The Lowdown
Hey there, Rusty here again. Let’s talk about what’s cookin’ at Morro Rock for the next couple of weeks.
I gotta be honest, it’s a tough stretch ahead. We’re staring down a long, flat spell with nothing worth paddling out for until the very end of the forecast. From the start up until Thursday, August 27th, it’s mostly a bust.
Starting from Wednesday the 12th, the surf is tiny. We’re talking waves around 2 to 3 feet at best, with weak energy and cross-onshore breezes messing it up. There’s a little bump in size around the 19th and 20th, with waves hitting around 5 to 7 feet, but the wind is howling cross-onshore at 15 to 16 mph, making it choppy and ugly. That 7-foot stuff on the 19th afternoon is only for the experts, and it ain’t pretty.
Then from the 23rd onward, we get some long-period southwesterly groundswell – 16 to 19-second intervals – which sounds great, but the swell height is tiny, only 1 to 2 feet, and the wind is onshore. It’s a light breeze at first, but still onshore, so the waves will be weak and bumpy. The energy numbers jump up into the hundreds and even over a thousand, but that’s all period, not size.
The water temp is pretty normal for this time of year, nothing wild.
The only faint glimmer of hope is the morning of Thursday the 27th of August. We’ve got a small 2-foot swell from the SW with a long 14-second period and light onshore wind. The energy is strong (361), but the forecast calls it “marginal.” It’s the only thing in 16 days that even gets a mention.
So, what’s the call? Don’t bother waxing up for the next two weeks. This is a proper flat spell. For a spot that’s usually consistent, it’s a bummer, but it happens. If you absolutely need to get wet, keep an eye on that Thursday the 27th morning, but don’t expect much. This is more of a wait-and-see situation, or maybe a kite-surfing day if the wind lines up.
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.
