The Lowdown
G'day, Rusty here, and I gotta be straight with you – the next two weeks are looking pretty grim for a proper paddle. Based on what I'm seeing, we've got a bit of a wait ahead. The forecast basically kicks off with a blank run, and there's not a real standout session until around Monday, the 3rd of August. That's a good 9 days of mostly poor conditions to sit through, with only a couple of very small, marginal windows.
Let's start with the first slot. Saturday the 25th of July at Fortress (reef) is a write-off. We've got a tiny 3 ft ESE swell, but with a short 7-second period and a cross-on wind from the ENE at 16 mph, it's just choppy and messy. The combined energy is weak at 78, and it's a no-go. That pattern holds through the whole first week – small, short-period swells, mostly onshore or cross-on winds, and the water temp is about average for this time of year. Sunday the 26th isn't any better, and Monday the 27th is flat with a 2 ft swell and just 49 energy. It's heartbreaking.
We get a bit of a spike Wednesday the 29th, with a chunky 6 ft ESE swell, but it's still a short 6-second period and howling onshore at 22 mph. The energy is moderate at 241, but the wind is a mess. It's the same story Thursday morning the 30th – a 6 ft NE swell, but with a strong cross-off wind that's actually cleaning it up, but the period is only 6 seconds, so it's lumpy. Not worth the paddle.
Now, here's the one and only standout. On Monday, the 3rd of August, we finally get a window. The morning at Fortress looks alright – a 4 ft S/SSE swell, but with a long 9-second period and a clean offshore wind from the WNW at 9 mph. The combined energy is moderate at 202, and the wind is gentle offshore, meaning clean conditions. This is the best on offer, but it's still a pretty average day. The swell direction is from the SSE, which is a bit off the optimum SE direction for this spot, so it might not be breaking perfectly. Still, it's the only session with a half-decent score.
After that, it's back to small, weak, and ordinary. The first few days of August are a slow fade. Thursday the 6th has a tiny 3 ft S swell with a 7-second period and a light offshore, but it's just surfable, not exciting. By the second week, from the 7th of August onward, it's flat – 2 ft or less, with almost no energy. The combined energy drops to 19 or 34, and the periods are down to 5 or 6 seconds. It's a long, quiet stretch.
So, to sum it up: if you're desperate, wait for Monday the 3rd of August morning for a clean, small wave. Everything else is a write-off. The water temp is about average for the time of year. This is a tough one.
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.
