The Lowdown
Alright folks, Rusty here. Let’s get into it. Gotta be straight with you – the outlook for Saint Annes over the next couple of weeks is a tough one. We’re looking at a long stretch of small, weak, and mostly messy surf. The water is sitting at 60°, which is a bit colder than normal for this time of year – you’ll want a good hood.
The first bit of surf that’s even worth a mention starts up on Friday afternoon, August 7th, but it’s marginal at best. We’re looking at a tiny 2ft swell from the SSW, but the period is a solid 19 seconds, which is a long-period groundswell. That kind of energy at a sheltered reef break like Saint Annes can sometimes produce a cleaner wave, but the cross-onshore wind is messing it up. The combined wave energy is moderate (435), but it’s just not coming together for a proper paddle.
The rest of the first week and into the second is more of the same story. We’ve got a lot of days with cross-on winds and small, weak swell. The Sunday morning of August 9th sees the swell bump up to 3ft from the SSW, still with that long period, but the wind is still a nagging cross-onshore. The energy is moderate (478), but the conditions are holding it back. It’s frustrating because the potential is there, but the timing is off.
Heading into the second week, things get a bit more interesting, but not necessarily better for surfing. Around August 15th and 16th, the swell starts to build a bit, with 4ft from the SSW and energy climbing into the strong range (679-723). The problem is the wind stays tricky, and the wave quality is still being described as poor. By Monday, August 17th, the wind is whipping up from the NW at 12 mph, and we’ve got a 7ft short-period, wind-driven swell (7 seconds) that’s just a bumpy, choppy mess. That setup is more interesting for kite surfing than paddle surfing, honestly.
The real punch comes on Tuesday, August 18th afternoon. We’re looking at an 8ft swell from the WNW, but the period is a snappy 7 seconds and the wind is howling at 16 mph. The wave energy is very strong (1212), but this is expert-only, heavy, wind-affected stuff. The same goes for Wednesday, August 19th, with 8ft swell and moderate to strong energy. It’s big, it’s powerful, but it’s not clean.
Honestly, there’s no true standout session in this 16-day window. The swell is either too small or too messy, or when it gets big, the wind ruins it. Look for a sneaky early morning on the 10th of August, where the wind is light and offshore, but the swell is only 4ft. If you’re desperate, that’s your best bet. Otherwise, keep your gear waxed and wait for the next system.
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.
