The Lowdown

Alright folks, Rusty here with the lowdown, and I’m not gonna sugarcoat it – the next couple of weeks are lean. Real lean. If you’re thinking of paddling out, you might be better off checking the wind forecast for kiting instead.

We’re looking at a long stretch of nothing good at the start. The wind is stuck out of the west-northwest, blowing cross or cross-onshore, and the swell is mostly short-period junk. Water temps are pretty average for this time of year – nothing strange going on, just no energy.

The only spot we got to talk about is Saint Annes (reef). It’s a sheltered little reef break that really needs a strong west-northwest swell to light up. Problem is, every single session in the 16-day window is marked as “poor surf conditions.” Not one good wave.

We do see a few pulses of size later on. By Thursday afternoon, August 27th, the swell hits 2.5m from the west-northwest, but with a short period of just 8 seconds and a moderate cross-shore wind. There’s a lot of power (combined energy of 1063), but it’s gonna be choppy and messy. That trend continues into the end of the month: 2.4m, 2.5m swells with the same wind direction, and by Saturday afternoon the 29th, winds gust to 30 km/h, making it a lumpy, cross-shore mess. Those are expert-level waves size-wise, but the quality is shot.

For a reef like Saint Annes, the wind and short-period combo makes this look more like a kite surfer’s playground than a paddle surfer’s dream. There’s push, but no polish.

The closest we get to something rideable is the morning of Wednesday, August 19th and Thursday morning, August 20th. We get a small 0.8m to 0.9m swell from the south-southwest with a nice long period (14 to 16 seconds) and a light cross-onshore breeze. It’s tiny and the wind keeps it from being clean, but it’s the only period where the wave comment doesn't say “poor.” Still, it’s a 1 out of 10 – barely worth the drive.

Bottom line: blank run. If you absolutely have to get wet, try the early mornings of the 19th or 20th, but keep expectations real low. Forecasts can flip, but right now, it’s a waiting game.

Stay patient,
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.
