The Lowdown

Alright folks, Rusty here. Let’s have a look at what The Fort has in store for us over the next couple of weeks.

Right off the bat, I gotta be honest with you – it’s a pretty grim run of surf on the horizon. We’re looking at a long stretch of small, weak swell and mostly dodgy winds. The first session worth even paddling out for doesn’t show up until Monday afternoon, August 10th. That’s a bit of a quiet start. Even then, it’s only a tiny 3ft swell from the WNW with a meagre 9-second period, putting the combined energy at a weak 293. The wind is a light cross-onshore breeze, so it won’t be glassy, but it won’t be a total washing machine either. The water temp is 57°, right about average for this time of year so nothing weird there. Expect a bit of a chop and only the most optimistic surfers will get much out of it.

The rest of the first week is a write-off. Tuesday through Friday are full of poor surf conditions and “marginal” tide calls. You’ll see tiny 1ft to 3ft stuff, but the wind is often onshore or cross-onshore. There’s a brief moment on Friday morning, August 14th with glassy conditions – clear skies and a 3 mph onshore breeze – paired with a 2ft, 15-second groundswell. That long period might offer a few cleaner lines at this reef if you’re desperate, but the energy is low (290) and the score is barely a whisper. It’s not worth the drive unless you’re local and need to get wet.

Now, the one and only true standout in this whole 16-day forecast is the Saturday morning session on August 15th. The swell jumps up to 3ft from the SW with a solid 17-second period. This gives us the highest combined energy of the entire forecast at 462 – still moderate, but it’s got some real push. The wind is light and onshore from the SW at 6 mph, which isn’t perfect, but at a reef like The Fort, that light onshore flow can actually groom the face. This is the best bet for a few proper waves, especially for intermediate surfers. The long period means those sets will have some grunt and space between them, making the paddle out a bit easier.

After that, it’s back to the doldrums. From Sunday, August 16th, right through to Tuesday, August 25th, we see persistent poor conditions. The swell stays small, often under 3ft, and the wind either stays cross or cross-onshore. By the end of the second week, the wind is picking up to fresh breeze levels (15-19 mph) from the NW, making it lumpy and choppy. With the energy numbers dropping into the low 100s and 200s, this setup honestly looks more interesting for a kite surfer than a paddle surfer. Crowds are only “sometimes” a problem here, but with surf this average, you’ll have the place to yourself.

So, in a nutshell: Saturday morning, August 15th is your best shot. The rest is a waiting game. It won’t stay this flat forever, so keep an eye out.

Stay salty,
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.
