The Lowdown
Right, folks, let's have a look at what's cookin' for the next couple of weeks. I gotta be straight with you – it's a pretty quiet stretch for Horseneck Beach. The first week is a real struggle, with barely a ripple to speak of. You're looking at a solid week of tiny, poor surf. The combined energy is just a whisper, with values barely climbing into double digits – a measly 13 (on the 4th) being the "high" point early on, and mostly sitting between 3 and 17. It's a flat spell, no doubt about it.
The first real pulse of life shows up on Wednesday, the 9th of September, but it's not for paddling. That afternoon, the wind is howling from the SW at 22 mph, pushing up a lumpy, cross-onshore 4 ft of short-period slop. The energy finally hits 85, but it's a messy, blown-out affair. Honestly, for a beach break like this, that setup is lookin' more interesting for the kite surfers than the paddle crew.
Now, Thursday the 10th of September is the one and only standout in this entire forecast, and it's for the experts only. The morning brings a solid 8 ft swell from the SW, with a combined energy of 949 – that's a proper pulse of power. The wind is a clean cross-off from the WNW at 19 mph, which will keep the faces tidy. But listen, at that size, Horseneck is no place for a beginner. This is big, powerful stuff for experienced surfers only. The period is a short 8 seconds, so it'll be a bit dumpy and won't have that long, drawn-out wall. It's a one-shot deal, as the afternoon drops back into the doldrums.
After that, it's back to the desert. From the 11th through the 19th, it's a long, flat run with nothing but tiny waves and weak energy, mostly under 25. The water temp is sitting at 70° on the 4th, which is about average for the time of year, so you won't need a thick suit just yet.
So, to wrap it up: the first week is a write-off. Your only real chance is the morning of Thursday the 10th, if you're a strong swimmer and have the right board for a steep, punchy beach break. Otherwise, the forecasts can change, but this one's lookin' pretty grim.

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.
