The Lowdown
G’day, Rusty here. Let’s be straight with you – it's a pretty bleak run ahead for The Fort. This reef break is consistent, but the 16-day window is full of poor surf conditions and only a few glimmers that are barely worth a mention. There’s a massive gap of almost nothing worthwhile from now until late in the period, so don’t get your hopes up early.
Looking at the overall pattern, we’ve got a persistent stretch of cross-shore and cross-onshore winds, mostly moderate to fresh, mixing up the surface with lumpy chop. The swell sticks around the 2 ft to 5 ft range for most of it, with moderate wave energy (combined energy mostly between 172 and 434). It’s mostly a short-period, weak offering that won’t shape up well here.
The only surf that might tempt you comes right at the end. On Saturday, September 26, the afternoon session sees a jump to 7 ft from the NW with an 11-second period – that’s moderate wave energy (1615) and it’s a strong push. But the wind is a fresh cross-shore NW at 35 km/h (22 mph), so it’ll be lumpy and choppy. That size is only for experts, and The Fort is a reef, so you’ll want plenty of experience. The next morning, Sunday, September 27, there’s a drop to 4 ft from the WNW with a 10-second period, lighter cross-on wind at 10 km/h (6 mph), and moderate energy (515). It’s still marginal, but that’s the cleanest option all window.
There is one odd moment: Wednesday, September 16, in the afternoon you get glassy conditions with a tiny 2 ft SW swell and a very long 17-second period (combined energy 236). That’s a glassy surface, which is rare, but the swell is tiny and that long period will make it straight and hard to ride on a beach setup – The Fort is a reef, so maybe a few long walls, but don’t expect much.
No standout here. The best on offer is that Sunday morning, September 27, with the 4 ft WNW swell and light cross-on wind – it’s the most likely to give you a few cleanish lefts. But honestly, the whole window is a write-off for quality. The water temperature is about average for this time of year, no anomaly to report.
Forget the rest of the fortnight – it’s a poor run.
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.
