The Lowdown
Hey folks, Rusty here. Let’s talk about what’s coming up at Fortress. It’s a reef setup that’s fairly consistent with the swell, but honestly, this 16-day window looks pretty quiet overall. We’ve got no decent waves to speak of in the first few days, so don’t bother paddling out yet.
Right off the bat, Sunday the 19th is flat and messy – a tiny 3 ft south swell with weak energy (58) and a moderate breeze making it cross-off. The water’s a bit colder than normal at 68°, sitting about 3° below average, so you’ll want a decent suit. Monday the 20th starts glassy with a 2 ft south swell (61), but it’s so small it’s barely surfable. That glassy moment is a tease, but the waves just aren’t there. Things stay flat and weak through Tuesday the 21st, with messy cross-onshore winds and lumpy conditions.
Now, here’s the one standout in the whole run – Wednesday the 22nd. We get a solid jump in size with a 8 ft SSW swell on the morning, and the combined energy spikes right up to 1126 – that’s proper strong. The wind is cross-off from the SW, so the reef should hold up clean. It’s a 9-second period, which is decent, but with that much size it’s going to be only for the experienced crew – beginners, stay out of the water. The afternoon holds at 7 ft from the south, a bit longer period at 10 seconds, still clean with cross-off winds. This is the best call in the whole forecast, but it’s a heavy one.
Thursday the 23rd is still worthwhile with a 6 ft SSE swell (577) and fresh offshore NW wind in the morning, plus a drop to 4 ft from the south in the afternoon with moderate offshore breeze. The waves are clean, quality enough to get a few, but nothing compared to Wednesday’s punch.
From Friday the 24th onward, it’s pretty much back to small weak junk. We bounce around 2 ft to 5 ft for the rest of July, with poor conditions, cross-shore winds, and choppy seas most days. The 29th shows a 5 ft SSW swell (194) with light wind and clean conditions, but it’s still ordinary and short period. Into the first days of August, it’s tiny again – 2 ft to 2 ft, with weak energy (32-102) and light cross or onshore breezes. Nothing worth paddling for.
So here’s the summary: The whole run is a long stretch of meh, minus that heavy Wednesday the 22nd. If you’re an experienced surfer hungry for some power, that’s your one shot. Everyone else, keep your gear in the car and watch for forecasts to change – it tends not to stay poor for long around here.
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.
