The Lowdown

Alright, Rusty here. Let's have a look at what's cookin' for Cape Mendocino over the next couple of weeks.

To be straight with you, things are looking pretty grim. We've got a solid 16-day window ahead, but the first 14 days are basically a write-off. The surf is small, the wind is ugly, and the conditions are just plain poor. It's a tough stretch.

The only faint glimmer of hope comes right at the very end of the forecast. On Monday, August 10th, there's a slight uptick, but it's still marginal. The best chance for a wave is later in the afternoon, with a 1.6ft swell from the SW.

Now, the one standout, and I mean *the only one*, is on Tuesday, August 11th. Cape Mendocino is our spot, and it's an advanced wave. It's "fairly consistent," but it's exposed to the SW swell. The morning session sees a small 2ft swell from the SSW, but the wind is a light, cross-onshore breeze from the SW. That's okay, but it's the afternoon that gets my heart beating a little faster. The swell direction shifts to SW, and the wind goes from a light breeze to a true offshore, blowing from the W at only 3 mph. That's glassy, clean, perfect conditions. The water temp is about 56°F, which is normal for this time of year. The downside is that the swell is tiny, but with that offshore wind, it'll be as good as it's gonna get. It's a very long period groundswell at 19 seconds, so it's got real energy. Don't expect a crazy amount of waves, but the ones that come through will be clean and lined up. It's a spot for the experienced crew, and with crowds being "sometimes," you might have it to yourself.

The rest of the week after that is just more small, messy cross-shore junk. The combined swell energy for that Tuesday afternoon is a moderate 568 (moderate wave energy). It's a long-range call, so it's promising but not a guarantee. For now, sit tight, and maybe get your gear ready for that Tuesday afternoon session.

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.
