Alright folks, Rusty here. Let’s have a look at what’s on the table for Fortress (reef break).

Right off the bat, I gotta be honest with ya – this 16-day window is a tough one. We’re staring down a long, barren run where the surf just isn’t cooperating. The first proper chance to even think about a paddle doesn’t show up until Tuesday, July 7th, and even then, it’s only just squeaking by.

From the start of the period through to the end of the first week, it’s mostly tiny, weak, and messy. Friday the 3rd and Saturday the 4th offer nothing rideable – swells are flat, periods are short, and the energy is pathetic (combined energy at 46 and 13 respectively). Sunday through Monday is the same sad story: onshore wind and tiny waves. It’s a real gap of several days with absolutely nothing worth your time.

Finally, on Tuesday morning, July 7th, we get a tiny glimmer. The wind goes glassy – dead calm – and that’s priceless. The swell is only 3ft from the SE, with a short period of 5 seconds and combined energy of just 71. That’s weak, but glassy conditions at a reef break will make it look better than it is. It’s a "surfable" window for the absolute beginner or someone who just needs to get wet. The water temp anomaly is about average for this time of year, so no surprises in the water temp.

The standout in this entire forecast is Sunday morning, July 12th. We get an offshore breeze (W at 15 km/h) and clean waves. Swell is 3ft from the S with an 8-second period and combined energy of 98 – still moderate, but the wind makes it the cleanest option of the whole stretch. That close-to-offshore flow right into the SE optimum direction for this reef means the waves will have a bit of shape. This is the one session you’d pencil in if you’re desperate.

On Wednesday morning, July 15th, it bumps up a touch – 4ft from the SSW with a 6-second period – but it’s cross-off wind and clean, so it’s okay. Combined energy of 106 shows moderate energy. Still, nothing here is firing.

Tuesday the 14th also has a morning glass-off with 2ft from the S, but it’s gutless (combined energy 64) and short period (8s). It’s surfable for a log, but don’t drive far.

Honestly, for most of this 16-day stretch, the quality is poor. There’s no big groundswell, no long-period juice. The break is fairly consistent, but the conditions rarely line up. If you’re a kiter, those cross-shore afternoons with 3ft to 4ft and moderate breeze might look interesting, but for a surfer, it’s a waiting game.

The only real highlights are Tuesday the 7th for a glassy slide and Sunday the 12th for clean, offshore conditions. Keep your expectations low and your wetsuit handy.

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.
