Table - best surf conditions forecast for Cape Mendocino over the next 16 days.
Alright, Rusty here. Let’s talk about the next couple of weeks at Cape Mendocino.
I gotta lay it down straight: the whole 16-day outlook is pretty flat. There’s a long stretch of poor surf starting now, with a lot of cross-shore winds that are just messing up the surface. The water is a cold 51°F – that’s a solid 5°F colder than it should be this time of year, so you’ll want a thick suit.
The first time you might even consider paddling out is Saturday, July 18th. It’s only “marginal” with a small 3ft swell from the WNW, 16-second period. That’s a long-period groundswell, which can be a bit wonky at a beach break, but the energy is moderate (829). The wind is still a moderate cross-shore, so it’ll be lumpy.
Sunday, July 19th, is a bit better. By the afternoon, the wind drops to a light cross-shore breeze (3 mph) with a 3ft swell from the SW at a very long 17 seconds. The energy is solid (751). That lighter wind makes it the cleanest we’ll see, but with the swell being small and crowds being “sometimes” a thing, it’s a roll of the dice.
Then we hit another dry spell with poor conditions until Wednesday, July 22nd. That morning, a bigger pulse of 8ft NW swell rolls in, but it’s short-period at 9 seconds and the energy is strong (1211). At 8ft, it’s too big for beginners and only for experts. The wind is still a moderate cross-shore, so it’s gonna be a messy, powerful shorebreak.
The rest of the forecast, from July 25th onward, is just more of the same: small, inconsistent swells with cross-shore winds. Nothing lines up for a clean, top-quality session.
There’s no real standout here. The best bet is that Sunday afternoon, July 19th, with the light wind and the long-period groundswell – it’s the only window where the surface cleans up. The big swell on Wednesday, July 22nd, is for the hardcore crew who don’t mind a fight.
Keep your chin up, the forecasts can always change.

Information about the Cape Mendocino Surf forecast
The above surf forecast table for Cape Mendocino provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cape Mendocino can be found by selecting the local surf guide option on the grey menu. Our Cape Mendocino 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 (Cape Mendocino) 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 Cape Mendocino 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.
Cape Mendocino is 47 km (29 miles) from Eureka. If you plan a vacation in Humboldt County, look for hotels and other accommodation in Eureka. Eureka has rooms for a wide range of budgets as well as car hire and transport links.
