The Lowdown

Alright, let's talk about Saint Annes for the next couple of weeks. I've got to be honest with you, it’s looking pretty grim. This reef spot is sheltered, and it needs everything to line up perfectly, which just isn’t happening.

We get a little bit of long-period groundswell from the SSW starting August 18th and 19th, with wave heights around 3 ft and a period of 15 to 16 seconds. The swell energy is moderate, sitting in the 482 to 728 range. But the wind is blowing cross or cross-onshore, and the surf is being called "poor". That means the face is a mess, which is the last thing you want on a reef. The water is about normal for this time of year at 63°F.

From August 20th all the way through the 29th, we get a series of short-period, 6 to 8 second WNW swells. Heights bounce between 1 ft and 7 ft. But again, the wind is always cross or cross-onshore, and the surf quality stays "poor". It’s just sloppy, choppy water for a solid week and a half. When the swell is short-period like that, the waves just don't have any shape.

The biggest energy we see is on August 28th with a 7 ft swell and combined energy of 785, but the wind is a steady 16 miles per hour and cross-shore, making it a lumpy, choppy disaster. Anything over 5 ft in these windy conditions is for the experienced crew only, and honestly, it looks like better conditions for a kite than a surfboard.

The first few days of September don't change the tune. There's more "marginal" and "poor" surf with cross-shore winds. The best energy of the whole 16 days pops up on September 2nd afternoon – a 8 ft WNW swell with a combined energy of 812. But with 9 miles per hour of wind and "marginal" conditions, it's just a case of what could have been.

To be blunt, there is not one single session in this entire 16-day window that I’d recommend packing a board for. It’s a long, dry spell for Saint Annes. Leave the board at home and hope the next forecast looks better.

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.
