The Lowdown
Alright, let’s get into it.
To be honest, the next couple of weeks look pretty forgettable for Saint Annes. We’re looking at a long stretch of small, onshore wind-affected surf. The models are showing waves, sure, but they’re mostly short-period windswell with a lot of west in the wind, which is going to leave things messy and lumpy. There’s no real punch to anything on the horizon, and the window is pretty much a write-off for any quality sessions.
The first real surf we see is Saturday morning, the 8th. It’s a small one, about 3ft of SSW swell with a long 18-second period. The energy is weak at 429, and the light cross-on wind is just enough to put a bit of texture on it. It’s rideable, but you’d be scratching for anything clean. The water temp is sitting right around average for this time of year, so no surprises there.
That trend holds through Sunday and Monday. The swell stays around that 3ft to 3ft mark, but the period drops and the wind swings straight onshore from the SW. The energy stays moderate but it’s not doing us any favors. Honestly, the conditions are just poor for any kind of decent peak.
Things get a little more interesting mid-week, but not in a good way. The swell stays small, but the combined energy starts to climb a bit. The period stays long, mostly in that 15-19 second range, but the wind keeps ruining the surface. It’s all onshore and cross-onshore, so don’t expect any glass.
As we head into the second week, the pattern stays pretty locked in. The wind picks up a touch, with a cross-shore component that adds some chop. The swell size stays in that 2ft to 3ft range, but the period drops out, meaning it’s just mushy, unorganized lines. The energy numbers fluctuate, even hitting a 940 on Wednesday morning, but it’s all messy and blown out. There’s a brief jump on Wednesday afternoon with a 6ft WNW swell, but the period is a short 7 seconds and the wind is going to chop it to bits. That’s not for paddling, that’s more of a kite-surfing setup if anything.
The final weekend and into the start of the next week doesn't offer any redemption. Swell stays small, the period is short, and the wind is just enough to keep it bumpy. There are a couple of days with a bit more size, around 4ft to 4ft, but again, the period is short, so it’s going to be walled up and closed out at this reef.
So, if you’re desperate, the best bet is probably that first Saturday morning, the 8th. It’s small, but the long period means there’s a bit of push, and the light wind is the cleanest we’ll see. But don’t get your hopes up. This is a blank run for the most part, which is a normal thing for this spot. We just got to wait for the ocean to wake up.
Keep an eye on it, though. Forecasts can change.

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.
