The Lowdown
Hey folks, Rusty here. Let's talk about what's shaping up for Morro Rock over the next couple of weeks. Gotta be straight with you, it's a pretty bleak picture for the most part. We're looking at a long stretch of onshore or cross-onshore winds and crummy conditions. The swell energy is all over the place, but the quality just isn't there. There's a glimmer of something much better right at the tail end of the period.
For the first week and a half, starting this Thursday the 10th, it's a tough watch. Thursday morning is tiny at 1 ft from the NW with a weak 68 combined energy, and a cross-onshore breeze messing it up. Thursday afternoon does see a jump to 3 ft from the SW with a solid 16-second period and moderate energy (653), but the wind is directly onshore, so it's a write-off. Friday is more of the same, small and onshore. Saturday the 12th has a bit more size, especially Saturday afternoon with 7 ft from the WNW, but the period is a short 7 seconds and the wind is howling onshore – that's messy, choppy, and honestly, more suited to a kite than a paddle board at a beach setup.
The following week continues the trend. Sunday the 13th has some size, up to 8 ft in the afternoon from the WNW, but it's cross-onshore and choppy. Monday the 14th morning actually has a more manageable 6 ft from the NW with a light cross-onshore breeze, and the energy is strong at 824, but the conditions are only called "marginal". It's the best of a bad bunch that week, but still far from epic. The rest of that week into the weekend of the 19th and 20th is a frustrating mix of onshore winds and small, weak swell with combined energy readings mostly between 29 and 573. We get some long-period SW groundswell, but it's small (2 ft to 3 ft) and the cross-onshore winds ruin any chance of a clean wave.
Now, here's where it gets interesting. Mark your calendars for Monday the 21st of September. That morning, the stars nearly align. We've got a clean 3 ft SW groundswell with a long 17-second period and a very strong combined energy of 502. The wind is forecast to be glassy – a gentle NNW breeze of 5 km/h (3 mph). That's a major positive. For a spot like Morro Rock, which is fairly exposed to NW swell but sees this SW groundswell, and it's a consistent beginner-friendly break, glassy conditions with that long-period energy could actually produce some super clean, albeit small, lines. That’s the standout, no question. It's a true rarity in this forecast period, so if you're flexible, that Monday morning is the only time I'd genuinely get excited about. The afternoon looks a bit more marginal with a light onshore breeze picking up.
After that, Tuesday the 22nd is back to small and cross-onshore, and the rest of the outlook into the end of the month fades back into poor conditions with onshore winds and short-period junk. So, a long, dry spell with one golden window. Keep your eye on that Monday morning swell.
Rusty.

Information about the Morro Rock Surf forecast
The above surf forecast table for Morro Rock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Morro Rock can be found by selecting the local surf guide option on the grey menu. Our Morro Rock 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 (Morro Rock) 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 Morro Rock 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.
Morro Rock is 21 km (13 miles) from Atascadero. If you plan a vacation in San Luis Obispo, look for hotels and other accommodation in Atascadero. Atascadero has rooms for a wide range of budgets as well as car hire and transport links.
