The Lowdown

Right, grab a coffee, have a listen to Rusty. The outlook for the next couple of weeks is a bit of a mixed bag, to be honest. We've got a solid run of small, choppy windswell for the first week, and then it looks like it tries to build but the wind just doesn't play ball. The whole period is plagued by onshore or cross-onshore winds, so the wave quality is a real struggle. Let's walk through it.

The only spot in the frame is Morro Rock. It's consistent, and it's a fairly exposed beginner-friendly spot, which is good for the crew just finding their feet. At this time of year, the water temperature is about average for the year, so nothing unusual there.

We kick off with a few days of nothing much. Tuesday the 18th and Wednesday the 19th are a write-off. We're looking at a weak, short-period windswell from the WNW, only about 4 ft to 5 ft, combined wave energy is pitiful (100-183), and the wind is cross-on or onshore, making it messy and choppy. Not worth a paddle.

Thursday the 20th shows a flicker of something. The swell pushes up to 6 ft from the NW on the morning (energy of 543), but the wind is straight onshore. It's a total mess. The combined energy is moderate, but the quality is just not there. For the rest of that week and into the next, it's the same story: small, weak swell with onshore wind. The wind is mostly a light to gentle breeze, but it's never offshore, so the surface is always bumpy.

There is a bit of a pulse around the 26th and 27th of August. The swell height climbs to 8 ft and even 8 ft from the WNW, with a period of 8 seconds. The combined energy jumps up to a strong 874 and 862, which is a lot of water moving. But the wind is still cross-on or onshore, and at 8 ft, that's getting into expert-only territory, especially with a short period that will be fat and challenging. The wind state is described as "moderate cross-onshore and choppy," so it's not a clean wave. The sheer size and energy make it look more interesting for the kite foilers than for a paddle surfer.

The very end of the forecast, around the 1st and 2nd of September, sees the energy drop back down to weak levels again. The whole 16-day window is a tough one for Morro Rock. The surf is always there, but the quality is never there. The wind just never lines up properly. If you're desperate for a paddle, the mornings of the 26th or 27th might offer the biggest lumps, but be prepared for a bumpy, choppy ride. It's a classic case of the swell and the wind fighting each other.

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.
