G’day, Rusty here. I’ve gotta be straight with you – the outlook for the next 16 days is a real struggle. There’s just not a single session that’s worth paddling out for. The only spot on the radar is Fortress, a reef break, but it’s a total non-starter for the whole period.
Right now, starting Friday the 10th of July, we’ve got tiny waves at Fortress, only 1 ft to 2 ft, with a bit of a south-east or south swell. The wind is mostly light and variable, but the energy is pathetic – the combined swell energy is sitting at a weak 42 early on Friday, dropping to 34 by the afternoon. The water temp is 65°, which is a chilly 5° colder than usual for this time of year, so you’ll feel that bite. Saturday the 11th doesn’t get any better – still tiny, 2 ft to 2 ft, with onshore and cross-onshore winds making it choppy. The energy is still weak, 45 and 35. Sunday the 12th is more of the same: 1 ft to 2 ft, light cross-onshore wind, and energy barely cracking 40. We’re just treading water here.
The whole first week through to the 16th is a write-off. Swell heights barely reach 3 ft on the 15th, and the combined energy never gets above 85 – that’s weak. The wind is mostly cross-off or light, keeping it clean, but there’s nothing to ride. The 19th of July shows a slight bump to 4 ft, but it’s a short-period east swell of 5 seconds, and the wind is cross-onshore, so it’s choppy. Energy hits 110, but that’s still low.
Then, from the 20th of July, the swell starts to build, but it’s a mess. We see 4 ft to 5 ft by the 24th and 25th, with the combined energy climbing to 542 on the 25th afternoon – that’s strong energy. But it’s all cross-onshore and onshore winds, up to 25 to 31 mph, with heavy rain and a near gale warning. The swell direction is south or south-east, and the period is short, 7 to 8 seconds, so it’s lumpy, choppy, and messy. No good surf for paddling, honestly – this setup looks more interesting for kite surfing than paddle surfing.
There’s a long gap of over a week with no real recommendations. The whole 16-day window is a blank. Fortress is a fairly consistent spot, but it’s not showing any love here. The area just tends to go quiet like this sometimes. Keep an eye on the forecasts, because it never stays poor for long.
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.
