The Lowdown
Alright folks, Rusty here. Let's be straight with you about the stretch ahead. Honestly, looking at this 16-day run, we are in for a tough patch. The surf quality is just not there. The first decent bit of swell doesn't show up for a while, so we’re looking at a long, flat gap with nothing to recommend.
The only break on the menu is Morro Rock. It’s a consistent spot, fairly exposed to the swell, and it likes a northwesterly direction. The water temp is sitting at 62°F right now, which is bang on average for this time of year, so no surprises there. But don’t let that fool you; the waves are a letdown.
The first real chance of seeing anything rideable comes on Thursday, August 20th. Through the morning, we’ve got a tiny 2ft swell from the WNW with a long period of 11 seconds. The wind is a light cross-onshore breeze from the SW at 3 mph. The combined energy is moderate at 237. But the catch is that it’s still being called poor surf. Thursday afternoon gets a bit of size at 4ft from the WNW, but the period drops to a short 6 seconds and the wind goes onshore. It’s just not happening.
Friday the 21st is more of the same, really. A 4ft NW swell in the morning with a short 6-second period, and it’s poor. The afternoon stays at 4ft from the WNW with a slightly better 9-second period, but the wind is onshore. Energy is moderate but the quality is missing.
Saturday the 22nd morning has a 4ft WNW swell, 8-second period, and onshore wind. Then the afternoon gets weird – a tiny 1ft swell but with a very long 21-second period. That’s a lot of energy packed into a small wave, with 298 on the energy scale. But it’s a long-period groundswell. At a spot like Morro Rock, that could just break too straight. And the onshore wind kills any chance of it being clean.
Sunday the 23rd and Monday the 24th show a persistent pattern of small, long-period swells (18 to 19 seconds) with cross-on/onshore winds. The energy numbers are decent (262 to 343), but the height is tiny and the wind is not our friend. It’ll be bumpy and uninviting.
To be honest, there isn’t a single standout session in this whole 16-day window. Every single entry in the forecast is marked as poor surf conditions. The winds are never truly offshore, it’s always at best a light cross-on breeze. The swell directions don’t line up perfectly for clean conditions. There's nothing to get excited about.
So, the call here is a flat-out miss for the area. We have a big gap from now until about Thursday the 20th with nothing on offer, and even after that, it’s all poor quality. This is just one of those blank runs where you’d be better off tuning the fins or checking the kite gear, because for a standard paddle surf, it’s a no-go. Stay patient, the forecasts can change, but right now, there’s nothing to chase.
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.
Morro Rock is 21 km (13 miles) from Atascadero. If you plan a vacation in San Luis Obispo, look for hotels and other accommodation in Atascadero. Atascadero has rooms for a wide range of budgets as well as car hire and transport links.
