The Lowdown

Alright, let’s get into it.

The next couple of weeks are looking pretty frustrating, if I'm being honest. We’ve got a window here that’s mostly flat and junky, with only a few spots that even have a pulse. The key is gonna be picking your moments, because there are some long gaps where you won't want to bother paddling out.

Let’s start with the first real chance, which is Saturday the 15th. It’s not much, but it’s something. Saint Annes is showing a small 3ft SSW swell with a 16-second period. There’s a bit of life in that water, the combined energy is moderate at 611, but that wind is cross-on from the WSW at 6 mph, which is gonna put a few ripples on the face. The water temp is 64°, which is a touch warmer than normal for this time of year, so it won't be a shock to the system. It's a marginal call, though; the tide and that onshore angle are going to make it tricky. It's a reef break that’s fairly consistent, but it's also sheltered, so that small swell isn’t going to have a lot of push. You might get a few, but don’t expect any miracles. That afternoon, it drops off, and we’re left with "poor" conditions as the wind picks up.

The whole of Sunday the 16th and Monday the 17th are a write-off, with poor conditions and the swell staying weak and crumbly. There’s really nothing to get excited about.

We get a tiny spike on Tuesday morning the 18th, still only 3ft but from the SSW with a clean 16-second period. Energy is moderate at 605, but the wind is cross-shore from the WNW. It’s still not good. Then things get weird in the afternoon. A new, short-period WNW swell jumps up to 7ft, but it’s only a 7-second period, so it's going to be a choppy, messy closeout. The combined energy jumps to a strong 842, but that’s wind chop, not surfable waves. It’s the kind of day that would be more fun on a kite than a surfboard.

Wednesday the 19th and Thursday the 20th are back to small, weak, and unappealing. We’re in a real lull.

Friday the 21st sees the short-period WNW swell again, with 5ft in the afternoon but still that junky, weak 7-second period. Not good. Saturday the 22nd is more of the same, 7ft in the afternoon but with the same 7-second period, just dumping close to shore.

Then, we hit the real dead zone. From the 23rd through the 26th, the swell just flatlines. We're talking 1ft to 2ft, long-period SW swells that are just too weak and straight to do anything at this break. It’s a big, boring stretch with no standouts. You’re better off doing something else.

Now, there is one date to circle on the calendar, and it’s a long way off. On Friday the 28th, we finally see some proper energy. The swell is 6ft in the afternoon, and the combined energy is up there at 923, which is strong. But, and it’s a big but, it’s a short-period WNW groundswell at 7 seconds. The direction is okay, but that period is trouble. It’s going to be a powerful, walled-up, and messy. The wind will be cross-shore, so it’s not going to be clean. For an advanced surfer at a spot like Saint Annes, it could be on, but it’s a long way out and far from guaranteed. It's promising, but treat it with serious caution.

Right at the end of the window, on Saturday the 29th, there’s another pulse of energy with an 880 reading, but again, it’s still that same short-period, WNW windswell. Not a good look.

So, my honest take: there’s no true standout in this 16-day stretch. The best you can hope for are a few rideable waves early on Saturday the 15th, if you're desperate, and maybe something more powerful but messy on Friday the 28th. That's it. The forecast can change, sure, but right now, this is a "check the cams, stay local, and don't drive" kind of outlook.

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.
