The Lowdown
Alright, let’s talk about this spot. Saint Annes is the only game in town, and it’s a tough one to get excited about over the next sixteen days. We’ve got a long, slow slide from a short burst of average swell into a whole lot of nothing. Wind is the enemy here—cross-shore or cross-onshore almost every day, just knocking the surface around.
Start with Sunday the 13th. A 4ft WNW swell rolls in, but it’s only 7 seconds apart—weak and shifty. Wind is cross-shore at 12 mph, so expect bumpy, rippled conditions. Combined energy is a low 307. Not good. That afternoon, the swell jumps to 8ft but still short period at 8 seconds, and the wind cranks to 22 mph. That’s messy and lumpy—too big for beginners, and the quality is cooked.
Monday the 14th morning is your best early bet: 6ft WNW swell with 8 seconds, light cross-shore breeze at 6 mph. It’s still choppy, but the score slips to "marginal." This is the high point. By afternoon it’s back to poor. Tuesday the 15th morning actually has offshore wind from the SW at 6 mph, a rarity here, with a 5ft WNW swell at 9 seconds. Energy hits 461 (moderate). Still marginal.
From Tuesday afternoon on, it’s a slow bleed. Swell drops under 3ft and stays there. The period gets long—16, 17, even 19 seconds. That’s groundswell, but coming from the SW or SSW, which doesn’t suit this reef. The energy numbers stay in the 300 to 500 range (weak to low moderate). Wind stays cross-shore or cross-onshore. The one clean moment comes on Sunday the 27th afternoon: glassy, no wind, only 2ft at 12 seconds. If you’re floating a log, it might be glassy and rideable.
So the best on offer? Monday morning the 14th and Tuesday morning the 15th. After that, it’s a long wait for tiny, clean but tiny conditions. Water temp is about 64°F, which is spot on for time of year. Crowds are "often" here, but with this outlook they’ll be sparse.
Bring a patient attitude and a log. This is a ten-day stretch with basically nothing. Rusty, out.
Short Range ForecastMostly dry. Warm (max 23°C on Sun morning, min 14°C on Tue night). Winds decreasing (fresh winds from the NW on Sun afternoon, calm by Mon night). | Days 4-6 Weather SummaryMostly dry. Very mild (max 19°C on Wed afternoon, min 14°C on Wed morning). Wind will be generally light. | ||||||||||||||||||||

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.
