The Lowdown
G’day, Rusty here. Look, I’ll level with you—this stretch from August 25 right through to September 9 is a tough watch. If you’re chomping at the bit for a proper surf, you’re gonna be waiting a while. There’s no standout day to circle on the calendar where everything clicks, just a long run of messy, cross-shore chop and poor conditions. The first solid window doesn’t even show up until Thursday morning, August 27, and even then it's a marginal call.
The only break on the cards is Saint Annes, a sheltered reef that likes a WNW swell. The water temp anomaly is about average for this time of year, so nothing unusual there. It’s fairly consistent as a spot, but crowds are often an issue here.
Now, the closest thing to a highlight is the morning of Thursday, August 27. Swell is 6ft, coming from the WNW with a period of 8 seconds—short period, so it’s a bit of a windswell, not a clean groundswell. Combined swell energy is moderate (597). Wind is light and cross-shore at 6 mph, meaning small crossing wind ripples but not too choppy. It’s borderline, and you’ll be fighting tide questions. Still, it’s the best of a very average run.
Friday morning, August 28 offers a similar story: 3ft from the SSW with a very long 19-second period. That’s a proper groundswell, but at a sheltered reef, that long period might make it fat and straight. Combined energy is moderate (636). Wind is light cross-shore. It’s another marginal one, but don’t expect much.
After that, it’s a grind. From August 29 through early September, you’re looking at cross-shore winds of 9–16 mph and poor to marginal surf. The swell hangs between 2ft and 4ft, mostly from the SSW with moderate to strong combined energy, but the wind just won’t line up cleanly.
The one curveball is Monday afternoon, August 31—a 7ft pulse from the WNW with a short 7-second period. That’s too big and sloppy for beginners, and with cross-shore breeze at 16 mph, it’s going to be a mess. More of a kite-surfing setup than a paddle day.
Later in the week, Monday afternoon, September 7 shows a 8ft WNW swell with a 7-second period and gentle cross-shore wind. That’s expert territory size-wise, but with that period and wind, it’s not going to be clean.
So, the honest truth? There’s no real standout here. If you absolutely have to paddle, Thursday morning August 27 or Friday morning August 28 are your best bets—but keep expectations low. This is a rare blank run for the area, and it tends not to stay this poor for long. Forecasts can change, but right now, I’d say give it a miss.
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.
