The Lowdown
Alright, this is Rusty, and I’m lookin’ at the next couple of weeks for Morro Rock.
Right now we are in a bit of a flat spell. Most of the first week and a half is just not doing it for us—blown-out, messy, or just too small to get excited about. The only real glimmer shows up around Monday the 14th of September, but it’s barely a whisper.
Now, the standout window in the whole 16-day run? You want to circle Tuesday the 15th of September and Wednesday the 23rd of September. The best of the bunch is gonna be Tuesday the 15th of September in the morning at Morro Rock. The water temp is sittin’ around 63°F, which is just about normal for this time of year—nothing weird there. You’ve got a 4ft swell coming from the WNW, with a period around 8 seconds. Winds are light from the SSW at 3 mph, keeping it a light cross-onshore with just small wind ripples. It’s not glassy, but it’s darn close. The combined swell energy is sitting at 376—that’s moderate energy, enough to get a wave under your feet. The break itself is consistent and fairly exposed to swell from the NW direction, and since the swell is coming from the WNW, it’s a decent match. It’s a beginner-friendly spot, but with crowds possible here, you might have some company.
The other date worth a look is Wednesday the 23rd of September in the morning. Same break, Morro Rock, with a 3ft swell out of the SW at a 15-second period. That’s a longer period groundswell, so the waves will have some shape and power, making it great for a point or reef layout like this. Winds are light from the WNW at 3 mph, so it’s a light cross-onshore again, with a combined swell energy of 415—still moderate. It won’t be huge, but it’ll be clean and fun.
Most of the other days? The surf is poor, with onshore winds or choppy conditions. The afternoons in particular get messy, with moderate breezes and lumpy seas. Saturday the 12th and Sunday the 13th of September see some bigger swell, 8ft and 8ft, but with cross-onshore winds and periods of just 7-8 seconds, it’s just a washing machine. Too big for beginners, and with the short period, it’s just a closeout mess. That setup honestly looks better for kite surfing than paddle surfing.
After that second week, the swell drops off again. Thursday the 24th of September has a 3ft swell from the WNW at 10 seconds, but it’s onshore and poor.
So, the long and short of it: if you’ve got a window, aim for the morning of Tuesday the 15th of September or the Wednesday the 23rd of September. The rest, you might as well clean your wetsuit and wait. That’s all I’ve got.
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.
