The Lowdown
Alright, let me tell you what I see, this is Rusty, and I've got the book on Morro Rock for the next couple of weeks. It's gonna be a bit of a mixed bag, honestly. The start is not looking good at all, with a lot of wind and junk surf, but there could be a few windows worth paddling out for if you're patient.
Right off the bat, this weekend is a write-off. Sunday the 13th is going to be a tough watch. The wind is howling from the NW around 19 mph in the afternoon, making it a lumpy, choppy mess on a chest to head-high plus 8 ft swell. The energy is solid albeit messy (808), but the conditions just aren't surfable. Monday the 14th is not much better with the cross-onshore wind and a 6 ft swell that’s still bumpy. It kinda feels like we’re stuck in a pattern of messy, wind-affected waves until mid-week.
We finally get a bit of a break around Tuesday the 15th. The wind eases right off to a slight air, just 3 mph from the SW, and we get a shoulder-high 5 ft WNW groundswell with a 9-second period. The combined energy (468) is moderate, and it won't be epic, but that light wind means it'll be the cleanest surf of the first week. It's marginal, but your best window before things go flat.
After a small pulse on Thursday the 17th, the middle of the window dries up. From the 18th through the 22nd, we're staring at knee to waist-high leftovers, mostly from the SW. The periods get long (17–19 seconds), which usually means better shape but long lulls. The energy in the water is still there (300–900) but the wave heights are just ankle-biters. A lot of that time, the wind is light and variable, which is a tease because the swell just isn't strong enough for a proper ride.
Now, digging into the deep end, things start looking more interesting for the final few days. Promising, but you know how long-range forecasts go. Around Friday the 26th, we start seeing a more consistent chest-high 4 ft swell from the WNW. The wind looks workable with a light cross-shore breeze, and the energy dips to a moderate 352. It's not huge, but it's a consistent signal.
For the true standout, I'm keeping an eye on Sunday the 27th. That morning, we're looking at a solid 5 ft swell from the NW with light cross-shore winds. It's pushing into the "getting big for beginners" territory, but the conditions look clean, and the energy (433) is decent for a point. That might be the best clean wave we see in the whole window, right at the end. The afternoon builds to nearly 7 ft, but it goes onshore, so the morning is your window.
In short, it’s a lousy start, a couple of short clean windows mid-week, and a promising but uncertain final weekend. I'd be a little excited about that Sunday morning the 27th if it holds. Be patient this first week, and maybe grab a kite if you've got one for the blustery days.
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.
