The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Saint Annes over the next couple of weeks.
Straight up, this is a tough stretch. We've got a long dry spell ahead with very little to get excited about. The first solid recommendation doesn't pop up until the afternoon of Sunday, the 6th of September, so you're looking at over a week of flat or messy conditions before that.
Saint Annes is a sheltered reef break that lights up best with a WNW swell, but we've got a persistent run of weak, short-period SSW swell and cross or cross-onshore winds that are just ruining the shape. The water is sitting around 60°, which is a bit colder than normal for this time of year—about a degree and a half off the average, so you'll want the thick rubber.
The only true standout in the whole 16-day window is the afternoon of Sunday, the 6th of September. We've got a clean 3ft SSW groundswell with a long 15-second period, and the wind goes glassy. That combination is a rare treat here and will give you the best chance at a smooth, lined-up wave. Combined swell energy is moderate at 437, and for this spot, that's about as good as it gets in this outlook. Get on it if you can.
Before that, there's nothing doing. The early part of September is just a write-off—cross-onshore breeze, small weak swell, and poor surf conditions across the board. Even the marginal calls on the 4th and 5th are more hope than reality with the wind angles we're seeing.
Later in the second week, around the 12th and 13th of September, the swell picks up to 6ft to 7ft from the WNW, which is the right direction for Saint Annes. But the period is short (7 to 9 seconds), and it's looking lumpy and cross-onshore. The energy is moderate to strong (533 to 903), but for paddle surfing, the quality is a question mark. Honestly, with that size and wind setup, it might be more interesting for the kite crew than us wave riders.
Around the 14th of September, we've got similar size but still that onshore component. It could be worth a look if you're desperate, but I wouldn't call it a standout.
So, to wrap it up: if you've got a window, target that glassy Sunday afternoon on the 6th. Everything else, you're probably better off waiting for the next proper swell.
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.

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.
