The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cookin’ at Morro Rock.
Honestly, I gotta be straight with you—this 16-day window is a real struggle. The guidance tells me Morro Rock is a consistent spot that’s fairly exposed to the northwest, and it’s a beginner-friendly wave. But the data we’re looking at? It’s a tough read. The water temp is sitting at 61°, which is about average for this time of year, so nothing wild there.
The whole outlook is a mess of “poor surf conditions” with no real standouts. The combined swell energy is weak to moderate at best, with the highest reading being 328 (moderate energy) on Monday afternoon, August 10th, but even then the description says “marginal surf forecast or questionable tide conditions.” That’s the closest we get to a pulse, but it’s not enough to get stoked about.
The swell is mostly small, with heights hovering between 2 ft and 4 ft for the first week, coming from the WNW or SW, with periods all over the place—from short 5-second wind slop to longer 14-second groundswell. The wind is constantly onshore or cross-onshore, which is a killer for this spot. There’s a bit of a long-period pulse mid-week around August 13th with a 12-second period from the WNW, but again, the wind is messy and the report says poor surf.
Even the second week doesn’t save us. From August 17th onward, the swell gets a little bigger, hitting 6 ft on Monday afternoon the 17th, but that’s a short-period 6-second wind swell, which is just lumpy and weak. The energy is only 204 (moderate), and the wind is onshore. It’s a no-go.
Bottom line: Morro Rock is a consistent wave, but this forecast is a total flatline. There’s a big gap of days with no real surf on offer, and when there is a tiny bump, it’s ruined by the wind. I wouldn’t bother paddling out for this—it’s more of a beach walk and coffee situation. If you’re desperate, maybe the Monday afternoon, August 10th, with that 3 ft WNW swell and moderate energy (328) is the least bad option, but it’s still a “marginal” call. Trust me, you’re not missing much.
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.
