Table - best surf conditions forecast for Fortress over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what the next couple of weeks are serving up. I gotta be straight with you – it’s a grim run ahead. The whole 16-day window is basically a bust for any proper surfing. There’s one tiny glimmer way out, but we’ve got a long, flat wait to get there.
From now through to the 21st of July, it’s a write-off. The swell is tiny, the wind is mostly on it or cross, and the energy is pathetic. The combined wave energy barely cracks 100 for most of it, sitting at 22 (combined energy of all swells directed here) on the morning of the 13th. We’re talking knee-high dribble with short, weak periods. Even when the wind goes glassy on the 15th, there’s no swell to push. You’re looking at a solid 9-day gap with zero reason to paddle out. It’s the kind of stretch that tests your patience.
Now, heads up for Wednesday, the 22nd of July. It ain’t a classic, but it’s the only thing on the menu. Fortress (a reef break) will see a slight lift. The morning has a gentle offshore wind from the WNW, which is a positive for clean faces, and the swell will be 4 ft from the S. The period is short at 8 seconds, so it won't be anything special, but the combined energy does bump up to 179 (combined energy of all swells directed here), which is moderate. The afternoon gets a little bigger, with the swell pushing 5 ft from the S and the energy jumping to 401 (combined energy of all swells directed here), but the wind swings to a cross-off. Still, it’s classed as “marginal surf” and "questionable tide conditions". It’s a last resort for a desperate surfer, and you’ll likely have it to yourself because nobody else is bothering. That bigger afternoon swell, at 5 ft, is getting into the territory where it might be a bit much for beginners at this spot, but still manageable for most intermediates.
After that little blip, it’s back to flat nothing through the end of the month. The 24th of July shows some stronger onshore winds and lumpy conditions, not worth a look. So, there you have it. One spot, one day, with some clean(ish) but underwhelming waves. Hang in there.
Stay patient,
Rusty

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.
