The Lowdown
Right, let’s have a look at what’s on the table. To be straight with you, the next 16 days are a tough stretch for Horseneck Beach (Horseneck-Beach). The file shows a long run of poor surf conditions, with the first real glimmer of something rideable not showing up until Sunday the 20th of September.
The opening week is basically a write-off. From the 13th through the 19th, we’re looking at tiny, weak waves—most of the time under 2ft—with short-period windswell that’s just not gonna hold up. The combined energy is mostly in the single digits or teens, barely registering. The winds are all over the place, but there’s nothing that lines up with the SE optimum direction in a meaningful way. You’d be better off staying home.
There is a gap of about six days with no real surf to speak of.
Sunday the 20th of September is the first day that pokes its head up. The morning shows a bump in swell to 4ft from the SSW, with a period of 7 seconds. The combined energy jumps to 112, which is at least moderate. That’s the biggest swell of the whole outlook. But—and it’s a big but—the wind is a light cross-onshore from the S at 10 km/h. That’s not ideal, but it’s light, so the surface won’t be completely wrecked. It’s a beginner-friendly sandbar break, so the 4ft is just about right for that crew, but it’s not exactly a standout. It’s the best of a bad bunch.
The rest of the run is more of the same. Monday the 21st gets cleaned up by a stiff NNE wind, but the swell drops back to 0.7ft. There’s a little spike in combined energy on the 27th of September up to 77, with a 3ft SSW swell, but again it’s short-period and cross-shore winds. Nothing to get excited about.
Honestly, this is a bleak forecast. Horseneck is fairly consistent as a spot, so this blank run feels unusual. The water is sitting at 71°F on the 13th, which is a touch warmer than normal for the time of year, but that’s about the only highlight. The swell direction never matches that SE optimum in a clean way, and the periods are short. If you’re desperate, the morning of the 20th is your only real shot, but keep expectations low.

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 Horseneck Beach 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.
