The Lowdown
Alright, Rusty here. Let’s look at what’s on the menu for the next couple of weeks.
Honestly, the next week is a bit of a bummer. We’ve got a long stretch of poor surf with mostly onshore or cross-onshore winds and wave energy that’s weak to moderate. The water’s at 60°F, which is a little cooler than average for this time of year around Morro Rock. Nothing really worth suiting up for until we get into the second week.
The first real chance shows up on Friday the 11th. The morning session looks clean with a light cross-onshore breeze, but the main event is the swell. We’ve got a solid 6ft swell from the SW with a 12-second period, and the combined energy is a strong 1043. That’s some proper power, but for most folks that’s expert territory – over 5ft starts to push beginners out, and at over 6ft, you’d better be confident. The onshore wind picks up in the afternoon, messing it up a bit.
Saturday the 12th and Sunday the 13th are still messy with onshore wind and choppy conditions.
Now, keep your eyes on Friday the 18th. It’s a long way off, so treat it as a hopeful rumor, not a sure thing. The morning looks clean with a light onshore breeze and a 2ft swell from the SW, but the big story is the period – a very long 20 seconds. That’s proper groundswell, and at Morro Rock it’ll wrap in nicely, though long-period swells at a beach break can be a bit straight. The combined energy is moderate at 593 in the morning, building to a strong 918 by the afternoon with a 3ft, 19-second swell. With light winds all day, the afternoon could be the best of the whole forecast. Clean, with that deep, powerful energy rolling through.
So, don’t stress about this week. Do something else. The action, if it happens, is on the 11th for the brave, and possibly the 18th for cleaner, longer rides.
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.
