The Lowdown
Alright folks, Rusty here. Let’s get stuck into what’s coming our way for Saint Annes. Gotta be honest with you, it’s a bit of a slow start, but there’s a small window that’s worth setting the alarm for.
The first few days are a write-off, honestly. We’re looking at a long gap with no real surf on offer through Monday the 7th and Tuesday the 8th. The swell is small, the wind is mostly cross or cross-on, and it’s just messy. Not worth paddling out for.
Then, on Wednesday morning the 9th, things get interesting. The wind drops to glassy, and we’ve got a clean 2ft swell rolling in from the SSW. The combined energy is solid at 409 (moderate), and with a long period of 19 seconds, that’s a proper groundswell. This is the standout of the whole forecast. It’s a reef break here, and that long period will wrap in nicely. The water temp is about average for this time of year, so a spring suit will do. Expect clean, glassy faces. It’s small, but for the advanced surfer, it’ll be the best we see.
After that morning, the wind swings around and gets a bit cross-on, so the quality drops right off. The rest of Wednesday and through to the end of the week is just poor surf conditions. The swell tries to pick up a bit around Saturday the 12th, with a 7ft WNW swell, but the period is short at 7 seconds and the wind is moderate. It’s going to be a choppy, cross-shore mess. That’s more of a kite day than a paddle day.
Sunday the 13th shows a bigger 8ft WNW swell, but again, it’s short-period and cross-shore, so it’s marginal and only for the experts if they’re desperate. The energy is high at 949 (strong), but the quality just isn’t there.
The second week is a bit of a tease. From Monday the 16th onwards, we see a return of some longer-period SSW swell, but the wind is mostly cross-on and the conditions are “poor” or “marginal.” There’s a few mornings with light breeze and a 3ft to 3ft SSW swell, but it’s never quite clean enough to get excited about. The combined energy stays moderate to strong (342 to 824), but the wind just won’t cooperate for a proper session.
So, bottom line: if you’ve got a free Wednesday morning the 9th, get down to Saint Annes for that glassy, long-period SSW groundswell. It’s the only real standout in the whole 16 days. The rest is a waiting game.
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.
