Table - best surf conditions forecast for Fortress over the next 16 days.


Alright, Rusty here. Let’s talk about the surf situation for Fortress. I’m gonna be straight with you – it’s looking pretty grim for a long stretch. We’ve got a solid 16-day window, but the first real chance of anything worth paddling out for doesn’t show up until the very end.

Right from the start, on Sunday the 12th of July, it’s flat and messy. Tiny, weak swell around 1 ft to 1 ft from the south, with periods that are short and fat. The wind is all over the place, mostly cross-onshore, so the surface is chopped up. No energy at all – the combined swell energy is a measly 33 (weak energy). That’s a no-go.

This poor run hangs around for over two weeks. Day after day – Monday, Tuesday, Wednesday, all the way through the weekend and into the next week – we’re looking at tiny, weak, short-period swell. The wind isn’t kind either, mostly cross or cross-off, occasionally offshore, but the swell is just too small to do anything with. The energy numbers stay in the weak range, barely cracking 100. There’s a couple of glassy moments on the 18th of July, but the swell is only 0.3 ft – you could surf it on a bodyboard and still be bored.

By the 19th, we see a slight bump up to 3 ft, but it’s choppy and onshore. The energy finally hits 131 (moderate) on the 19th afternoon, but the wind is on it and the period is short (7 seconds). It’s a no from me.

The 20th through the 24th are all similar – waist-high and below, with messy winds and weak energy. The swell direction is consistently from the south or southeast, which is fine for Fortress (its optimum is SE), but there’s just no power behind it.

Finally, we get a flicker of hope on Monday the 27th of July. The morning shows a jump in swell to 5 ft from the south, with a period of 8 seconds. The combined energy hits 252 (moderate wave energy). And the wind? It’s glassy – dead calm, east at 3 mph. That is the standout in this whole outlook. The forecast even says “expect good surf conditions” with a score that suggests it’ll be a decent session. That’s the one to circle on the calendar. The water temperature is about average for the time of year, so no surprises there.

But before that, it’s a long, long wait. There’s a gap of about 15 days of nothing worth mentioning. For a reef break that’s fairly consistent, this is a tough run, but it won’t stay poor forever. Keep an eye on that Monday the 27th – it’s the only real chance, and with glassy conditions, it could be a gem.

Rusty, out.

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.
