The Lowdown

Alright, grab your board. Let’s talk about Saint Annes.

Right off the bat, it's a pretty grim outlook, mate. Over the next few days, we’ve got small, cross-choppy waves and not much to get excited about. The water temp is sitting at 61° – that’s about normal for this time of year, so no surprises there. The swell energy is moderate, around the 650 to 700 range on Friday, but the conditions are just poor with that cross-shore wind kicking up a mess.

Saturday isn’t much better. We see a slight bump in swell to 4ft to 4ft from the SSW, with period dropping from 17 down to 16 seconds. That longer period suggests some energy, but it’s still cross-shore and the wave comment says “marginal” at best. The combined energy climbs to 1097 on Saturday afternoon, which is solid moderate energy, but the wind just ruins it.

Sunday and Monday are more of the same – waist-high slop, cross-onshore winds, and zero score. This stretch from Friday through to about the middle of next week is basically a write-off. There’s a gap of several days here with nothing worth paddling out for.

Things get a little more interesting on Friday, September 4th. The afternoon shows a shift – swell height hits 5ft from the WNW with a 12-second period, and the combined energy jumps to 1326. That’s moderate-to-strong energy. The wind is light cross-shore, so the surface could clean up a bit. It’s still only a “marginal” call, but it’s the best we’ve seen in a week. If you’re desperate, that’s your window.

Saturday the 5th holds some small waist-high leftovers, but by Saturday afternoon the wind picks back up and it turns ugly again. The following week is a desert of poor or marginal conditions, small swell, and cross-onshore breezes. Nothing stands out as a classic session.

The only flicker of something different is on Saturday, September 12th afternoon. Swell jumps to 8ft from the WNW, but with a period of just 7 seconds – short-period wind swell. That’s going to be lumpy, crumbly, and only for the experienced crew. The combined energy is 922, solid moderate. Still only a “marginal” rating though, so don’t get your hopes up.

In short, Saint Annes is a tough call this fortnight. There’s no standout day. If you’re really keen, aim for Friday, September 4th afternoon for the best chance at a few clean-ish ones. Otherwise, it’s a waiting game.

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.
