The Lowdown
Alright, Rusty here. Let's break down what we've got for the next couple of weeks at Saint Annes. It's a sheltered reef break that likes the swell from the WNW. The water's running a touch warmer than normal for this time of year, about 65°, so not a bad thing.
Right off the bat, it's a bit sad. We've got pretty much the first week, from Saturday the 12th right through to the end of the week, where conditions are just poor. The swell is small, the wind is messy and cross-shore, and it's just not giving us anything to work with. You’re looking at a solid gap of seven days or so where I wouldn’t bother paddling out unless you just want to float.
The first real glimmer of hope shows up on Monday the 14th with a marginal call. We've got a 6 ft swell from the WNW with a short 8-second period, but the wind is light. The combined energy is moderate at 794, but those short-period waves just don't have the push. It's a "maybe if you're desperate" kind of deal, but not what I'd drive for.
The best of what we’ve got, and I'm using that word loosely, looks like it's going to be around Tuesday the 23rd of September. The morning is showing a clean 4 ft swell from the WNW at 10 seconds (699 energy) with a light offshore from the SW, which is the ideal direction for this spot. The afternoon picks up a bit to 5 ft from the same direction, with a longer 13-second period and good energy at 945, and again we have light cross-onshore wind. That longer period should give the reef a bit more shape. Those two sessions are the true standouts, but they’re still only marginal surf due to questionable tides and general conditions, so keep your expectations in check. The crowds are always an issue here, so expect to share the water.
After that, the swell fades back into the small stuff and the wind turns messy again for the rest of the outlook.
So, to be honest, the pickings are slim. If you're dead set on getting wet, target the 23rd when the wind is clean for Saint Annes. Otherwise, you might want to leave the board in the van for a while.
Rusty.

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.
