The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Saint Annes.
To be straight with you, the outlook across the whole sixteen days is pretty bleak. This reef break has a tough run ahead of it. The water temp is sitting at 60°, which is a bit colder than normal for this time of year – about 2° cooler – so don’t expect any tropical warmth here.
Right from the start on Thursday the 3rd, we’ve got a 0.7m (2ft) SSW groundswell with a long 18-second period, but the cross-shore wind is messing it up. The combined wave energy is moderate at 796, but the conditions are just poor. That’s a kick-off you don’t want.
Moving into Friday the 4th and Saturday the 5th, the swell nudges up to about 1.1m to 1.2m (4ft to 4ft) from the SSW, with periods still solid at 16 to 17 seconds, but it’s constantly cross-on or cross-shore wind. There's nothing clean. Energy drops from 986 down to 715, but it hardly matters when the surface is a mess.
Sunday the 6th is more of the same – the swell drops back below a meter, and the wind picks up again. The energy drops to 390 by morning. Not worth paddling out.
Then from Monday the 7th right through to Wednesday the 16th, we see a real grim stretch. For almost ten days, there’s no real surf to call. The swell direction shifts from SSW to a weak, short-period WNW (down to 6 to 9 seconds) and stays tiny or blown out. There are a few glimpses of size – like Thursday the 10th afternoon with a 2.1m (7ft) SSW swell, but with 40 km/h (25 mph) cross-on wind, it’s just a washing machine (energy 1261). Later, around Sunday the 13th and Monday the 14th, we get some 2.1m to 2.5m (7ft to 8ft) WNW swell, but it’s short period, onshore wind, and the forecast rates it as poor. That’s not fun surf; that’s a beating.
There is one slight glimmer at the very end of the run. On Wednesday the 16th afternoon, the wind goes glassy, and you’ve got a 0.5m (2ft) SW groundswell with a long 16-second period. The energy is low at 262, but glassy conditions are the only time this reef might give you a clean little wave. It’s surfable, but very ordinary – a last resort, not a stand-out.
Looking right across, the only real stand-out moment is that glassy session on the afternoon of the 16th. For a reef that needs clean conditions, that’s your window, but don’t expect much. The rest of the time, the combination of cross-onshore winds and poor surf quality means this is a quiet period for Saint Annes. It tends not to stay this grim forever, but this time, it really does.
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.
Saint Annes is 4 km (2 miles) from Port San Luis. If you plan a vacation in San Luis Obispo, look for hotels and other accommodation in Port San Luis. Port San Luis has rooms for a wide range of budgets as well as car hire and transport links.
