The Lowdown

Right then, grab a coffee and let’s look at what’s coming up for The Fort. This is a reef break, intermediate-friendly, and it’s exposed to the southwest swell. Over the next 16 days, it’s a tough run. The water temperature is sitting about average for this time of year, so nothing unusual there.

The overall pattern is a long, drawn-out period of small, messy swell with a constant cross or cross-onshore breeze. The combined swell energy is moderate, bouncing around the 400 to 700 mark, but it’s never clean enough to get excited about. The swell is a long-period groundswell from the SW, which is the right direction for this spot, with periods stretching from 14 to 19 seconds, but the wind just won’t cooperate.

We start off Friday, August 28th, with a tiny 2ft SW swell. The morning is a write-off with a cross-on wind, and the afternoon gets worse with a cross breeze and a moderate cross-chop. Saturday the 29th sees a slight bump to 3ft, but the cross wind is moderate to fresh, turning the surface lumpy. Sunday the 30th is slightly better with a 3ft swell and a lighter cross-on breeze, but it’s still not clean. Monday the 31st afternoon looks like the only real highlight in the first week. The wind swings to the south and goes light offshore, with a 3ft SSW swell. The combined energy is moderate (322), and the period is a long 14 seconds. That’s the cleanest window in the whole run, but the swell is small. It’s a marginal window, but for a reef break with that light offshore wind, it might offer a few fun, glassy runners for the intermediate crew.

After that, it’s a grim grind. From Tuesday, September 1st, right through to the end of the second week, the story is the same: swell sizes hover between 2ft and 3ft, with periods dropping to 12-13 seconds, and the wind is almost always a cross-on or cross breeze. The combined energy stays moderate, ranging from 189 to 630, but the quality is consistently poor. There is a brief flicker on Thursday, September 3rd morning with a 3ft SW swell and a 19-second period, but the cross-on wind spoils it. The morning of Wednesday, September 9th also shows a 2ft SW swell with a long 18-second period and light cross-on wind, but it’s again marginal. The best of the second week is probably that Saturday, September 12th morning, with a 3ft SW swell, a 14-second period, and a light cross breeze, but it’s only a marginal offering.

The standout, if you can call it that, is Monday afternoon, August 31st. It’s the only time the wind goes offshore and light. For a reef break, that’s golden, but the swell is small. If you’re an intermediate who loves a clean, small wave, that’s your window. The rest of the run is a washout. The Fort is consistent, but it needs a clean wind window to shine, and it’s just not getting one. For a few days there, with the chop and the fresh wind, it’d be more interesting for a kite surfer than a paddle surfer.

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.
