The Lowdown

Well, grab a coffee, because I’m looking at a pretty lean stretch ahead for Saint Annes. This is a sheltered reef break that needs a very specific swell direction to really fire, and the next couple of weeks just aren’t delivering that. The water is sitting at 62°F, which is bang on average for this time of year, so no surprises there.

The biggest problem is the wind. It’s blowing from the WNW almost constantly, which is cross or cross-on at this spot. That means the surface is going to be choppy or have a cross-chop for the vast majority of the period. You’ll see a few pulses of swell, but the wind just ruins the potential.

Let’s be honest, from Thursday the 20th right through to the end of August, it’s a tough watch. The waves are small, the wind is messy, and the quality is poor. The only real flicker of hope comes late in the first week of September. On Thursday, the 3rd of September, the afternoon has a 10ft WNW swell rolling in, with a combined energy of 1340, which is strong. The wind is a gentle cross-shore, which is actually the best we’ll see. That’s a big swell for a sheltered reef, so it’s strictly for the advanced crew. The period is a short 8 seconds, so it’ll be a bit bumpy and disorganised, but the size and the clean-ish conditions will make it the standout window by a long shot.

The Friday the 4th of September afternoon also has a solid 8ft WNW swell with 1175 energy, but the wind is cross-on, so it’ll be a bit messier. Still, if you’re an expert looking for something to get stuck into, that’s your second option.

Basically, the first two weeks are a write-off. The surf just isn’t there. The last few days of the period offer some size, but it’s not clean. The one day to circle is Thursday the 3rd of September afternoon. It’s not perfect, but it’s the only thing that’s going to get the heart pumping around here.

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.
