The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin' at Fortress over the next couple of weeks.
Straight up, this is a lean stretch. There’s a real gap at the start of the period with no surf worth paddling out for. The first couple of days have some small swell, but it's just not comin' together. The real action, or lack thereof, drags on. We’re looking at a stretch of over a week with nothing but small, messy, and often windy conditions. It’s not until the morning of Sunday, the 9th of August, that we see a glimmer of something surfable.
For the best of what’s on offer, you’d have to point to Friday morning, the 31st of July. It’s not a classic, but it’s the only window that gives you a bit of hope. The swell is a tiny 3 ft from the SSE, with a period of 9 seconds, giving a combined energy of 114 (moderate). The key here is the wind: it’s dead calm, glassy. That’s a major positive for a break like this. The water is sitting at 69°, which is a bit colder than normal for this time of year. The surf is very ordinary, but if you’re desperate for a slide, that glassy morning might just give you a couple of fun ones. Expect crowds to be possible here, as it’s a spot that’s often got company.
After that, it’s a long, dry run. The swell stays small, the wind is mostly cross or fresh, and the wave energy is weak. The morning of Sunday, the 9th of August, and Monday, the 10th, offer a glimmer of clean conditions with light winds, but the swell is tiny (3 ft to 2 ft) and the energy is low. It’s surfable, but only just. The rest of the second week is a write-off with tiny, weak, and often choppy surf.
Honestly, if you’ve got a kite, the afternoon of Monday, the 3rd of August, with a 4 ft swell and a fresh 22 mph cross wind, looks more interesting for that than for a paddle. The swell is too small and the wind is too strong for a good surf.
Keep your expectations low. This is a blank run that’s pretty normal for the area when the conditions don’t align.
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.
