The Lowdown
Alright folks, Rusty here. Let's get into it.
Well, it’s a pretty tough run ahead for The Fort. Looking at the whole 16-day window, we’ve got a solid block of days with very little surf worth paddling out for. In fact, the outlook is grim right from the start. There’s a long stretch of marginal to poor conditions, and we don't see anything firing until the very end of the window.
The Overall Pattern
The wind is the big problem. It’s hanging in the WNW – NW quadrant constantly, which is a cross to cross-onshore breeze for this southwest-facing reef. That's putting chop and bump all over whatever little swell we have. The surf stays small, mostly under 3 feet, and a lot of the time it's just plain messy.
Friday 14th August kicks things off with a tiny 2ft SW swell, but that cross-shore breeze is already messing it up. Combined swell energy is weak (355). Not one to get excited about.
From Saturday 15th through to Sunday 24th August, it's a desert. There are a few mornings with a bit of waist-high SW swell – like 3ft on the 15th and 16th, and 3ft on the 17th – but the wind is always on it or cross-on, leaving the surface chopped. The combined swell energy is barely reaching moderate levels, and the wave comments say it all: "marginal" or "poor." You’d be fighting bump and wind the whole time. These are days to stay on land.
Around Tuesday 25th August, the swell bumps up a bit with 6ft from the WNW, but the period is a short, weak 8 seconds. The energy is moderate at best (643), but a 15-18 mph cross-shore wind is tearing it up again. That’s not surf; that’s a washing machine.
The Standout (and it’s a long-range one)
The only time I’d even consider waxing a board is for the Friday morning of the 28th August. We see a bit of a pulse: a 5ft swell from the NW with a 9-second period. The combined energy jumps to a solid moderate 937. What makes this interesting is the morning wind is light from the NW, not hammering it. It’s cross-on, so not perfect, but light enough that there might be some cleaner moments between sets at The Fort. This swell direction (NW) is a bit off the optimum SW, but it will wrap in. Because it’s over a week out, treat this with caution – a long-range promise that could easily change.
The Breakdown
Let’s be honest: there are no real standouts in the first two weeks. The water temp on the 14th is sitting at 58°F, which is perfectly average for this time of year. The real issue is the persistent wind and lack of decent consistency. For a spot that’s described as consistent, this blank run is a surprise, but the wind is just making it impossible to get a clean wave.
A lot of these days with small, weak swell and a strong cross-shore breeze? That’s more kite-surfing weather than proper paddle surfing.
To sum it up: The Fort is a no-go zone for the next ten days. Everything is too small, wind-affected, or both. The only flicker of hope is the morning of Friday 28th August, but lock it in lightly.
Stay patient, stay dry.

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.
