Alright folks, Rusty here, let's get straight into it. Right now, things are looking pretty flat and messy for the cape. We've got a long stretch ahead with very little to get excited about, so strap in.
We're starting off on Friday, 3rd July, with small, weak swell from the SSW at just 2 ft, but the wind is howling out of the north at 15 mph, making for a lumpy cross-shore chop. The energy is weak (285), and the whole setup is just poor. This pattern sticks around through the weekend. Saturday, 4th July, sees a brief bump to 7 ft from the NW, but that's short-period wind swell at 8 seconds, blasted by a 18 mph NNW breeze. The water is sitting about average for the time of year. This is more of a kite-surfing show than a paddle-surfing one with that strong cross-wind and lumpy chop. The energy jumps up to (688), but the quality is just not there.
We finally get a whiff of something a little more interesting on Monday, 6th July. Cape Mendocino looks at a 7 ft swell from the NW in the morning. The period is still short at 9 seconds, and the wind is cross-onshore at 9 mph, creating a choppy surface. The energy is strong (1118), and it's labeled as marginal. However, for an advanced spot, there might be some raw power to work with, but it's going to be a battle with the wind. It's also a bit much for beginners. The afternoon sees a similar 7 ft swell, but the wind picks up, making it even rougher.
After that brief pulse, we slip back into a long, flat spell. From Tuesday, 7th July, right through to the 18th of July, it's just day after day of small, weak, and badly wind-affected swell. The energy figures are mostly in the moderate range (300-600), with periods either too short or too long for this exposed beach setup, and the wind never lays down. There are no standouts, no clean windows, nothing worth paddling out for. The forecast is consistent in its mediocrity, unfortunately.
So, bottom line: The only semi-interesting moment is Monday, 6th July, for advanced surfers who don't mind a chop. But for the rest of this 16-day stretch, you're better off waiting for the next system to roll through. It's a tough run for the cape.
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.
