The Lowdown
Alright, Rusty here, talkin' about Morro Rock. This spot is consistent, open to the NW swell, and good for beginners. Water temp is pretty normal for this time of year.
The first week is a dud. From Wednesday the 16th right through Monday the 21st, it’s just poor conditions. Tiny swell, long period, wind on it or cross-on. Combined wave energy is low to moderate (214 to 668), but it doesn't matter—it's a mess. Not worth it.
Then it gets good. Tuesday the 22nd of September is the standout. Clean 3ft swell from the SW at 16 seconds—proper groundswell (energy at 513). But the key is the glassy wind. Light airs from the SSW. For Morro Rock, that means clean, peeling waves. Crowds can pop up, but a Tuesday morning should be manageable.
Wednesday the 23rd and Thursday the 24th mornings are almost as good. Same glassy start, SW swell around 3ft, period dropping from 15 to 14 seconds. Energy is still strong (600 and 427). Dawn patrol is the move.
Then we get another clean shot on the 30th of September, Wednesday morning. Glassy winds again with a 2ft SW swell at 16 seconds and 400 energy. Small and clean. And on the 1st of October, Thursday morning, we see a punchier 4ft WNW swell at 10 seconds, glassy, with 408 energy. That one could be a fun little wave.
The best on offer is the morning of Tuesday the 22nd. That glassy long-period SW swell is the pick of the bunch. The following two mornings are right there with it. The October 1st morning is a hopeful long-range shout. Anything else is blown out or too small. If the swell hits 5ft on the 26th, the wind is bad, so skip it.
Get up early for those glassy windows and you’ll score.
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.
