The Lowdown
Alright folks, Rusty here. Let’s have a look at what Morro Rock’s got cooking for us over the next couple of weeks. It’s a bit of a mixed bag, so don’t go getting your hopes up too high too early.
Right off the bat, we’re looking at a real slow start. Friday the 11th is a write-off with tiny, choppy surf and onshore winds kicking things around. The early part of the window is pretty grim, with nothing worth paddling out for through the weekend and into the start of the following week. You’ll be waiting until around the 21st of September before we see a glimmer of something rideable.
Now, that late period around Monday the 21st and Tuesday the 22nd is where we find the only real standout. It’s not gonna be massive, but we’ve got clean conditions with light, even glassy, winds from the west and southwest. The swell is small, around 3 ft, coming from the southwest, which is a decent direction for this spot. The energy is moderate (around 490-791) but it’s a long-period groundswell coming in at 16-17 seconds. That longer period means better shaped waves, but at a beach break like Morro Rock, it can make things a little straight. Still, with glassy conditions, this is your best bet in the whole outlook. The water temp is about average for the time of year, nothing crazy to report there.
Don’t get too excited about the end of the window around the 25th and 26th – it’s still marginal and the cross-onshore breeze starts to creep back in. Overall, it’s a quiet one. If you’ve got a kite, the bigger, windier days on the 13th (8 ft) and 19th (8 ft) might catch your eye, but for a paddle surfer, hold out for those cleaner mornings around the 21st and 22nd. That’s the pick of the bunch.
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.
