The Lowdown

Alright, Rusty here. Let's have a look at what Saint Annes has in store for us over the next couple of weeks.

To be straight with you, the outlook for Saint Annes is a tough one. This is a sheltered reef break that's pretty particular about its conditions, and for the vast majority of this 16-day window, the stars just aren't lining up. From the 12th of August right through to the 23rd, we're looking at a long stretch of poor to marginal conditions. The wind is mostly cross or cross-onshore, and while the swell is there, it's coming in from the SSW, which isn't its optimum direction from the WNW. The water temp is sitting at 64°, which is about a degree and a half warmer than average for this time of year, so it's a little on the mild side. The combined energy is moderate, with values like 306 to 640, but it just doesn't matter when the wind chops it up. The swell is small, sitting around 2ft to 4ft, so it's not like there's any size to get excited about either.

The pattern shifts a bit starting around the 21st of August, when the swell direction finally swings around to its preferred WNW. The height picks up to 5ft to 5ft, but the period drops to a short, weak 7 to 8 seconds. This is a windswell, not a proper groundswell. The wind is still cross-onshore, and the quality is still rated as poor. There's a hint of a long-period SW groundswell returning around the 24th and 25th, with periods of 17 to 18 seconds, but the swell is tiny at 2ft to 2ft, and the wind is back on it. The 26th and 27th see a slight bump in size to 3ft to 4ft from the SW, but with that same cross-onshore wind, it's just not going to be a good wave.

Honestly, there isn't a single standout session in this entire 16-day forecast for Saint Annes. The winds just won't cooperate, and the swell quality is either poor or the direction is wrong. If you're desperate, the least bad looking window might be the morning of the 27th of August, with a 4ft SW swell and a 15-second period, and the wind is a light cross-onshore. But even then, it's a marginal call. For a reef break that needs clean conditions, this is a stretch of time to maybe give the board a rest. The setup is more interesting for kite surfing than paddle surfing on most days here.

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.
