The Lowdown
G’day, I’m Rusty, and I’ve run the numbers for your local coast. The next 16 days look pretty lean. Water temps at Saint Annes are 62°, right about average for the season, but the wave quality isn't with it.
Starting on Sunday, August 9th, there’s a small 3 ft swell from the SSW at 15 seconds. That’s a deep-water groundswell with moderate energy (415), but the cross-onshore wind from the west at 6 mph keeps things bumpy. It’s a marginal call.
Monday the 10th is a flat day. Morning has a 2 ft swell with onshore wind, afternoon only a 3 ft WNW swell at a short 10 seconds. Poor all round.
Tuesday the 11th through Thursday the 13th are all poor. Swell stays weak, from 1 ft to 2 ft, with cross-onshore winds. Not a single window.
Friday the 14th sees a 2 ft SSW swell with 14 to 18 second periods, but the cross-onshore wind from the west kills it. Marginal morning, poor afternoon. Saturday the 15th offers a 3 ft to 4 ft SSW swell with 16-second periods and energy from 642 to 818, but again—cross-onshore wind. So close, yet so messy.
From Sunday the 16th right through to Monday the 24th of August, it’s a long stretch of poor to marginal conditions. Swell heights run from 1 ft to 3 ft, but winds are cross-onshore or cross-shore, with some moderate breezes cranking up to 15 mph. A few mornings, like the 20th and 21st, show a marginal call, but the wind direction or short period (9 seconds on the 21st) ruins any hope of clean lines.
Saint Annes is a sheltered reef that likes a WNW swell, and the wind never really works in its favour here. Every session is either bumpy with cross-onshore ripples or just plain choppy.
There are no standout days in this 16-day window. It’s a quiet stretch, but don’t lose hope completely—forecasts can flip.

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.
