The Lowdown
Alright folks, it’s Rusty here. Let’s be straight: the next sixteen days are a tough stretch for Morro Rock. We’ve got a massive gap of poor conditions right from the start, and it’s not until late in the second week that anything even hints at life. I’m looking at a lot of flat, weak, or just ugly surf.
For the first week, from the end of August right through to the 4th of September, it’s a write-off. Thursday the 28th kicks off with a 6ft swell from the NW, but the wind is a cross-on 12 mph, and combined energy is only moderate at 459. It’s choppy and poor. The following days offer similar stories: 5ft on the 29th, 4ft on the 30th – all with onshore or cross-onshore winds. The water temp is 61°, which is about average for this time of year. Don’t even bother.
There’s a tiny flicker of hope on Monday the 31st morning – a 5ft NW swell with a slightly longer 8-second period and a light 6 mph onshore breeze. The combined energy is moderate at 379. But the score is marginal at best. It’s a maybe, but barely. After that, we drop into flatness for days: the 1st, 2nd, and 3rd of September are all below 3ft with energy readings as low as 47. It’s dead.
We finally see something on Friday the 4th of September afternoon. A 5ft swell from the NW with a 12-second period – that’s a longer-period groundswell, so it’ll have more push and better shape, but it can be tricky at a place like Morro Rock. The combined energy jumps to a strong 598, so there’s some power behind it. Winds are onshore at 9 mph, but it’s clear. This is the standout of the whole period, but it’s still rated as poor. For a moment, it’ll be the biggest and best shaped wave we’ve seen, but don’t expect perfection.
Beyond that, the 5th and 6th are back to messy, weak surf. Then from the 7th to the 11th, it’s a lot of small, unappealing slop with energy under 180. One more point of interest: Saturday the 12th of September afternoon shows a 8ft WNW swell with a short 7-second period and a combined energy of 537. That size (over 8ft) is expert-only territory, and with short period, it’ll be a steep, dumpy wall. Honestly, unless you’re a charger, that’s more of a kite-surfing setup than a paddling one.
So, to sum it up: the first week is a blank. The second week is mostly blank too, with Friday the 4th offering the only real pulse of swell energy. Long-range stuff is always less certain, but that’s the best we’ve got. It’s a grim run, but forecasts can change – we might get lucky with a better wind shift.
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.
