The Lowdown
Alright, folks, Rusty here. Let’s get into it. The next couple of weeks are a real mixed bag, and to be straight with you, we’ve got a long, quiet patch before anything worth paddling out for shows up. Timber Cove’s the only game in town, but it’s a waiting game.
The outlook kicks off with a tough start. From Friday, the 11th of September, right through to the 22nd, it’s pretty grim. We’ve got a solid 12 days where the surf is either flat, chopped up, or just plain unappealing. The wind is almost always a cross-shore or cross-onshore breeze, and it’s too strong most days to keep things clean. Swells are small, mostly around 1ft to 5ft, and while the period on the SW swells looks decent for shape, the energy is low—moderate (under 685). It’s a stretch where you’re better off doing something else.
The water temperature at Timber Cove is sitting around 59°, which is about average for this time of year, nothing to write home about.
Now, the first real glimmer of hope arrives on Wednesday the 23rd of September. Early morning, the wind goes glassy—absolute perfection—and we see a jump in swell. That WNW groundswell comes in at 6ft, with a relatively short period of 8 seconds and moderate energy (635). It’s a bit on the punchy side for beginners at that size, but for intermediates and up, those clean, glassy conditions will be a treat. The afternoon stays small but clean with a slight cross-on.
Thursday the 24th keeps things interesting. The swell builds a touch more—5ft in the morning and 5ft in the afternoon from the WNW. The period stretches to 12 seconds, which is proper groundswell territory. The energy jumps into the strong zone (740 and 1121). This is a longer-period swell, so it’ll wrap in nicely at Timber Cove, but it might be a bit straight for beach breaks if there were any. Winds are light, with a slight cross-on in the morning and a light cross-shore in the afternoon. This is the standout window: good size, solid energy, clean winds.
Friday the 25th of September is worth a look too. The morning is small, with 3ft and a light cross-on, but the afternoon glassed off again with 3ft. Clean, small waves for a relaxed session.
After that, the swell drops right off again into the weekend. So, if you’re picking your moment, Wednesday the 23rd and Thursday the 24th are your best bets for the best combination of size and clean conditions. Thursday afternoon, with that big energy and light wind, is the one to circle on the calendar. Crowds? Timber Cove’s listed as “often” busy, so expect a few others with the same idea.
Rusty out.

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.
