The Lowdown
Alright, folks, Rusty here.
Let's be straight with you. Looking at the next two and a half weeks, it’s going to be a real quiet stretch for paddling out at Horseneck Beach. We are looking at a long, dry spell of knee-high or ankle-high slop, with almost no rideable energy for the vast majority of the 16-day window. Honestly, you’re probably better off giving the board a rest and doing something on dry land for a while.
The water is sitting at a very warm 72°F for this time of year. That anomaly of 4°F warmer than average is a dead giveaway that summer is holding on, but it doesn't mean a thing for the surf itself.
The first few days are a total write-off. Saturday the 12th is glassy with a tiny 0.3ft swell and weak combined energy (9), but it’s just not enough to form a wave you can ride. Sunday the 13th is soggy with heavy rain and a messy, short-period windswell. Monday the 14th actually sees a clean offshore breeze from the NNW, which is exactly the right wind direction for this spot, but the swell is still just 0.3ft. It’s clean but completely flat.
That pattern of clean-but-flat continues through Wednesday the 16th. A few days show some period, like Thursday the 17th with a 13-second period, but it's only 0.3ft to 1ft of swell and the wind is onshore, so it’s basically just ripples. We are looking at a solid seven to eight days of essentially no surf.
The most interesting thing in the whole run happens way out on Wednesday the 23rd of September. The combined swell energy climbs to a moderate reading (58-74) with a 3ft swell from the SE. The wind is a strong offshore breeze from the NE, which will clean it up. The following day, Thursday the 24th, the period gets long, up to 10 seconds, but the wind turns cross-shore and messy. Friday the 25th is the true standout: the swell hits 4ft from the SSW with a moderate energy of 156. It’s actually got a bit of push to it. The wind stays offshore from the NE (18-25 mph), keeping the surface clean.
That Friday the 25th is the only real highlight. A 4ft clean, offshore wave is a solid beginner-friendly size, perfect for Horseneck's sandbar. But remember, that’s a full 13 days out, so hold your breath. The forecast is promising, but it's long-range, so don't book the day off work yet. Before that, it's pretty much a paddling pool.
Rusty, signing out.

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.
