The Lowdown

Right, gather 'round me cobbers, ol' Rusty here with the brutal truth for Saint Annes. We're lookin' at the next couple of weeks and, to be straight with ya, it's a bit of a tough watch for a while. There's no real surf on the cards to start, and we've got a long, quiet gap stretching from now, the 4th of September, all the way through to the 9th. Swell energy is weak, real weak, with readings between 105 and 971 – not enough grunt to get excited about. The wind's been a nuisance, mostly cross-onshore, keeping the surface all choppy and messy. We ain't seein' any standout sessions in that first week, I'm afraid.

Now, we start to see a shift on the 9th of September (Wednesday). The swell direction swings around to the SSW, and while the height is only about 4ft to 3ft, the period drops to 11 seconds, which is a bit short, ya know? More importantly, we get a clean nor-norwest cross-offshore breeze in the afternoon. That cleans things right up. It's still not epic, but it's the first time the ocean looks half-decent for a paddle. The wave energy is still only moderate (617-748), so don't expect bombs, but it's a start.

The only real spark in this whole forecast is on Thursday the 10th of September. Now, look, it's still "marginal" in the books, but we get a solid push of swell. Thursday afternoon sees the swell jump to a legit 8ft from the south-southwest. That's a big number for this sheltered reef. The period is short, just 10 seconds, which means it'll be fat and powerful, not the kind of wave you wanna be on if you're still finding your feet. An 8ft day like that, with a light southerly wind, is firing for the experienced lads and lasses. The combined energy reading of 2932 tells ya there's proper power in the water. High tide will be a factor here, but for the crew who know this wave, Thursday afternoon is *the* one to circle. Just keep an eye on the crowds, 'cause it's a break that can get "often" busy.

After that, things go a bit sideways again. Friday the 11th gets hammered by a fresh 19 mph southerly wind, turning the ocean into a lumpy mess for the morning, and it stays choppy all day. The swell drops right back down to under 3ft. The pattern for the next week is a real mixed bag of small windswell – a few pulses from the WNW with periods as short as 6 or 7 seconds. Those are just wind-chop waves. If you're a kiter, that WNW 6ft on Monday 14th or 6ft on Thursday 17th might look fun with that cross-breeze, but for a surfer, it's just weak, bumpy, and unappealing.

Lookin' way down the track, there's a late flash on Friday the 18th of September. Another big one pops up: 10ft from the WNW. That's a seriously heavy number, but it's on a short, weak 8-second period, so again, it's a powerful, fat wall of water. And with all the prior small days, the forecast for that one is a long way out and not super reliable. It's a tease for the future.

So, to sum it up: the first week is a write-off. The one and only standout is Thursday the 10th of September at Saint Annes itself – a big, powerful SSW swell for the advanced crew. It's the only time the ocean really shows its teeth. Other than that, you're lookin' at a lot of small, choppy days and some wind-swell junk. Keep an eye on that Friday 18th in the distance, but don't hold your breath.

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. 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.
