The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the menu for the Morro Rock area over the next couple of weeks. I gotta be straight with you – it’s a pretty grim picture for the most part. We’re looking at a long, dry stretch with hardly anything worth paddling out for.
We kick off on Friday the 14th with a tiny, weak 2ft swell from the WNW, but the wind is already cross-on and it’s just a mess. The combined energy is a measly 55, so there’s nothing to get excited about. That same story holds through the weekend and into the start of the new week. The swell stays small, the period is short, and the wind is never in our favour. It’s all just poor surf conditions.
The first real glimmer of anything happens on Saturday the 22nd of August. We finally see a push of swell, hitting 7ft from the WNW early in the morning. The combined energy jumps to 740, which is moderate, and the wind is light and onshore, keeping it clean. The period is just 8 seconds though, so it’s a short-period wind swell, not a groundswell. It’s still a marginal situation, but if you’re desperate, that’s your best shot. The water temp is about average for this time of year, so no surprises there.
The rest of the run is more of the same. There’s a spike on the 24th with 7ft swell again, but it’s messy and scored as poor. Then on the 25th, we get a weird spike of 2ft swell from the SW with a very long 16-second period – that’s a groundswell – but the energy is high (415) and the wave comment is marginal. That long period at a fairly exposed spot like this could be interesting, but it’s tiny.
Honestly, for a consistent break like Morro Rock, this is a tough run. The forecast is shaky, and the conditions are just not lining up. If you’re a kite surfer, the bigger, choppier days on the 17th and 18th might look more appealing, but for a paddle surfer, it’s a whole lot of waiting.
Stay patient, keep an eye on the charts, but for now, it’s a no-go.

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.
