The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for Fortress over the next couple of weeks.
Straight up, it's a bit of a slow burn. The opening days are a write-off, with nothing but poor, choppy conditions. You're looking at a solid gap of about four days with no real surf on offer. The swell is small and mostly from the south-east, with a short, weak period, and the wind is all over the shop, cross-shore and cross-onshore, turning the ocean into a washing machine. The combined energy is low, barely cracking 100 (165) on the first day, and it's not a pretty picture.
Things start to look a little more interesting around Tuesday the 28th of July. The morning brings a clean, offshore breeze from the northwest for the first time. The swell is a bumpy 4ft, but it's coming from the SSE with a short period of 6 seconds. The energy is there though, at a moderate 173. It's surfable, but the conditions are ordinary. The water temp is about average for this time of year.
Then, on Thursday the 30th of July, we get a proper window. The morning is glassy, with a light offshore from the WNW. The swell is 3ft from the SSE, with a period of 9 seconds, giving it a bit more shape. The energy is moderate (183). It's clean, it's small, and it's a good option for a beginner-friendly wave. The downside is that Fortress is a reef break that can get crowded often, so expect company.
Looking further out, there's a couple of promising mornings. On Friday the 1st of August, the morning has a clean offshore breeze from the northwest, but the swell drops right off to 2ft. The energy is low (74). It's a tiny, clean wave, maybe for the log.
The standout, though, is Monday the 3rd of August. The morning is glassy, dead calm, with a light breeze from the WNW. The swell is a clean 3ft from the SSE, with an 8-second period, and the combined energy is a moderate 107. It's small, but it will be perfectly clean and fun for a longboard or a fish. This is the best on offer.
Finally, Tuesday the 4th of August has a morning with a light offshore from the WNW again, and a 4ft swell from the south with a 7-second period. The energy is moderate (127). The conditions will be clean, but the swell is a bit short-period and the crowds will be there.
So, the picks are the morning of Thursday the 30th of July for the best balance of size and glass, and the morning of Monday the 3rd of August for the cleanest, smallest conditions. The rest of the window is a mix of small, choppy, and onshore, so don't get your hopes up too high until you see that glassy water.
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.
