The Lowdown
G’day, Rusty here, lookin’ at the Saint Annes picture (reef break). Truth is, mate, this 16-day window is a bit of a rough one. We’ve got a long stretch of poor conditions to get through, but there’s a little window of hope halfway through the first week of September that’s the real standout.
The whole period starts quiet and messy. From Sunday the 30th of August, right through to Friday the 4th of September, it’s a string of days with weak, cross-shore wind and small, short-period swell. The energy is all over the place, but it’s low to moderate at best, with values between 213 and 1199. The water’s about average for this time of year, nothing unusual. For a spot that’s fairly consistent and sheltered from the WNW, the wind is just killing it. Keep the stick in the car for this run.
The first real sign of life shows up on Sunday the 6th of September. Overnight, the wind swings around to a light cross-offshore from the north, and we get a clean-up. The swell holds at 3 ft from the SSW with a long 15-second period, giving it some grunt. The combined energy reads 458, which is moderate, but the clean conditions make it the pick of the bunch. This is a morning session for sure, with that light breeze and clean surface. The SSW direction is a bit off the optimum WNW, but when it’s glassy like this, you take it.
Monday the 7th of September morning is a bonus. The wind drops to glassy, near flat calm, with light air. The swell is 3 ft from the SSW, period 14 seconds, and the energy is 312. The waves are small and ordinary, but that glassy surface makes it surfable for a quiet paddle. The crowd factor is often here, so you might have a few mates out, but it’s a small-wave day.
After that, it’s back to the doldrums. From Tuesday the 8th of September through to Thursday the 10th, the swell drops right off to 1 ft to 3 ft, with messy cross-on winds and low energy readings between 110 and 669. Not worth a look.
The second week gets a bit weird. Friday the 11th of September afternoon sees a jump in swell height to 7 ft, but it’s from the WNW with a short, choppy 6-second period. The energy is moderate at 543, but the period is so short it’ll be a wash. This is a poor, bumpy mess. Saturday the 12th and Sunday the 13th of September see the swell build to 8 ft from the WNW, with 8-second periods. The energy on Sunday afternoon hits 1039, which is strong. But that’s a lot of water for a reef break with a cross-shore wind. The WNW direction is spot-on for the optimum, but the period is short, so it’s going to be a lumpy, hard-to-handle wave. This is only for experts, and the wind is still cross, so the quality is marginal. It’s a solid, powerful swell, but the conditions are too rough to call it a standout.
The best of the whole outlook is unarguably Sunday the 6th of September morning. Clean, light cross-offshore wind, a consistent 3 ft SSW swell with a long 15-second period, and moderate energy. It’s the one to pencil in.
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.
