The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
First up, the water temp at The Fort is sitting at 59°F and that's bang on average for this time of year, so no surprises there.
Honestly, it's a bit of a slow start. We've got a few days of small, wonky swells to get through. Saturday the 5th and Sunday the 6th are pretty much a write-off with cross-shore winds messing up the small 3ft SSW swell. The energy is there, about moderate, but it's just not coming together cleanly.
Monday morning the 7th is the first real glimmer of hope. The wind swings lightly offshore from the SW at just 3 mph, and we've got a 3ft SSW groundswell running with a long 13-second period. The wave energy is still moderate. It's not going to be pumping, but that light offshore should make it clean and rideable. It's a marginal call, but the best early option.
Wednesday afternoon the 9th is the standout of the first week. The forecast shows clean conditions with a cross-offshore breeze from the NNW at 9 mph. The swell picks up to 3ft from the SSW, but more importantly, the period stays at 11 seconds, and the combined energy is moderate. The wind and swell direction match up nicely for The Fort, and it's a reef break, so that longer period will wrap in nicely. This is your pick for a fun, clean session.
Thursday the 10th sees a slight bump in size, with the swell hitting 4ft from the SSW (period 11-12 seconds). The energy is getting up there, moderate to strong. But the wind is a cross-shore, which will put a bit of a chop on the surface. It's still surfable, but Wednesday afternoon is the cleaner option.
After that, things go downhill. From Friday the 11th right through to the 20th, it's a long stretch of poor to marginal conditions. The wind picks up, the swell drops off, and the energy levels fall away. There are a few pulses of longer period swell (17-20 seconds) in the second week, but they're tiny (1ft to 2ft) and with cross-shore or onshore winds, it's not going to be worth paddling out. The 17th of September has a 5ft WNW swell, but it's a short-period 6-second windswell with a fresh cross-shore wind – that's a lumpy, messy mix that's more for the kites than a surfboard.
So, the call is clear: make the most of Wednesday afternoon, the 9th of September. That's the one clean, rideable window in an otherwise quiet outlook. The swell direction is right for the reef, the wind is right, and it's your best bet for getting a few clean ones.
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.
