The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the Fortress over the next couple of weeks.
First up, the water is running much colder than normal for this time of year, sitting at 66°F with a -3°F anomaly. That’s a solid reminder to pack a thicker wetsuit or a hood if you’ve got one.
The overall pattern is pretty grim for a long stretch. We’ve got a whole heap of days with poor surf conditions and low energy. The combined swell energy is weak, often under 100, and the wind is generally cross-on or messy. It’s a bit of a write-off from Tuesday 21 July right through to the start of August.
The first real glimmer of hope comes on the morning of Monday 3 August. That’s the standout. The swell builds to 5ft from the SSE with a period of 9 seconds, giving a moderate combined energy of 387. The wind is offshore from the WNW at just 12 mph, and the report says clean. That’s the one to aim for. The afternoon picks up even more size, hitting 7ft from the S with a short period of 8 seconds and a strong combined energy of 837. That’s getting solid – a bit too much for beginners, but for the more experienced crew, it’s looking good. The reef setup at Fortress should handle that longer period swell just fine.
Before that, you’re looking at a long, quiet spell. The morning of Thursday 30 July offers a bit of a tease with 3ft from the SSE and offshore wind, but the energy is only moderate at 163 and it’s only rated as ordinary. Nothing special.
So, to sum it up: don’t bother paddling out until the end of the first week of August. Clear your schedule for Monday 3 August – that’s your best bet. It’s a long way out, so keep an eye on it, but it’s the only real highlight in the whole outlook.
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.
