The Lowdown
Alright, let me break it down for ya. It’s been a dry spell here at Horseneck Beach, and honestly, it’s gonna stay that way for a while. We’re looking at a long gap with hardly any surf worth paddling out for. The first real chance you’ll get is on Monday the 17th, so that’s a solid four days of pretty much nothing.
Monday the 17th – your best bet across the whole outlook. Early morning, the wind swings around to a clean offshore from the NNW at 9 mph, and the swell is a small but rideable 4 ft from the SSW. Period’s short at 7 seconds, so it’s not gonna have much grunt, but the combined swell energy is sitting at 140 (moderate) – enough to push you around. The water’s a touch warmer than normal for this time of year, at 74°. It’s not gonna be epic, but if you’re keen, that’s the window. Later that day the wind turns onshore and it’s back to ordinary.
After that, we’re into another long, flat run. From Tuesday the 18th all the way through to Friday the 28th, it’s tiny, short-period slop or onshore junk. Thursday the 20th morning has a clean 3 ft from the SSW with a slight offshore breeze, but the swell is weak (71 combined energy) and the period is a poor 6 seconds – barely surfable. Friday the 23rd has a tiny 1 ft with a clean offshore, but it’s just not enough to get excited about. Monday the 24th morning goes glassy, but still only 1.0 ft – you’d be struggling for a ride.
Bottom line: if you want a wave, point your car at Horseneck on the morning of Monday the 17th. After that, it’s a whole lot of waiting.

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.
