The Lowdown
Alright, let’s get into the outlook for Morro Rock. It’s going to be a test of patience, with a couple of bursts of real energy later on.
Right from the start, the first week is a total doldrums. From the beginning of September through about the 8th, it’s consistently poor. Swell is tiny, often under 3 feet, with steady onshore wind from the WNW blowing it out. The water temp at the start is 60°F, which feels a bit colder than usual for early September – a solid 3°F below the norm.
Around the 9th, we get a little flicker. Wednesday morning the 9th brings a 2-foot SSW swell with a very long 19-second period, putting combined energy up to 363 (moderate). It’s a marginal call with a light cross-onshore breeze. The break is fairly exposed to the NW, so that long-period SSW swell won’t be hitting it head-on. The afternoon drops right back off.
The real window, the one that’s worth waiting for, kicks in on the 14th of September. Monday afternoon the 14th sees the swell jump to 8 feet from the WNW, with a period of 8 seconds. That’s proper – the combined energy is 827 (strong). That size is for experts only, mate. The wind is light onshore from the West, so it’ll have a bit of a bump, but with that much water moving, it’ll be a heavy ride. Over 8 feet is well into the “experts only” zone.
Tuesday morning the 15th holds strong with a 6-foot NW swell at 984 energy (strong). Light cross-onshore wind out of the WNW will keep the surface a little textured. Wednesday the 16th morning keeps it solid at 5 feet from the WNW, 10-second period, and 672 energy (strong). The wind is light and cross-onshore again. For a reef point like Morro Rock, that longer period makes the waves stand up and wrap in nicely, but the sets will be spaced out a bit more.
The pick of the whole run? Monday afternoon the 14th through Tuesday morning the 15th. That’s your best shot at size and power. The wind isn’t perfect, but it’s the only time the swell really fires. Thursday the 17th also has a small but clean morning with a 4-foot NW swell and light offshore wind, followed by a tiny 2-foot swell in the afternoon but with a crazy 21-second period – that’ll be super clean and glassy, just with long waits between sets.
Crowds at Morro Rock can sometimes be a thing, but with this mostly quiet forecast, you won’t have to fight for a peak.

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.
