The Lowdown
Right then, let’s have a look at what’s on the cards.
Alright, for the next few weeks, Saint Annes is your only play, and I’ve got to be straight with you – it’s a bit of a mixed bag. We’ve got a few decent windows, but there’s plenty of flat, blown-out days to wade through as well. Water temp is sitting at 63°, which is about normal for the time of year.
The first real standout comes on Monday the 14th of September. The morning session is the one to aim for. We’ve got a clean 6ft swell rolling in from the WNW with a period of 8 seconds. The combined energy is moderate at 867. What makes this one special is the wind – a nice 9 mph cross-off breeze from the NW, meaning it’ll be glassy and groomed. This is advanced-level reef break stuff, and it’s fairly consistent, so you should get a few. Be aware, crowds are likely here. The afternoon goes a bit wobbly, so make the most of the morning.
After that, things drop off hard. Tuesday the 15th and Wednesday the 16th see the swell fade to nothing much, with onshore winds and questionable conditions. There’s a long gap from Monday afternoon right through until the morning of Sunday the 20th where there’s nothing worth paddling out for – just small, weak energy and poor surf.
We do get a bit of a tease from Sunday the 20th of September through to Tuesday the 22nd, with knee-to-waist high swell from the SW, but it’s marginal at best. Light cross-onshore winds will keep it a bit lumpy. It’s not going to blow your mind, but if you’re desperate, you might find a grovelly one. The energy stays weak through this period, mostly between 400 and 600.
The next real highlight, and the best on offer for the whole run, is on Sunday the 27th of September. This one is a promise, but it’s a long way out, so keep an eye on the charts. The morning sees a solid 7ft swell from the NW, with the combined energy jumping up to a strong 1226. That’s serious power. The period is short at 8 seconds, but with a light onshore wind, it might be a bit lumpy. The afternoon cleans up a bit with a cross-shore, but the swell bumps to 8ft. That’s big for this reef – definitely expert territory only. If it lines up, it’ll be a beast.
After that, Monday the 28th and Tuesday the 29th still have some size (6ft to 7ft) but the wind turns messy again. The energy stays in the moderate to strong range, but the quality won’t be there.
So to sum it up: you’ve got two proper windows. Monday the 14th morning is the clear, clean standout for this week. And Sunday the 27th is the big, powerful one for the experts to pencil in. Everything else is a bit of a write-off.

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.
