The Lowdown

Right, let’s have a look at what’s on offer. The whole window’s looking pretty flat and messy for the most part – there’s no proper surf coming through for a good stretch. The first real chance of anything worth paddling out for doesn’t show up until Tuesday the 4th of August, and even then it’s not gonna set the world on fire. We’re looking at a solid gap of a couple of days with absolutely nothing before that.

The only spot in the game is Fortress, a reef break that’s fairly consistent but needs a bit of love from the swell direction. It’s exposed to the S and SE, and the optimum swell direction is from the SE, so we’re mostly seeing short-period, average-sized S swell, which isn’t ideal.

The standout moment in this whole 16-day outlook is Tuesday morning, the 4th of August. The wind drops right out – glassy conditions, with a light NW breeze (5 km/h). That’s a major positive. Swell is 4ft from the S, with a period of 8 seconds, giving a combined energy of 177 (moderate). The water’s sitting at 69°, which is a bit colder than normal for this time of year. It’s not a big, powerful swell, but it’s clean and glassy, and that’s about as good as it gets in this run. The afternoon holds up with a clean, cross-off breeze and a 3ft swell, but the morning glass is the pick.

For the rest of the period, it’s a bit of a write-off. The wind is howling from the SSW on the 3rd (up to 28 mph), with a 7ft cross-shore mess (combined energy 582 – strong). That’s experts-only territory, and even then, the wind is gonna make it a battle. There’s a brief clean window on the 10th with 6ft swell and a cross-off breeze, but the wind is up to 28 mph again, so it’s more of a kite-surfing scene than a paddle session. The rest of the days are tiny, onshore, or just plain poor.

Honestly, if you’re keen, the 4th is your only real shot. After that, it’s a long, dry spell. The forecast can always change, but for now, it’s a quiet one at Fortress.

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.
