The Lowdown
Alright, this is Rusty coming to you from the Morro Rock area. It’s a bit of a mixed bag looking out over the next couple of weeks, and honestly, the opening stretch is not what we want to see.
We’re looking at a bit of a flat spell to kick things off. The water temperature’s sitting around 60°, which is about what we’d expect for this time of year, nothing out of the ordinary there. The biggest problem is most of this period has poor surf conditions, with winds making a mess of things.
Right from Saturday the 29th through to the start of September, it’s a write-off. We’ve got a solid 5 ft swell from the WNW, but the wind is cross-on and onshore, turning the ocean into a choppy mess. Wave energy is moderate at best, hitting 191 on Saturday morning before building to a stronger 407 by the afternoon (combined energy of all swells directed here). Sunday’s similar—5 ft with cross-on wind. Saturday morning’s water temp is 60° with a -0.8° anomaly, so just slightly cooler than average.
Monday the 31st isn’t much better, with onshore wind and a weak 4 ft swell. This poor run rolls right through until Tuesday the 2nd of September, where we finally see a tiny glimmer. Wednesday morning looks a bit better, but the swell is coming from the SW at just 2 ft with a very long period of 16 seconds. That’s a lot of energy for such a small wave, and it might get a bit straight at a break like Morro Rock, which is a bit exposed to the NW. The energy is solid though, at 279. Still, the forecast calls it “marginal.”
The pattern stays frustrating through the first week of September. We get some glassy conditions on Monday the 7th with a 3 ft WNW swell, but it’s just not enough to get excited about. Thursday the 10th is interesting—the morning is glassy with a 2 ft NW swell and an 11-second period, but the real story is the afternoon. We’ve got a 3 ft SW swell with a very long 17-second period and combined energy of 751 (combined energy of all swells directed here). That’s a lot of power, but the wind is cross-onshore, so it’s a bit of a tease. Still, the direction matches what this spot wants (NW optimum), so it's worth a look if you're desperate.
The best bet in this whole forecast window is probably the tail end. Saturday the 13th of September finally gives us some size with a 6 ft NW swell on the morning and a 7 ft WNW swell later in the day. The wind is light or cross-onshore, but the break is exposed and the energy is strong, hitting 504 in the afternoon. At 7 ft, this is expert territory for Morro Rock. For the average surfer, the 6 ft morning session with light cross-onshore wind is the standout. The swell direction is on the money, but remember, this is a long-range call so treat it as promising but not locked in.
If you're a beginner, this entire forecast is rough. There’s nothing under 5 ft with clean conditions until potentially the 13th, and that’s too big. Kite surfers might have a better time on those windy afternoons.
Rusty out.

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.
