The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Saint Annes over the next couple of weeks.
Honestly, this is a tough stretch. We’ve got a pretty long run of poor surf conditions coming up, with nothing worth paddling out for until we get to the very end of the forecast window. The first few days are all showing "poor surf conditions" and the wind is either cross or cross-onshore, which is just messing up any chance of a clean wave. The swell is a mix of weak short-period stuff and some bumpy windswell, but it’s all pretty scrappy.
The water temp is sitting at 62°F which is basically normal for this time of year, so no surprises there.
The first real glimmer of hope comes on Saturday, 6th September. That afternoon, the wind drops right out and goes glassy. We’ve got a 4ft SSW swell coming in at a long 16 seconds, and the combined energy is a solid 1190 (strong wave energy). That’s a groundswell, and it’ll be lined up nicely for the reef. The glassy conditions are a massive positive – you’ll be looking at clean, smooth faces. This is the standout session of the whole forecast. The swell direction is SSW, which is pretty close to the optimum WNW direction for this spot, so it should wrap in well.
The morning of that same day (Saturday, 6th September) is also worth a mention. It’s got a 3ft SSW swell, still a decent 16-second period, but the wind is light cross-onshore, so it won’t be as pristine as the afternoon.
The week before that is a write-off. There’s a few days where the height gets up over 7ft, but the wind is always cross or cross-onshore, and the period is a short 6-8 seconds, so it’s just lumpy, bumpy windswell. Not worth the effort. The 8ft swell on Wednesday, 2nd September afternoon is just big, raw, and messy – only for the die-hards with a death wish, and even then, it’s not good.
So, to wrap it up: we’ve got a long, dry spell of nothing until the very end. The one and only true standout is the afternoon of Saturday, 6th September. That’s your window. Glassy, long-period groundswell, and decent size. Get on it.
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.
