The Lowdown
Alright, folks, Rusty here. Let’s break down what we’ve got at Morro Rock. I’m not gonna sugarcoat it – the first week and a half is mostly a bust. The wind is onshore or cross-onshore for days, ruining any chance of clean surf. The water temp is 62°F, which is about normal for this time of year, so no surprises there.
The first real sign of life doesn’t come until Tuesday, September 15th. The morning shows a 5ft swell from the WNW, period of 8 seconds, but it’s cross-onshore. The combined energy is moderate (378). The afternoon picks up to 7ft from the WNW, still onshore, with stronger energy (602). That’s a “maybe” session if you’re brave.
The real standout, if you can call it that, is from Thursday, September 17th through the end of the forecast. The winds finally drop to a light onshore breeze, and we get some longer period groundswell. Thursday morning has a 4ft WNW swell, period of 9 seconds, and light onshore wind (10 km/h). The energy is solid (310). The afternoon is similar.
Friday, September 18th and Saturday, September 19th are your best bets. Friday has a 4ft WNW swell, period of 10 seconds, light onshore wind, and the energy is strong (508). The swell direction (WNW) is perfect for Morro Rock, and the period is long enough to give the waves some punch. Saturday sees a shift to a SW swell, 2ft to 2ft, but the period jumps to 18 seconds – that’s proper groundswell. The energy is still strong (377 to 429) and the winds are light cross-onshore. This is your pick. A long period SW groundswell with light winds, even if the size is small, will offer clean, lined-up waves. It’s a point break setup, so the long period won’t be an issue. Crowds are sometimes a thing here, so expect some company.
So, to put it simply: forget the first week. The best on offer is Friday, September 18th (4ft, WNW, 10 sec, light wind, good energy) and Saturday, September 19th (2-2ft, SW, 18 sec, light wind, great energy). That’s your window. It’s a long way out, so keep an eye on the forecasts, but it’s the only time the stars align.
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.
