The Lowdown
Right, let’s have a look at what’s on the cards for you here in the local zone.
To be straight with you, the next week is pretty grim. We’re looking at a long stretch of poor surf conditions right through until at least Thursday the 27th. The winds are mainly cross or cross-on, which is just knackering the waves. There’s a bit of a tease on the morning of the 27th with a small 4ft cross swell from the WNW, but it’s got a short period of only 7 seconds, so it’s not going to have any real push. The combined energy is still moderate at 422, but the forecast calls it marginal, and you’d be scratching around for a rideable one.
The real standout, and the only time I’d seriously consider paddling out, is the morning of Saturday the 5th of September. That’s a full 12 days away, so keep it in the back of your mind as a promising prospect rather than a locked-in call. Saint Annes (a reef break, sheltered from a lot of the junk) should be picking up a clean SSW swell. We’re looking at head-high waves at 4ft with a decent period of 16 seconds – that’s proper groundswell energy. The winds are light and cross-on from the west at 6 mph, which means the surface will be manageable. The combined swell energy is strong at 1498. It’s rated for advanced surfers only, and it’s a fairly consistent break, so there should be sets coming through. Because it’s a reef setup, that long-period groundswell should wrap in nicely rather than just closing out. You’ll want to be on your game.
Water temp is about average for this time of year, so no nasty surprises. Just keep an eye on that long-range forecast, as things can shift.

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.
