The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer for The Fort.
Honestly, the next couple of weeks are a bit of a struggle. The Fort is a consistent reef break and it’s fairly exposed to the SW swell, which is the direction it wants, but the wind just won’t cooperate. For the first several days, we’re looking at cross-shore or cross-onshore breezes that are chopping things up. There are a few sessions where the wind eases off, and that’s where the only glimmer of hope is. The water temp is sitting at 59°, which is pretty much what you’d expect for this time of year – nothing weird there.
The best window looks to be early on, Wednesday morning the 9th. It’s small, with 2ft of SW groundswell rolling in at a long 19 seconds, giving it that deep-ocean push. The combined wave energy is moderate at 364. The wind is only 3 mph from the west, so it’s just a light cross-onshore. It’ll be a little bumpy, but for a reef break, that’s manageable. This is the most likely time you’ll get a clean-ish wave, even if it’s not big. It’s a consistent spot, but you might see a few others out.
After that, the wind picks up and stays messy right through the weekend and into the start of the next week. The swell bumps up to 4ft by Monday the 14th, with a short period of 9 seconds from the WNW, but the cross-onshore wind is back and it’s just not going to be pretty. That moderate energy (366) doesn’t help when the surface is all chopped out.
There’s a long dry spell after that where it’s all poor surf conditions. By Wednesday the 16th, we get a tiny 1ft SW groundswell with a very long 16-second period, and finally a true offshore wind from the SW at 3 mph. The energy is weak (132), but that offshore breeze will make the little lines glassy. It’s a tough call – if you’re desperate and have a longboard, you might get a couple of clean little ones.
The second week drags on with more of the same. Slight improvements on Monday the 21st and Tuesday the 22nd, with 2ft to 3ft SW swell and light winds, giving marginal surf. The energy is moderate (337 to 429), but the wind is just off enough to be annoying. Nothing really stands out as a must-go session.
The wind just gets too strong again from the 23rd onwards, with fresh breezes ruining anything that might have been.
So, if you’re keen, aim for Wednesday morning the 9th for the cleanest chance at a wave, or maybe a longboard session on Wednesday the 16th if the offshore wind holds. It’s not epic, but it’s what we’ve got.
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.
