The Lowdown
Alright folks, Rusty here. Gotta be straight with you, this stretch ain't looking like a classic. We've got a super long gap before there's anything really worth paddling out for, so we're talking about a bit of a waiting game.
The first sign of any surf at Saint Annes pops up on Friday morning, July 17th, with a tiny 2ft groundswell from the WNW. The period is a huge 18 seconds, which means long, clean lines, but the energy is weak (585). The wind is a light offshore, which is a massive plus, but the swell is just too small and the model is calling it marginal. The water temperature is 59°, about 1° cooler than normal, so it's a touch nippy for the time of year. Friday afternoon goes flat with poor conditions.
We then have a real dry spell. Saturday the 18th and Sunday the 19th see a small bump of 3ft from the SW, but with cross-onshore winds messing things up. Monday the 20th is the same story. Nothing doing.
The Best Bet on Offer
The standout is Tuesday morning, July 21st. We get a solid 5ft swell from the SSW, with a period of 14 seconds. The combined energy jumps to a healthy 1235 (moderate). The wind is a light cross-onshore. It's not perfect, but it's the best we've seen by a long shot. At 5ft, it's a good size for a reef break, but it's getting a bit big for beginners. The real bummer is that the wind isn't offshore, and a spot like Saint Annes, which is a sheltered reef, really needs that clean wind to shine. Crowds are often a problem here, so expect company.
Tuesday afternoon drops to 5ft with the same vibe, and then Wednesday the 22nd fades back down to 3ft. The rest of the week is a messy mix of small SW swell and cross-onshore winds, not offering much for a paddle surfer.
Looking further ahead, the second week is a bit of a mixed bag of moderate energy. Saturday morning July 25th has a 3ft SSW swell with a very long 21-second period, but again, cross-onshore wind. By Tuesday July 28th afternoon, we get a solid 5ft SSW swell (period 18 seconds) with a strong energy reading of 2019, but the wind is still cross-onshore. It's a frustrating pattern.
The setup looks more interesting for a kite surfer than a paddle surfer on most of these days, with the consistent cross-onshore winds and moderate swell. Honestly, for a clean paddle, you're best off setting an alarm for the morning of the 21st and hoping the wind plays ball. It's a waiting game.

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.
