The Lowdown

Alright, folks, Rusty here. Let’s talk about what’s cookin’ at Timber Cove. I gotta be straight with you – the next week and a half is a real tough slog. We’ve got a long stretch of nothing but poor surf conditions and cross-shore winds that just won’t let up. The swell is all over the place, short period, and messy. It’s a frustrating wait.

Look, the first few days are a total write-off. Friday the 21st through the end of the month is just a parade of weak, jumbled swells. You’ll see a northwest swell bump up on Saturday the 22nd afternoon, but it’s a short, choppy 4ft with a nasty 5-second period, which is just gonna be a crumbly mess. The wind is mostly cross-shore and fresh, so it’s gonna be lumpy. The combined swell energy is moderate at best, but it’s just not coming together. We’re lookin’ at a solid 10-day gap where you’re better off finding a new hobby.

Now, if you’ve got patience, the real hope is sitting way out there on the horizon. As we kick off September, things start to change. The morning of Wednesday the 2nd of September shows a jump in size – 7ft from the WNW with a period of 8 seconds. The combined energy jumps to strong (1056). The wind is light from the WNW, giving us a clean glassy cross-shore. That’s the first real glimmer of life. The swell is still a bit short in period, but the size and clean wind make it a far better bet.

But the real standout, the one that has my blood pumping, is the morning of Thursday the 3rd of September. We’re looking at a solid 8ft from the WNW with a period of 10 seconds. The combined energy is a massive 2521. That’s a serious groundswell packing a ton of power. The wind is a moderate cross-shore from the WNW, keeping things reasonably clean. This is expert territory all the way – that size at Timber Cove is no joke, and it’s going to be a heavy, powerful wave. The quality is still only marginal, but for this stretch of the forecast, it’s the best on offer by a long shot. The swell is mostly cross-shore, but the size and energy will produce some proper walls. Just be mindful of the crowd – it’s a consistent spot and the word will be out.

So, the takeaway for Timber Cove: suffer through the next week and a half. The water temperature is about average for the time of year. The real action, the one that’s worth pointing your car at, is that Thursday morning (3rd of September). It’s big, it’s powerful, and it’s the only real pulse in this whole outlook. Get on it if you’re an experienced surfer. For everyone else, wait for a better day.

Rusty.

Information about the Timber Cove Surf forecast

The above surf forecast table for Timber Cove provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Timber Cove can be found by selecting the local surf guide option on the grey menu. Our Timber Cove 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 (Timber Cove) 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 Timber Cove 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.

Timber Cove is 40 km (25 miles) from the city of Windsor. If you plan a vacation in Sonoma County, look for hotels and other accommodation in Windsor. Windsor has rooms for a wide range of budgets as well as car hire and transport links.
