The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for The Fort over the next couple of weeks.
Right off the bat, truth be told, the first few days are a bit of a write-off. We’ve got a bit of a lull to start the forecast period. The water is sitting at 57°F which is a notch colder than usual for this time of year, so you’ll be wantin’ a decent suit.
We don’t really see anything worth paddling out for until Thursday the 3rd of September. That morning the stars nearly align – glassy conditions with the wind swinging light out of the SE at just 3 mph, and a clean 2ft swell from the SSW. The swell period is a solid 19 seconds, which is proper long-period groundswell, so it’ll have some real push. The combined energy is strong (645), but with that long period, it might be a bit straight for a beach break; this reef setup at The Fort (The Fort) should be handling it nicely. It’s a consistent spot, so you know there’ll be waves, but it can get crowded sometimes. Thursday is the standout in this whole outlook; it’s the best we’re gonna see.
Things get a bit marginal after that. Friday the 4th still has a bit of size on the 3ft SW swell, but the wind is cross-onshore from the W, so it’s not as clean. The energy is still strong (698), but the wind is gonna mess with the surface.
We have a long stretch of average to poor conditions right through until Saturday the 12th of September. That afternoon things finally look tidy again. The wind drops to glassy out of the SW at 3 mph, and we get a clean 3ft from the SW with a 14-second period. The energy is moderate (285), but the conditions are right. It’s a shallow, clean little window.
Looking way out, Tuesday the 16th of September, the swell jumps up to 7ft from the WNW with a short 9-second period. That’s a lot of water moving, with very strong energy (1057), but it’s going to be a bit of a messy, short-period wall. That size is getting into expert territory, and with the cross-offshore breeze, The Fort could be a bit of a handful. It’s a fringe day for the experienced crew only.
So, for the whole 16 days, the clear winner is Thursday the 3rd morning. Get out there for that glassy dawn patrol.
Rusty, signing off.

Information about the The Fort Surf forecast
The above surf forecast table for The Fort provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Fort can be found by selecting the local surf guide option on the grey menu. Our The Fort 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 (The Fort) 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 The Fort 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.
The Fort is 38 km (24 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.
