The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for Saint Annes. I gotta be straight with you – this isn't looking like the kind of run that gets the stoke levels high. We're looking at a pretty bleak 16-day window, with a massive gap of nothing worthwhile at the start.
The first sniff of anything that even *mentions* a surfable wave is on the morning of Sunday, the 9th of August, but even then, it's a mess. The water temp is sitting at 62°F, which is basically bang on average for this time of year, so no surprises there.
But here's the deal: the whole period is plagued by poor surf conditions. The swell is small, mostly under 3ft, and the direction is all over the shop – mainly from the SSW, which is a long way off the optimum WNW for this sheltered reef break. The combined energy readings are all over the place, with some moderate numbers like 313 (weak) and 459 (moderate), but none of it translates to a proper wave. The wind is consistently on or cross-on, never truly offshore, which means the surface is going to be bumpy and messy.
Even the afternoons, which sometimes offer a glimmer of hope, are just "marginal" at best. The swell is there, but the quality is not. The period is long, over 15 seconds, suggesting a groundswell, but at a beach or reef break like this, that long period with a poor wind angle just makes things fat and closey.
The only time the swell actually gets above 3ft is around the 15th of August, hitting 4ft, and the energy climbs to 793 (moderate), but it's still a SSW swell with cross-on wind. The same story repeats itself right through to the 23rd of August. There's a brief spike of 7ft on the 18th of August, but it's a short-period windswell (7 seconds) and the wind is cross, so it's just a messy, choppy wall of water. Not one for the paddle. If you're into kite surfing, that afternoon might have some grunt, but for a surfboard, it's a no-go.
Honestly, there's no standout session here. Not a single one. It's a long stretch of poor to marginal conditions. The forecast is reliable for the near term, and it's just not good news. Sometimes it's like this – the area goes quiet, and we just have to wait for the next system to line up. Don't hold your breath.
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.
