The Lowdown
Right, folks, Rusty here. Let’s have a look at what’s on the cards for Saint Annes.
First up, the water temp is sitting at 59°, which is a bit colder than normal for this time of year – nothing too wild, but you’ll want a decent wetsuit.
The outlook is a bit of a grind, to be honest. There’s a lot of poor surf conditions and marginal forecasts filling the diary. The swell is small, mostly around 3 ft to 3 ft, and it’s coming at us from a cross-on or cross direction. The wind is light and gentle, but it’s not helping much. The combined wave energy is moderate, ranging from 374 to 779.
Saturday the 18th is a write-off. Sunday the 19th morning is marginal at best.
The first real chance to even think about it comes Sunday the 26th of July. The combined swell energy jumps to 828 (moderate), with a 3 ft swell from a long period of 19 seconds. That’s a groundswell, and this reef setup should handle it better than a beach break. The wind is still cross-on, so it’s messy, but it’s a step up.
Then Monday the 27th of July into Tuesday the 28th of July offers the best of the bunch. Monday morning sees a 4 ft SSW swell with an 18-second period, and the combined energy is 1319 (strong to very strong). The wind is a light cross-on, so it’s still a bit chopped, but the energy is there. Tuesday the 28th of July has a 4 ft SSW swell, again with strong energy (1299-1644). The wind picks up to a moderate breeze, which will chop it up, but for a reef that likes a WNW optimum, this is a rare window of decent size.
Wednesday the 29th of July is a caution. A 8 ft WNW swell hits, but with a short period of 8 seconds and a cross-on wind. That’s a lot of close-out, slopey energy. It’s going to be a big, mushy mess. Only for the hardcore with a big board.
Beyond that, it tails off into small, weak surf with poor conditions through to the 2nd of August.
The standout here is the Monday the 27th of July. The 4 ft at 18 seconds from the SSW gives the reef a bit of life, and the light cross-on wind is the cleanest we’ll see. It’s not perfect, but it’s the best on offer. If you’re keen, that’s your window.
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.

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.
