The Lowdown
Alright, Rusty here. Let’s talk about what’s cookin’ at The Fort.
Right off the bat, I gotta be straight with you – the next week and a half is pretty flat and frustrating. We’re looking at a long stretch of weak, messy swell with cross or cross-on winds keeping things choppy and uninviting. The water’s sitting at 56°, which is a bit colder than what we usually get this time of year, so don’t forget the extra rubber.
Thursday the 3rd starts off with a weak 2ft SW groundswell (670 energy), but it’s cross-on and the conditions are just marginal. Not worth paddling out for. That theme carries on through to the following Thursday the 10th – lots of small, short-period slop and poor surf quality. It’s a real dry spell, mate.
Now, keep your eyes on Friday the 11th of September. That’s the standout. We’ve got a solid 10ft SW groundswell rolling in, with a healthy 12-second period and a massive 2146 combined energy. That’s proper punch. The morning wind is light cross-on, so it’ll be a bit bumpy, but it’s the biggest swell we’ve seen by a long shot. The Fort is a reef break, so that long-period SW groundswell will wrap in nicely. This is one for the experienced crew – 10ft is not for beginners. The afternoon drops to 7ft, still decent, but the wind picks up and goes cross-shore, so it’ll get messy.
Saturday the 12th still has some size at 5ft in the morning, but the wind is howling cross-shore at 15 mph, turning it into a lumpy, blown-out mess. If you’re not a surfer, the kite crew might be having a field day.
After that, we drop back into tiny, weak surf for the rest of the run. The only glimmer is on Friday the 18th in the afternoon – a glassy 2ft SW swell with 625 energy and perfect conditions. That’s the cleanest, most user-friendly wave of the whole forecast, but it’s tiny. Good for a longboard or a foamie if you’re desperate.
Overall, the best option on offer is that Friday the 11th morning session. Big, powerful, and for experts only. Everything else is a waiting game.
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.
