for the most part. For the first week and a half, you’re looking at dribbly little waves. Swell heights from about 2ft to 5ft, mostly from the WNW or SSW, with short or very long periods, but the wind is all wrong. It’s cross or onshore almost daily, keeping the surface choppy and the shape ruined. Wave energy sits in the moderate range, between 300 and 500, but that means nothing when the wind’s trashing it.

There’s a real dry spell from Tuesday 15th right through to Tuesday 22nd September. Hardly a single session worth getting wet for.

The one and only gem in the rough is Wednesday 23rd September. Come morning, you’ll find glassy perfection with a light onshore breeze from the SW turning into a light offshore. The swell is a clean 3ft groundswell from the SW, with a 15-second period, pumping right into the optimum WNW direction at this reef. The combined energy is moderate at 563. This is a true stand-out for advanced surfers. Expect clean, lined-up waves, and because the conditions are that good, you can bet the crowds will be there too.

After that morning, the whole thing fades into small, bumpy leftovers for the rest of the month. Set your alarm for the 23rd.

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.
