Alright, grab a seat. I’ve had a proper look at what’s coming up for Fortress over the next couple of weeks, and I’ll be straight with you – it’s quiet. There’s no real swell to get excited about, and most days are either flat or blown out. But there are a couple of small windows where you might get a few limp waves if you’re really keen.

First up, Sunday 5 July – tiny 1 ft from the SE with a short 8‑second period and an onshore breeze. Water temp is about 68°, pretty normal for this time of year. That afternoon is a no‑go. Monday through Thursday (6‑9 July) are all poor – a mix of onshore gales, rain, and messy cross‑onshore winds. Swell gets up to 5–6 ft at one point but it’s short‑period and blown flat. Not worth paddling out.

The first faint glimmer comes on Friday 10 July morning. We’ve got 3 ft from the SSW, period 6 seconds – weak energy (74). Winds are light offshore from the NNW, so the surface will be clean. It’s still tiny and ordinary, but it’s the best of a bad bunch in the first week. Expect crowds too – Fortress often gets busy. That afternoon drops off, and the weekend (11‑12 July) is small and choppy.

Monday 13 July through to Thursday 16 July offers nothing worth chasing – small, cross‑shore winds, and lumpy conditions. Then on Friday 17 July morning we get another glimmer: 3 ft from the S, period 7 seconds, clean with a light offshore from the WSW. Combined energy is just 98 – weak. Again, ordinary but surfable. That afternoon gets messy. The rest of the period into 20 July is all poor – strong onshore winds, rain, and near‑gale conditions.

So there’s no standout swell, no pumping session. The best you’ll find are those two Friday mornings (10 & 17 July) with clean but tiny waves. If you’re a beginner and just want to get wet, those are your windows. Otherwise, it’s a pretty flat run. Forecasts can change, but right now I’d leave the boards in the car.

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.
