The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s shaping up for Saint Annes. This is a sheltered reef break, and it’s a pretty advanced wave, so keep that in mind. The water temp is sitting at 63°, which is about normal for this time of year – nothing to get excited about on that front.
Honestly, the outlook is a bit of a flat spell for the most part. We’ve got a long stretch of days with very minimal, poor surf. From Tuesday the 8th right through to the middle of the month, the energy is either weak or the wind is just messing things up. The first few days are seeing tiny, long-period swells, with the combined energy starting at 124 and climbing a bit, but the waves are just too small and the conditions are too crossed up to get excited about. It’s a real bummer.
The first real chance of something rideable pops up around Tuesday the 15th of September. The morning shows a bit of a pulse with 7ft swell from the WNW, but the wind is cross-onshore. The combined energy jumps to 1066, so there’s some grunt in the water, but the quality is still only marginal. It’s not the clean, groomed stuff we want.
The standout for the whole period, if you can call it that, is looking like the morning of Friday the 18th of September. We’ve got a 7ft swell from the WNW again, but the wind is a light cross-shore, and the combined energy is 634. The period is a very short 6 seconds though, so it’s going to be a bit of a bumpy, weak wave close together. It’s the best on offer, but it’s a far cry from perfection. For the rest of the second week, it’s a mix of tiny, cross-shore junk. There’s a few sessions with 3ft and 16-second period swells, but the wind is often just enough to chop it up. It’s a waiting game, and honestly, this setup might be more interesting for the kite crew than anyone trying to paddle into a clean reef slab.
Signing off for now.
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.
