The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s in store for our stretch of coast.
Right off the bat, I gotta be straight with you – the next two weeks are looking pretty grim for a proper paddle session. The first good surfable recommendation doesn't pop up until the 7th of September, and even that's a pretty ordinary affair. So we’ve got a solid week from the 31st of August right through to the 6th of September where the conditions are just plain poor. The wind is a constant problem, mostly cross or cross-onshore, and the wave state is described as choppy or with a cross-chop. The swell energy is weak to moderate, with values mostly in the low to mid-hundreds (247 to 882), but the quality just isn't there. It’s a real quiet patch.
The first faint glimmer of hope comes on Monday the 7th of September. Early morning, we’ve got a light rain and a light cross-offshore breeze from the NNW. The wind state is actually described as "clean" – finally! The swell height is only 2ft, coming from the SSW with a period of 14 seconds. The combined energy is a weak 303. It’s surfable, but very ordinary. That’s the only window that morning, and the afternoon session goes back to poor.
The next standout, and honestly the best on offer for the whole 16-day outlook, is on Monday the 14th of September. That afternoon, things get a bit exciting. The swell picks up to 8ft from the WNW, with a period of 10 seconds. The combined energy jumps to 1117, which is a moderate to strong energy. The wind is light from the WNW, cross-shore, with small crossing wind ripples. It’s still a "marginal" call due to tides, but that’s a solid wall of water. However, with the swell over 8ft, this is strictly for experts only. The Tuesday morning after that, the 15th, still has a 6ft swell from the WNW with a period of 10 seconds and energy of 801. It’s a bit smaller, but still a heavy wave for the experienced crew.
The winds are from the west and northwest through the whole period, and the water temp is about average for the time of year, so no surprises there. Just keep an eye on that 14th for the one true pulse of energy in an otherwise quiet spell.
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.
