The Lowdown

Imperial version

Hey, Rusty here. Look, The Fort (reef break, intermediate) is usually a consistent spot, but this 16-day run is a real letdown. We're starting off with nothing—Monday afternoon is small, messy 4ft of WNW swell with a cross breeze, and the water temp sits at 59°, right on average for this time of year. Tuesday morning has a brief offshore but waves are barely 3ft and unrideable. Wednesday cranks up to 6ft but it's cross-shore and lumpy—still no good. Thursday and Friday mornings sneak in a tiny 2ft SW groundswell with long 16–19s periods, but it's marginal at best, and cross-onshore wind keeps it clean only in patches. That's about the only faint glimmer in the first week.

Then we hit a flat patch from Saturday the 19th through Sunday the 27th—days of small 2–2ft SW swell, mostly cross or onshore winds, and energy readings bouncing between 200 and 600 (moderate but poorly aligned). There's a slight spike on Monday the 21st afternoon with 6ft NW swell and combined energy 1036, but cross wind and moderate chop spoil it.

The real standout—and it's a long-range one—is Tuesday the 29th of September morning. That morning brings 7ft of WNW swell with 10-second period and a light cross breeze (offshore would be better, but it's still glassy-ish). The combined energy hits 1338 (strong), and for an intermediate reef break that's decent. The direction isn't the optimum SW, but the size and slight offshore-ish wind could line up some clean walls. That said, it's over 5ft so not for beginners, and the forecast has marginal surf concerns—so don't book your flight yet. A promising but uncertain option way down the line.

Overall, there's a long dry stretch from now until the 29th, with only a few marginal windows. The Fort can handle swell, but this pattern isn't delivering. Unless you're a die-hard, I'd keep an eye on that last Tuesday morning and hope the wind swings more favourable. 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.
