The Lowdown
Alright, let’s put it in more familiar numbers.
Mate, Rusty here. It’s looking bleak for Saint Annes for the next 16 days. From Friday the 21st through the end of next week, it’s mostly poor surf. The water temp is around 62°F, which is normal for this time of year, no surprise there.
Day by day, it’s a grind. Friday the 21st through Tuesday the 27th – every session is “poor.” Swell is weak and short-period, and the wind is cross or cross-onshore, making a mess. Thursday the 27th afternoon sees a 7ft WNW swell with combined energy at 597 (moderate), but the wind is a moderate cross-shore – lumpy. Same story on Wednesday the 26th: a 6ft swell in the arvo, energy at 499, but choppy.
The best chance comes on Saturday the 29th morning. We’ve got a 7ft WNW swell, period of 8 seconds, and combined energy at 1488 (strong!). The wind is a light cross-shore, the cleanest we’ll see. The swell direction is ideal for Saint Annes, and at that size, it’s expert territory. Crowds are likely, so get in early. Even so, the overall quality is only rated 2/5 – it’s the best of a bad run.
The afternoon of the 29th drops off with a 3ft SSW swell and cross-wind.
The second week, from the 30th of August into September, is all poor. Sunday the 30th afternoon has an 8ft WNW swell with 1233 energy (strong), but it’s cross-shore with a moderate breeze – messy and only for the keen experts. The 31st, 1st, 2nd, 3rd – all poor. The 4th of September has a small offshore wind in the morning, but the swell is tiny.
So, if you’re not an expert, you’re looking at a two-week drought. The only real chance for a clean wave is the morning of Saturday the 29th. Don’t get your hopes up for anything else.
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. 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.
