The Lowdown

G’day, I’m Rusty. Let’s be straight up — the next two weeks at Saint Annes are looking pretty grim. This is a sheltered reef break that really needs a clean WSW to WNW swell to get going, but the conditions just aren’t cooperating for paddle surfing. The whole run is a long stretch of poor to marginal surf, with the first real glimmer of anything worth getting wet for not showing up until Wednesday the 9th, and even that’s a struggle.

The first few days, from Sunday the 6th to Tuesday the 8th, are a write-off. Swell is tiny, between 1ft and 3ft, with a weak combined energy (434 down to 106), and the wind is all over the place — cross-on or cross, never clean. Not worth even looking at the water.

Things get a little more interesting Wednesday morning the 9th, when a long-period 19 second groundswell pushes through from the SSW at 2ft, with the combined energy jumping to 431. The wind goes light cross-on, but it’s still just “marginal” — the tide and swell are fighting each other. That same long-period pulse hangs around through Thursday the 10th morning with a bit more size (3ft) and stronger energy (744), and again light cross winds. These are the best two sessions of the whole outlook, but you’d want to be a local who knows the reef’s finicky tide windows. The water’s sitting at 62°, about average for this time of year.

From Thursday afternoon through the weekend of the 12th-13th, the swell shifts to a short-period 7-8 second WNW windswell, and the size jumps to 8ft on Saturday afternoon and again Sunday afternoon. The combined energy hits 933 and 1035, which is strong, but the wind is a fresh to moderate cross-shore, making it lumpy and messy. That’s too big for beginners and, with that short period and cross-wind, only a handful of experts would bother — and even then, it’s more likely to appeal to kite surfers looking for some punch in the windswell.

The second week drags on with similar story: Monday the 14th through Friday the 18th sees waist-to-chest high WNW swell, mostly 4ft to 6ft, but it’s all short-period windswell (7-11 seconds) with cross to cross-on breezes. The combined energy sits in the 500-700 range, which is moderate, but the quality just isn’t there. Nothing clean enough to call a standout.

Saturday the 19th and Sunday the 20th see a return of longer-period SSW groundswell (16-18 seconds) but at only 2ft to 3ft, and light onshore winds. That’s a tease — the period is there, but the size isn’t, and the reef needs more push.

Bottom line: the only two windows worth a look are Wednesday morning the 9th and Thursday morning the 10th, when that long SSW groundswell lines up with light winds. The rest is a long, flat, choppy stretch. If you’re a surfer, keep your eyes on the forecast for a change. It tends not to stay this poor forever. If you’re a kiter, there’s a bit of wind and swell mid-month that might get you interested.

Stay salty,
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.
