The Lowdown
Alright, folks, Rusty here. Let’s take a look at what Horseneck Beach has in store for us over the next couple of weeks. I gotta be straight with you – it’s a tough stretch. There’s nothing that’s going to get the heart pumping, but there are a few windows where you might get a little slide if you’re really keen.
The whole 16-day run is plagued by tiny, weak swell. We’re talking about knee-high dribblers at best for most of it. The wave energy is consistently low, often in the two-digit numbers, which is a clear sign this isn't a time for big plans. The water’s sitting at around 70°F, which is a touch warmer than normal for this time of year at Horseneck, so at least you won’t be freezing while you’re waiting.
The first real glimmer, such as it is, shows up on Sunday the 13th. The morning is a complete write-off with heavy rain and a strong onshore wind. But the afternoon swings around. We get an offshore breeze from the NW at 9 mph, cleaning up a tiny 3 ft of S swell. It’s still weak, with the combined energy barely registering (48), but clean waves are clean waves. For a beginner-friendly sandbar like this, that’s about as good as it gets in this forecast.
After that, we hit a massive lull. From Monday the 14th all the way through to the end of the week, it’s flat. Swell heights drop below 0.7 ft, and the energy falls into single digits. There’s a moment on the 16th and 17th where the wind goes glassy, but there’s simply no water moving to surf.
Things try to pick up again around Friday the 18th, but the wind is onshore and the period is a terrible 3-4 seconds – just wind slop. We get another brief window on Saturday the 19th afternoon, with a clean cross-off breeze, but again it’s only 2 ft.
Moving into the second week, we see a couple of mornings on the 23rd and 25th of September that flirt with a bit more size. On the 25th, we see the highest combined energy of the whole period at 96, with 2 ft swell from the SE. The period stretches out to 10-11 seconds, which is a bit more promising for shape. The catch? It’s forecast with a stiff 19 mph NE wind, which puts it in the cross-off zone. It’s clean, but that wind will be howling. It’s a long-range pick, so don’t get your hopes up too high, but it’s the only real standout for a potential surf in the second week.
Honestly, for most of this stretch, the conditions are so small and weak that it’s going to be more appealing for a kite session than a paddle session, especially on those lumpy, onshore days.
Stay patient. It won’t stay this flat forever.
Rusty.

Information about the Horseneck Beach Surf forecast
The above surf forecast table for Horseneck Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Horseneck Beach can be found by selecting the local surf guide option on the grey menu. Our Horseneck Beach 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 (Horseneck Beach) 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 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.
