The Lowdown
Alright, Rusty here. Let’s be real about this one. We’ve got a 16-day window, but it’s a tough stretch for anything decent. The only spot in the mix is Fortress, a reef break. It’s fairly consistent, but that’s about the only positive. The water temp is about average for the time of year, so nothing wild there.
The forecast starts with a gap. The first few days are a write-off. Sunday and Monday (August 2nd and 3rd) are a mess. You’re looking at small, weak swell around 2ft to 6ft from the south, with a short period of 7 seconds. The wind is a nightmare – cross-onshore and strong, hitting 25 mph on Monday morning. The combined energy is weak to moderate (82 to 389), but the conditions are just poor. Not worth a paddle.
Tuesday, August 4th, is a bit of a tease. The swell drops to 4ft from the south, period still short at 8 seconds. The energy is moderate (307). The wind shifts onshore from the east, but it’s light. The real kicker is Monday afternoon, August 3rd. The swell jumps to 8ft from the south, period 8 seconds, and the energy is strong (1052). The wind is a clean cross-offshore from the southwest at 9 mph. The surf report says "clean" and the guidance gives it a 3/10. It’s a reef break, so that long-ish period works okay. This is the only standout, but it’s a big one. At 8ft, this is expert territory, so don’t be a hero if you’re not ready. It’s your best shot, but the quality is still marginal.
After that, the rest of the first week and into the second week is flatlining. From Wednesday, August 5th, right through to Monday, August 17th, the swell is tiny, mostly under 3ft, with short periods of 4 to 7 seconds. The energy is weak (22 to 160). The wind is a mixed bag – some clean moments on the 7th and 8th with light offshore winds, but the waves are just too small to care about. The conditions are mostly "very ordinary" or "poor." The 8th of August has a morning with a light NW offshore wind and 3ft swell, but it’s a short-period S swell, so you’re just bobbing around.
Honestly, the only window is that Monday afternoon, August 3rd. If you’re an expert and you’re desperate, you might get a few. For everyone else, stay home. The gap is long and the rest of the forecast is a dud.
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.
