The Lowdown
Alright, this is Rusty. Let’s have a look at what’s coming up at The Fort.
Alright, straight up, we’ve got a long stretch of nothing much to write home about. For the next couple of weeks, The Fort is pretty much locked in a pattern of cross-shore winds and pretty weak, messy energy. The water is a touch warmer than normal for this time of year, sitting at 60°F, but that’s about the only nice thing going on.
Thursday the 20th and Friday the 21st are just a write-off. Tiny 2ft swell from the SSW, cross-shore winds, and the combined energy is weak in the 200s. It’s just poor surf conditions. Saturday the 22nd gets a little bump in height with a 4ft WNW swell in the afternoon, but the period is a shocking 5 seconds and the wind is a fresh 19 mph cross-shore. That’s just lumpy, gutless junk. Good for a kite maybe, not for a paddle.
We drift through the rest of the week with the same story. Swell from the SW or SSW, mostly under 3ft, and cross-shore winds. The combined energy climbs a bit, hitting 745 on the 29th, but the wind is still on it. A few mornings show a score of 1, but it’s only “marginal” at best – questionable tide or just not enough quality.
The real tease comes at the end of the run. On the morning of the 4th of September, the forecast flips. We get a 6ft swell from the WNW with an 11-second period, and the wind goes glassy. That’s the good stuff. The combined energy jumps to 1937, which is proper strong. This is the standout. It’s excellent for experienced surfers. The Fort is a reef, so a long-period groundswell like this (over 11 seconds) will wrap in nicely, giving you proper shaped waves. The afternoon stays clean with a light cross-shore, but the swell drops a touch to 6ft. This is the one to circle on the calendar, but it’s a long way out, so keep your fingers crossed.
For the rest of the run, it’s pretty grim. There’s a gap of nearly two weeks of poor to marginal conditions before that Friday morning comes alive. Keep the faith.
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.
