The Lowdown
Alright, Rusty here again. Let’s break down the next couple weeks at The Fort.
First thing you’ll notice – the water’s running a bit cold, about 57°, which is a degree or so cooler than normal for this time of year. You’ll want a thicker suit.
To be honest, the first week and a half is pretty rough. We’ve got swell in the water, with moderate combined energy mostly between 200 and 600, but the wind is the enemy. It’s cross-onshore or cross-shore most of the time, leaving the surface choppy and lumpy. There’s a pulse of longer-period energy from the SW around the 3rd and 4th, with energy readings of 560 and 582, but that WNW wind ruins any chance of it cleaning up. A few mornings, like Saturday the 5th with a light onshore, or Monday the 7th, are described as "marginal," but nothing worth writing home about.
Now, if you’re hanging in there, there’s one clear standout. Thursday, September the 10th. Morning is clear with a light cross-onshore breeze, and the swell jumps. We’re looking at surf around 4-5 ft from the WNW, with an 11-second period, and the combined energy hits a strong 814 – that’s some proper power. The afternoon holds similar size at about 5 ft, though the wind is a bit more cross-shore, but it’s still your best shot. That day is the real highlight.
After that, it fades. The 11th still has some waist-to-chest high leftovers from the WNW, but energy drops to around 400-500. From the 12th onward, it’s small, weak swell with poor wind conditions again.
So, it’s a long wait for one solid Thursday. Most of this stretch is a dud, but that 10th? If you can make it, keep an eye on the tide.
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.
