The Lowdown
Alright folks, Rusty here. We’ve got the full 16-day window for Morro Rock to look at, and I gotta be straight with you – it’s a tough stretch. We're looking at a long, dry spell before anything even gets close to worth paddling out for.
The pattern starts off weak and stays that way for over a week. From Sunday the 9th all the way through to Saturday the 16th, it’s a real struggle. The swell is tiny, mostly under 3.3 ft, and the wind is locked in from the WSW or SW, blowing cross-on or onshore. The wave energy is almost non-existent, sitting under 100 (68) for most of the first few days. It’s all just small, wind-affected slop. The water temp is about average for this time of year, so no surprises there, but it doesn't make the surf any better.
There’s a bit of a pulse showing up on Monday the 17th. That morning we’ve got a 3.3 ft swell from the SW with a very long period of 14 seconds. The energy jumps up to a moderate 427, which is the most we’ve seen by a long shot. The wind is light and onshore from the W, so the surface might not be perfect, but that long-period groundswell will have some push. Still, this is a beach break set-up, and long-period SW groundswell can often run straight and close out on a beach. It’s a marginal call at best.
For the rest of the second week, we get a few little bumps in size, but the wind is mostly onshore or cross-on, and the quality just isn't there. A couple of mornings on Saturday the 22nd and Sunday the 23rd show some energy back into the 300-range, but the wind kills it.
Honestly, the only real standout, if you can call it that, is the Monday the 17th morning session. With the very long period swell and the moderate energy (427), it’s the best on offer, but it’s not clean. If you are a beginner, this 3.3 ft swell is fine height-wise, but the long period and onshore wind make it a challenge. For intermediate to advanced surfers, it might be worth a look, but don’t expect perfection. For the rest of the window? A blank run is more normal for this area when the swell and wind don't line up.
Stay patient, keep an eye on the charts.

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.
