The Lowdown
Alright, let's be real with each other. The next 16 days aren't going to have you waxing up for a dawn patrol of glory, that's for sure. It's looking pretty ordinary, with a whole lot of onshore wind and short-period slop. The energy is mostly in the moderate range, and a lot of it is just going to be messy. There is a long-period groundswell early on, but it’s tiny and might just close out this here beach break. Keep your expectations low, and you won't be disappointed.
The water's about normal for this time of year, so no surprises there.
Starting with Morro Rock (Morro-Rock), Thursday the 20th is a total flat, bumpy mess. We're talking 0.7m of onshore junk with a bit of energy, but it's not worth the drive. Friday and Saturday are more of the same. We get this weird, long-period southwest pulse from Sunday the 23rd through Wednesday the 26th, but the period is so long it’s not breaking right at the beach. It’s just a tiny, weak dribble. That’s nearly a week of nothing good.
Then, on Thursday the 27th, things start to wake up a bit. The swell bumps to about 1.3m to 1.7m, but the period drops back to 7-8 seconds. It's windswell, but at least it has some push to it. Friday the 28th is similar.
The weekend of the 29th and 30th is the high point. Saturday afternoon and Sunday afternoon both see 2.0m swells from the WNW. There’s strong energy behind it, around 430-441, so there's some real grunt. But here’s the catch: the onshore wind is going to be there all day, making it lumpy. Saturday afternoon is the pick of the weekend, but 2.0m is starting to push it for beginners. For anyone with a bit of experience, it's game on.
Next week, the consistency falls apart. By Monday the 31st, it's 2.0m and getting bigger, but the wind builds. Tuesday the 1st of September is a full-blown onshore howl with 2.2m waves, and Wednesday the 2nd sees the biggest swell of the entire forecast at 2.5m, but it's also the windiest. That's expert territory, and it'll be a battle just to get out. The last day, Friday the 4th, is the most interesting long-shot. It's a small 1.2m swell, but the wind is a light offshore breeze, which could actually clean it up and make it the fun, rideable day of the run.
So, your best bet is Saturday the 30th afternoon. That's the one to circle on the calendar. The rest is just a waiting game.

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.
