The Lowdown

G’day, Rusty here, lookin’ at the surf for The Fort. It’s a reef break that’s fairly exposed to the south-west, and it’s got a consistent track record. The water temperature is sittin’ about average for this time of year, so no surprises there.

The next 16 days are a bit of a mixed bag, but there’s one standout session that’ll get you out of bed. The rest of the run is mostly poor or marginal, so you’ll need to pick your moments.

The action kicks off Saturday the 29th of August with a small 3ft swell from the SW, but a cross-shore breeze of 12 mph messes it up. The combined energy is moderate at 721. It’s a write-off, really. Sunday the 30th morning sees a little improvement with a light WSW offshore breeze of 6 mph and a 3ft SW swell (combined energy 618), but it’s still a marginal call. Monday the 31st morning is similar, with offshore winds again but the swell drops to 3ft. The rest of the first week into early September is a long stretch of poor conditions with small, weak swells and cross-onshore winds.

Now, hold onto your board – Thursday the 3rd of September afternoon brings a jump. The swell kicks up to 5ft from the WNW, with a period of 14 seconds, and the combined energy jumps to 1255 (strong energy). The wind is cross-shore at 12 mph, so it’s a bit lumpy but the size is there – this one’s for the experts only, as it’s pushin’ over 5ft. Friday the 4th of September morning has a 3ft SW swell with a long 18-second period, combined energy 866 (moderate), but the wind is cross-onshore, so it’s still marginal.

The best of the bunch lands on Tuesday the 8th of September morning. The swell is 3ft from the SSW with a 13-second period, and the combined energy is moderate at 445. But the real story is the wind – it’s glassy, with a slight 3 mph breeze. That’s clean, lined-up waves at a reef break, perfect for intermediates. The direction is close to the optimum SW, so it’s a solid, honest little swell. That’s the one to point your car at.

After that, it fades out. Wednesday the 9th of September morning has a 3ft S swell with a short 9-second period, and the wind is cross-onshore. The rest of the run through to Sunday the 13th of September is mostly poor, with small swells and cross-shore or cross-onshore winds. The last session on the 13th morning has a tiny 1ft SW swell with a long 18-second period but combined energy of only 331 (weak) and a moderate cross-shore breeze.

Signing off, 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.
