The Lowdown
Alright folks, Rusty here. Gonna be straight with you – it's a tough stretch ahead for Saint Annes. This is a sheltered reef break that works best on a WNW swell, and we just aren't seeing that. For the next week and a half, it's a whole lot of nothing special.
The surf is tiny, and the wind is nearly always coming from the wrong direction, putting a cross-on or cross-shore chop on everything. The water temp is about average for this time of year, nothing to write home about. The combined swell energy is weak, mostly sitting between 200 and 500 (204), which is just not enough to get the reef working. You'll be bobbing around on messy, 1ft to 3ft waves with a period around 15-19 seconds – that's a long, drawn-out groundswell that doesn't have the power to wrap in properly here. Basically, it's a lot of waiting for a weak, wonky ride.
From Tuesday 11 August right through to Thursday 20 August, the story is the same: poor surf conditions. There's a slight uptick on the morning of Saturday 15 August, where the swell hits 3ft and the score is a "1", but it's still cross-on and messy. The morning of Sunday 16 August is the same story. The only real change comes on the afternoon of Saturday 22 August. The swell jumps to 8ft from the WNW with a short period of 7 seconds, and the combined energy jumps up to 702 (moderate). That's big for Saint Annes, but it's a short-period windswell, meaning it will be a bumpy, choppy mess. The wind is still cross-on from the W at 6 mph. At 8ft, this is expert-only territory, but the conditions won't be clean enough even for them. Given the messy, windy conditions, this setup looks more interesting for kite surfing than paddle surfing.
Honestly, this is a blank run. There are no standouts in this entire 16-day window. The consistent onshore flow and tiny swell just aren't giving us anything to work with.
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.
