Right, folks. Rusty here. Let’s have a look at what’s lined up for Cape Mendocino. I’ll be straight with you – this forecast is a tough one. The water is sitting at a chilly 51°, which is a whopping 5° colder than normal for this time of year. That’s properly unusual, so you’ll want a thick hood and gloves.

The first few days are a write-off. Through Wednesday and Thursday, we’re looking at a cross-shore wind that’s just ruining things. The swell is there, but the quality is poor. Don’t bother paddling out on the 8th or 9th.

Friday the 10th through to Tuesday the 15th is a long gap of nothing. The wind stays onshore or cross-shore, and the wave comment is consistently “poor surf conditions.” It’s just not happening. The swell energy is weak, usually in the 300 to 500 range, and it’s a messy mix.

Things *might* get a little interesting around Wednesday the 16th, but even then, the wind is still a fresh cross-shore, and the wave comment is still poor. There’s a long-period groundswell from the WNW with a period of 20 seconds on the morning of the 16th, but that’s a very long period for a beach break like this, so it’ll likely be too straight and hard to handle. The combined energy hits 645, so there’s some power, but it’s not clean.

The only real glimmer in this entire 16-day window is Thursday the 23rd. The morning shows a solid 5 ft swell from the NW, with a moderate cross-shore, and the energy is well into the moderate range at 1021. The wave comment is still only “marginal,” but it’s the best we’ve got. The afternoon bumps up to 6 ft from the NW, but the period drops to 10 seconds, and it’s still a cross-shore mess. For a spot that’s fairly consistent, this is a disappointing run. It’s a blank spell that’s normal for this area when the wind gods aren’t playing ball.

Keep the board on the roof, but don’t hold your breath. The forecast can change, but right now, it’s a waiting game.

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.
