The Lowdown

G’day, Rusty here with the imperial measure. Let’s be straight: looking at the next 16 days for Saint Annes, there’s not a whole lot to get excited about. This is a sheltered reef set-up, and the swell just doesn’t want to line up with the wind. The water sits at about 64° which is a touch warmer than usual for this time of year, but that’s about the only bright spot.

Right now, from Friday September 11, we’ve got a long-period groundswell pumping in from the SSW at 3 ft, but it’s 16 seconds apart, which is very long period. That kind of energy is better for a point or river mouth, and at a sheltered reef with a cross-shore wind of 12 mph, it’s just messy with a cross-chop. No good. That pattern sticks around for days. The combined energy is moderate (574) but it’s wasted.

Saturday September 12 brings a tiny 2 ft SW swell with a light cross-on breeze. The swell period drops to 14 seconds—still long—but it’s just too small and the wind isn’t clean. Later on Saturday, a short-period 6 ft WNW swell shows up with a period of only 7 seconds. That’s steep, crumbly, and combined with a cross-wind at 12 mph, it’s a choppy mess. The energy jumps to moderate (531), but the quality is poor.

By Sunday September 13, that same short-period swell pushes up to 10 ft from the WNW, but it’s only 8 seconds. That’s too big for beginners and with a fresh cross-wind of 22 mph creating lumpy cross-chop, this is only for the most die-hard experts. The combined energy is strong (1044), but it’s not surf-able for most.

Monday September 14 is the first time we see a glimmer. The height drops to 6 ft from the WNW with an 8-second period and a light cross-wind of 6 mph. It’s still short-period and the wind isn’t fully offshore, but the energy is moderate (844). It’s a marginal call—questionable tide conditions—but if you’re desperate, this is the best of a bad bunch. The crowd factor is “often” so expect company even for this.

Tuesday September 15 morning: an offshore wind from the WSW at just 3 mph hits that 5 ft WNW swell with a 9-second period. That’s the cleanest the wind gets in the whole 16 days, with a combined energy of 461. It’s still marginal, but an offshore breeze on a reef can make even average swell feel better. This is the standout moment. Get in then, because it’s short-lived.

From there, from Wednesday September 16 all the way through to Saturday September 26, it’s a rinse-and-repeat of small to medium swells from the SSW or WSW, with periods ranging from 14 to 19 seconds, all with cross-shore or cross-on winds. Heights hover around 2 ft to 5 ft. None of it hits the quality mark. There’s a slight spike on September 24 and 25 with 5 ft WNW swell and a 10-11 second period, but the wind stays cross-on. It’s still only marginal at best.

The overall energy stays moderate (most values in the 400-700 range), but it never fires. No standouts past that Tuesday September 15 morning. If the ocean doesn’t deliver, there’s always next forecast.

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.
