The Lowdown
Alright, let’s break it down for Saint Annes. This is a rough few weeks, I’m not gonna lie.
The first week and a half is mostly flat and messy. The swell is small, the wind is nearly always cross or cross-onshore, and the surf quality is poor. The combined wave energy is weak, usually under 1000, so there’s just not much power.
The first real chance of anything decent is Saturday morning, July 25th. The swell is around 3ft from the southwest, with a long period of 21 seconds – that’s groundswell, which is good for a reef. The wind is a gentle breeze out of the WNW, so it’s side-shore, which means a bit of bump. The combined energy jumps to 1112, so there’s some push, but it’s still only marginal.
The next few days are similar. Sunday and Monday see swell around 3ft to 4ft, still with that long-period SW groundswell. The wind stays side-shore or side-onshore, but never clean. On Monday morning, July 27th, we get a light side-onshore breeze, which is the closest to glassy conditions we get, but the swell is just okay.
The best session of the whole 16 days is Tuesday afternoon, July 28th. The swell is 4ft from the SSW with a 17-second period – that’s proper groundswell. The combined energy hits 1769, which is strong, and the wind is a gentle side-shore breeze out of the WNW. That’s your best bet. The waves will have some shape and power, but it’s not a classic day.
After that, it’s all downhill. By Thursday, July 30th, the swell drops and the wind turns more side-onshore. The energy falls to 361 and 730, and the surf goes flat and choppy. The whole first week of August is poor, with tiny swell, short periods, and persistent side-onshore winds. The only thing that changes is the wind direction, but it doesn’t help.
If you’re keen, Tuesday afternoon July 28th is your window. Otherwise, you’re waiting for a long time.

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.
