The Lowdown

Alright folks, Rusty here. Let's be straight about it – we’ve got a tough run ahead at Morro Rock. The next two weeks are looking pretty bleak for any proper waves. We’re staring down a stretch of almost entirely poor surf conditions, with a real gap of nothing good from now until the very end of the forecast window.

The pattern for the next week and a half is a grind: mostly small, weak swell with onshore or cross-onshore winds. The combined swell energy stays weak, bouncing around (35) to moderate (479) most days, but it’s almost always coupled with that wind blowing right onto it, making a mess of things. For a beginner spot that’s consistent, that’s a real letdown. Expect a lot of bumpy, choppy water with no real shape.

We finally see a flicker of hope on the morning of Monday, August 31st. The wind goes glassy, a light southerly breeze. Swell swings around to the WSW at a solid 15-second period, offering some long-period groundswell energy (286). The height is only 2ft, so it’s tiny, but that glassy surface and long-period pulse could make for some clean little peelers on a push tide. It’s the only session in the whole outlook that’s described as expecting good surf. The crowds are sometimes an issue here, and with conditions this rare, you can bet a few others will have the same idea.

After that brief window, the onshore flow returns. By the morning of Tuesday, September 1st, the swell bumps up to 5ft from the NW (505), but with a light cross-on breeze and marginal conditions, it’ll be a lumpy, blown-out mess, likely too messy to be fun.

So, the only real standout in this entire 16-day stretch is that glassy Monday the 31st. It’s not going to be big, but for clean, tiny waves, that’s your window. Everything else is a skip.

Stay patient,
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.
