The Lowdown
Right, let’s have a look at what we’re working with for the next couple of weeks. First off, it’s pretty bleak out there. There’s nothing rideable for the first few days; we’ve got a string of poor surf conditions with minimal wave energy and messy winds. The water’s sitting at 63°, which is about average for this time of year – no real surprises there.
The first hint of anything that’s even close to a paddle comes on Thursday the 12th of September morning at Saint Annes. It’s a reef break, sheltered spot, and the swell is only 2ft from the SW, with a very long period of 14 seconds. The energy is moderate at best (471). The wind is light and cross-shore, so it’ll be small and inconsistent, but there might be a few clean little runners if you’re desperate. It’s rated as marginal, so keep expectations low.
Then things get a bit weird. Saturday afternoon, the 14th of September, shows a sudden jump – 7ft from the WNW, but with a short period of just 7 seconds. That’s windswell, and with a moderate cross-shore, it’s going to be a lumpy, choppy mess. There’s moderate energy (774), but the quality just isn’t there. Not worth it.
Honestly, the whole 16-day window is a grind. There’s no standout, no proper clean swell with good wind. A few of the later afternoons – like Sunday the 22nd and Monday the 23rd of September – show 3ft from the SW with a long period of 16-17 seconds, and the wind is light cross-on. The energy is moderate (around 600-700), but it’s still rated as marginal or poor. The cross-on wind will mess up the face at this reef.
If I had to pick one moment that might just about be worth a look, it’d be the morning of Sunday the 22nd of September. There’s a 3ft SW groundswell (18-second period) with light cross-shore wind and strong wave energy (742). It’s still only a marginal call, and the swell is small, but those long clean lines could produce a few glassy waves early. Crowds are often here, so you won’t be alone.
But truth be told, this is a tough run. For a reef like Saint Annes that needs a decent angled swell and clean conditions, we just don’t get it. It’s a blank run for this area, really.

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.
