Alright folks, Rusty here. Let's talk about what's cooking at Cape Mendocino.

Honestly, looking at the next couple of weeks, it's a pretty grim run. We're looking at a long stretch of mostly poor conditions, with wind and swell alignment just not working in our favour for the most part. The water is sitting at a very cold 51°, which is a full 5° colder than normal for this time of year, so you'll want a thick steamer.

There's a big gap of several days with no real surf recommendations. The first window of anything worth paddling out for is Monday afternoon, July 6th, but even then it's a marginal call. We've got a 6ft swell from the NW, but with a short period of 8 seconds and a moderate cross-shore wind creating a chop, it’s not going to be pretty. The combined energy is moderate at 1159, but the wind will kill the shape.

The next slightly better moment comes on Monday morning, July 13th. Still a cross-shore wind, but the swell is a bit cleaner at 5ft from the NW with a 9-second period. It's a marginal wave at best, and the moderate breeze will keep things choppy.

The one standout, and I say that with caution, is Thursday afternoon, July 16th. A week and a half away, so far from guaranteed, but it’s the best we’ve got. The wind lightens up a touch to a cross 12 mph, and we see a mix of swells. The main one is a 8ft NW swell with a short, weak 8-second period, but there’s also a 3ft long-period groundswell from the WNW at 18 seconds. That longer-period energy will bring some shape, and the combined energy is a solid 1211. This spot is fairly consistent but for an advanced-only crew; at 8ft it’s getting into expert territory. A point break or reef would be ideal for that long-period wave, but at Cape Mendocino's exposed beach setup, those long-period sets could close out a bit. Still, it's the cleanest looking window on the cards.

For the rest of the run, from Tuesday the 7th through to Monday the 20th, it’s a parade of 12-22 mph cross-shore winds, small lumpy swell, and scores that don’t excite. Several late July days see a drop to tiny 2ft to 2ft leftover swell and even stronger winds. There’s just no spark.

Bottom line: save your energy. If you're desperate, keep an eye on the 16th of July for a possible session. Otherwise, this forecast is a blank stretch—it’s one of those runs for the area. Forecasts can always flip, but right now, there's nothing to rush for.

Rusty.

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.
