The Lowdown
Alright, grab a coffee and listen up. Honestly, the next couple of weeks are looking pretty average for Saint Annes. It's a tricky spot, a sheltered reef that needs the right direction, and for most of this run, we just aren't getting it.
The 29th of August kicks things off with a solid long-period swell (17 seconds) pushing in from the SSW, generating moderate wave energy (984). The problem is the wind. We’ve got a solid 20 km/h WNW breeze blowing straight across the break, which is turning the ocean into a mess of cross-chop. The water temp is about what you’d expect for this time of year, so no surprises there. Saturday morning is a write-off, and the afternoon is only marginally better. We see the same story on the 30th – similar swell but the same cross-shore wind, leaving the ocean chopped up. Sunday, the 31st, the wind drops a little, but it's cross-onshore, which is still a bit of a downer, with small weak ripples on the face. The swell is dropping too, down to 3 ft. It stays pretty flat and onshore through the start of September.
The only glimmer in this whole 16-day forecast comes on the 7th of September. Monday morning gives us a short window of glory. The swell is a modest 3 ft from the SSW, but the wind goes completely glassy – a light breeze from the SW, which is as close to perfect as you can get at a cross-reef. The energy is weak (406), but the conditions will be clean. This is the standout. It’s the only time in the whole run we get that "glassy" label. After that, the wind swings around onshore again and the swell drops off, with the 8th of September seeing a tiny 1 ft northwesterly swell (37) that’s barely a ripple.
The 9th of September shows a bit of a pulse with a very long period (19 seconds) SW swell, but it’s small at 2 ft and the wind is on it. Later in the second week, the 10th and 11th of September see a bit more size at 3 ft, but the wind is howling at 25–30 km/h from the NW, just making it lumpy and ugly. There’s nothing to get excited about.
Bottom line: If you're desperate, set your alarm for the 7th of September. That morning is your only real chance at a clean, glassy session. The rest of the run is a waiting game.

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.
