The Lowdown
Alright, crew, Rusty here. Let’s break down the next couple of weeks for the local zone. It’s looking pretty flat and gnarly for the most part.
We’ve got a big gap of several days with no real waves to speak of. The first glimmer of hope comes around the weekend of August 15th, and even then, it’s touch and go.
The best bet is the 15th and 16th of August. The Fort (reef, consistent) picks up a pulse from the southwest. On Saturday morning the 15th, expect some long-period groundswell at 3ft from the SW, with a period of 17 seconds. The wind is light and cross-onshore, so it’ll be a bit bumpy, but the energy is moderate (459). The water temp is about 57°F, which is pretty normal for this time of year. The real standout is Saturday afternoon the 15th, with a light offshore wind from the SSW, 3ft of SW swell with a 16-second period, and a clean glassy surface. The energy is still moderate (377). That’s the best session of the whole run. On Sunday the 16th, the morning has light cross-on winds, 3ft SW swell at 16 seconds, energy (456), but it’s not as clean. The afternoon on the 16th shows a similar 3ft SW swell with a light cross-on breeze, energy (376). These are the only sessions worth a look, but they’re not firing.
After that, the run into the 23rd of August is a mess of poor surf conditions with moderate to fresh cross-shore winds, choppy water, and blown-out waves. There’s a spike in energy on the 20th of August with 5ft of WNW swell and a combined energy of 640, but it’s accompanied by a fresh cross-shore wind of 19 mph, making it a lumpy, churned-up mess. That’s a kite-surfing day, not a paddle session.
Bottom line: keep your expectations low. The only real window is that Saturday to Sunday, 15th-16th of August, with the best chance being the glassy afternoon on the 15th.
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.
