The Lowdown
Alright, let’s break this down. The forecast for Saint Annes is a tough one. It's a sheltered reef break that needs a WNW swell to work its magic, and looking ahead over the next sixteen days, things just aren't lining up. We’re looking at a long gap here with no decent surf. For a week straight, from Thursday the 27th of August right through to Wednesday the 2nd of September, it’s all poor surf conditions. The wave energy is either weak or moderate with a dodgy cross or cross-onshore breeze. The swell is often short-period and messy, or the direction is off.
The water temp is sitting at 60°, which is a bit colder than normal for this time of year. Not going to be a pleasant session even if the waves were good.
Things look a bit more promising starting on Thursday the 3rd of September. We get a pulse of swell from the SSW pushing 6ft with a moderate 14-second period, and the wave energy jumps right up (1345). But even then, it's only considered marginal due to questionable tide factors. The morning is light cross-onshore, and the afternoon is a gentle cross-shore, so it's not all bad.
The best bet in this entire run comes on Thursday the 3rd of September, afternoon session. You've got a 5ft SSW swell, still with that moderate 13-second period and strong energy (1243). The wind is a gentle cross-shore, so it'll be pretty clean. This is your standout window. It’s a far cry from perfect, but the cross-shore wind and that solid lump of energy from the south are the best combo you'll get. Keep in mind it’s a reef break, so bring your A-game.
After that, it fades back into marginal or poor surf for the rest of the second week. The SSW swell stays in the 2ft to 4ft range, and the winds are inconsistent, with some light onshore days and others with a moderate cross-shore. It’s not a total blank, but nothing else is worth shouting about.
Keep your eyes on that Thursday afternoon, September 3rd. That’s where it’s at. The rest of the time, you’re better off taking a long walk on the beach.

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.
