The Lowdown

Alright folks, Rusty here. Let's take a look at what's on the table for the Fortress.

Straight up, I’m not gonna sugar-coat it: this 16-day window is a tough one. We’ve got a real dry spell on our hands. The first solid week is pretty much a write-off, with nothing but small, weak, and messy conditions. The water temp is sitting pretty average for the time of year, nothing to write home about.

From Thursday the 27th right through the following Wednesday, we’re looking at a lot of cross-shore wind and tiny swell. The swell energy is super weak, never getting above 96 (71-96) for most of that stretch. A few moments on the 28th morning and 30th morning show a bit of a cleaner look with cross-offshore winds, but the waves are just too small and weak to get excited about – 1ft to 2ft from the SE with a short, weak period. It’s a real struggle.

We do get a brief glimmer of hope on Monday the 31st morning. The wind goes glassy, which is a massive positive, and the swell bumps up to 3ft from the SSE. The energy is still low (68) and the period is short (5s), but it’s the first time we get a “surfable” tag. Still, very ordinary.

Then the wind turns nasty. From Tuesday the 1st of September, we get a solid easterly wind event that just wrecks everything. The swell actually builds a bit, but it’s all onshore and blown out. By Wednesday the 2nd, the swell hits 5ft from the east with a near gale cross-onshore – that’s kite-surfing territory, not paddle surfing. The energy climbs to 214 (moderate), but it’s ugly.

The biggest swell of the window hits on Thursday the 3rd of September, with 8ft from the east. That’s serious size, but it’s cross-onshore and choppy, and the energy is strong (853). This is strictly for experts only, and even then, the wind is a dealbreaker. The following days see that swell slowly drop, but the onshore wind sticks around, keeping it messy and lumpy right through to the 7th.

We get another little breather on Tuesday the 8th of September. The wind goes light and cross-offshore from the west, and we get 4ft to 5ft from the SSE. The energy is still low (95-115), and the period is short (5-6s), but it’s clean. It’s surfable, but very ordinary.

The final few days, from the 9th to the 11th, just fade back into tiny, weak, and mostly choppy or glassy but flat conditions. The 10th morning is glassy, but with only 1ft on offer, it’s a tough paddle for nothing.

The standout? Honestly, there isn’t a proper standout. If I had to pick the best of a bad bunch, it’s a toss-up between Monday the 31st morning for the glassy conditions and the 3ft swell, or Tuesday the 8th of September for the clean 4ft to 5ft from the SSE. Of those two, the 8th probably offers the most size and shape, albeit still very ordinary. The 31st is smaller but glassy. Both are weak, short-period swells, so don’t expect any power.

Alright, keep your eyes on the forecast, because this run of poor surf can’t last forever. This is Rusty, signing off.

Information about the Fortress Surf forecast

The above surf forecast table for Fortress provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Fortress can be found by selecting the local surf guide option on the grey menu. Our Fortress 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 (Fortress) 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 Fortress 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.

Fortress is 39 km (24 miles) from New London. If you plan a vacation in Long Island New York, look for hotels and other accommodation in New London. New London has rooms for a wide range of budgets as well as car hire and transport links.
