The Lowdown
Alright, folks. Rusty here. Let’s break down what’s happening at The Fort. It’s a slow start, so don’t get your hopes up too high too soon.
The first real chance to get wet comes on Wednesday the 9th of September. The morning is glassy, dead calm, with a tiny 2ft swell from the SW. But don’t let the size fool you – that swell has a period of 19 seconds, which is proper groundswell energy. The combined energy is moderate at 354. It’s small, but it’ll be clean. The water temp is about 59°F, which is normal for now.
The standout session is Monday the 14th of September. The morning is glassy again, and we’ve got a 5ft swell from the WNW. That’s a solid bump. The combined energy is strong at 664, so there’s plenty of power. It’s a short-period swell at 8 seconds, so it won’t be the most perfect shape, but in those clean conditions, it’ll be a blast. Expect some company.
Another one to watch is Tuesday the 22nd of September. The morning is glassy, with a 5ft swell from the W at 11 seconds. The combined energy is very strong at 759. That’s a promising long-range signal, but it’s two weeks out, so keep your fingers crossed.
The rest of the period is a write-off. From the 10th through the 13th, it’s all cross-shore winds and lumpy, poor surf. The Fort is a consistent reef, but it needs a break in the wind to really shine.
Bottom line: Monday 14th morning is the one to circle. The 22nd morning is a hopeful long-range look. Everything else, just wait.
Rusty.

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.
