The Lowdown
Alright, let’s be straight about The Fort. Reef break, intermediate level, consistent most of the time—but this whole stretch looks grim. Water’s at 56°F, which is a bit under the norm for this time of year. Not a huge deal, but you’ll notice it on the paddle out.
The full 16-day forecast has no real surf on the cards. The first days are dead—flat, onshore junk, and nothing worth wetting a suit for. Friday the 7th and Saturday the 8th are just a waste. The combined energy is weak, under 250. You’re staring at a long empty period.
Sunday the 9th brings a spike in energy, up to 1107, but it’s short-period and wired with cross-shore wind at 30 km/h. It’s messy, lumpy, and not surfable. Unless you’ve got a kite, leave it.
Monday the 10th through Thursday the 14th: small waves, 1ft to 3ft, with periods mostly in the 8-10 second range. The energy is weak to moderate, and the wind is either light cross-on or just enough to make it choppy. A few mornings have that glassy feel, but there’s no push behind the swell. Nothing to work with.
Friday the 14th into the weekend, the swell stays small—2ft to 3ft—but the periods stretch out to 15-19 seconds. That’s proper groundswell, but it’s tiny. Energy readings are moderate, peaking around 526 on Sunday the 16th. Still, light onshore winds just kill the quality. The Fort needs size, and it’s not getting any.
The second week is more of the same. Swell stays between 2ft and 4ft. Longest period is 19 seconds, but that’s useless with that little height. Most days have cross-on or cross-shore winds, and by the 20th and 21st, it’s blowing 30 km/h again—lumpy, chaotic, horrible.
There’s no standout day. The best shot might be the early mornings on the 15th or 16th, when the wind is light and there’s a bit more consistency in that long-period swell. But it’s still marginal. Don’t get excited.
The Fort is just not working. For this spot, that’s a normal blank spell when the swell direction is all over the place and the wind won’t cooperate. It can change, but right now you’re better off taking a break. Forecasts can shift, so keep an eye out.

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.
