The Lowdown
Alright folks, Rusty here. Let’s have a look at what Saint Annes has in store for us over the next couple of weeks. I gotta be straight with you – it’s a tough stretch. The pattern is one of mostly poor to marginal conditions, with very few windows worth paddling out for. There’s a fair gap of nothing special to start, and the only real interest comes later on.
First up, the water temp at Saint Annes is sitting at 65°, which is a touch warmer than normal for this time of year. Not a big deal, just a little bonus.
We kick things off with a dud. Saturday the 12th brings a tiny 2ft SW swell with moderate energy (345), but the wind is a cross-shore breeze and the report just says poor surf. Not worth it.
Sunday the 13th gets a bit messy. Morning has a 4ft WNW swell but with a short period of 7 seconds and moderate cross-winds. Then Sunday afternoon sees the swell jump to 10ft from the WNW, with a period of 8 seconds and strong energy (1044). But the wind cranks up to 22 mph cross-shore, making it lumpy and dangerous. That’s expert-only territory, and even then, the conditions are horrible.
Monday the 14th morning is the first flicker of hope. A 6ft WNW swell, moderate energy (844), period of 8 seconds, with a light cross-shore breeze. It’s only rated as marginal, but it’s the best we’ve seen. The afternoon goes back to poor. Tuesday the 15th morning has a 5ft WNW swell with light offshore wind (SW at 6 mph) – now that’s clean. But it’s marginal, so don’t expect perfection.
From the afternoon of the 15th right through to the morning of the 19th, it’s a real flat spell with tiny swell and mostly cross or onshore winds. A few sessions show long-period SW groundswell (15-19 seconds), but the height is barely 2ft to 2ft. Combined energy is moderate (284-500), but there’s just not enough size to get excited about. Keep your board in the car, but don’t rush.
Now, here’s the standout. On Saturday the 19th afternoon, we get a pulse: 6ft from the WNW, period 8 seconds, with solid energy (772). The wind is a moderate cross-shore from the NW. It’s still marked as poor, but it’s the first real size in a week.
But the *real* highlight comes Sunday the 20th morning. This is the best on offer by a long shot. A 7ft NW swell, period 8 seconds, with strong energy (1216). The wind is a gentle cross-shore from the NW. That’s clean, powerful, and punchy. For an advanced surfer, this is the session to target. It’s a bit much for beginners though – over 5ft, so keep that in mind.
After that, the second week (from the 21st to the 27th) settles into a long stretch of small SW groundswell, mostly 2ft to 3ft, with periods around 14-16 seconds. The winds are light and mostly cross or cross-on, keeping things rideable but unremarkable. Combined energy sits in the moderate range (260-741). No real standouts here. The morning of Saturday the 26th offers a little 2ft SW swell with a light cross-offshore breeze from the NNE, which will make for clean, smooth waves – but it’s tiny.
Saint Annes is a sheltered reef setup, and it likes a WNW direction as its optimum. The best we get is that Sunday the 20th morning pulse, which is close to that direction and has the most energy. The rest is a waiting game. Conditions are inconsistent, and the break is fairly consistent, so it’s not abnormal to have these blank runs. Don’t lose hope – forecasts can change.
Rusty, signing off.

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.
