The Lowdown
Alright, Rusty here, let's talk about what's on the menu for us at Saint Annes.
Right off the bat, I gotta be straight with you – the next few days are looking pretty flat and messy. We've got a bit of swell in the water from the 4th through the 6th, around 1 to 4 feet, but the wind is coming from the west and northwest, which is cross-onshore for this reef. The energy is weak to moderate (between 423 and 986), and the water is sitting at 61°, which is about normal for this time of year. It's not going to be any good. You'll be battling small ripples and chop.
Then we get a real dead stretch from the 7th of September right through the 12th. The swell drops to almost nothing, and the wind is all over the place. There's simply nothing to ride. It's a proper blank run.
Now, keep your eyes on Wednesday the 9th of September. That morning, the wind swings to the northeast, blowing straight offshore. That’s clean. The swell bumps up to 4 ft from the SSW, with a period of 11 seconds. The energy is solid (745). It’s a small, clean wave, but it’s the only window of actual good surf in the whole forecast. The wind is light, so it should be glassy. This is a reef break, but it's a bit sheltered, so it might be a little tricky with the tide, but it's our best shot.
After that, the wind turns ugly again. Thursday the 10th has a 5 ft swell from the SW with a bigger energy (1029), but it's cross-onshore with a southerly wind, so it'll be poor. The next real hope is a pulse of bigger swell around the 18th of September, with waves hitting 10 ft from the WNW, but that's almost two weeks out, so it's just a whisper on the horizon. The wind is still wrong for it, and at that size, it's only for the experts anyway.
So, honestly, there's only one standout. If you're going to paddle out, do it on the morning of Wednesday the 9th. It won't be epic, but it'll be clean. The rest of the time, you're better off changing your fins.
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.
