The Lowdown
Alright, Rusty here. Let’s take a real hard look at what’s coming for the next couple of weeks.
Truth is, it’s a pretty grim stretch for Horseneck Beach. The first week and a half is basically a write-off. From Tuesday the 18th all the way through the morning of Friday the 28th, we’re looking at a long, dry gap with nothing worth paddling out for. The swell is tiny, the periods are short, and the wind is all over the place – mostly cross or onshore junk. There’s just no energy in the water (combined swell energy values stay in the single digits or low double digits during this whole period). Don’t even bother waxing the board.
Then, finally, on Friday morning the 28th, we get a little spark. A 3ft south swell with an 8-second period rolls in, and a light NNW offshore wind is blowing. That’s clean. The combined energy jumps to 138 (moderate). It’s not huge, but after all that flatness, it’s the first real chance you’ve got. The water temperature is about 71°F, which is pretty normal for this time of year, so no wetsuit drama.
The afternoon of the 28th gets a bit bigger, with 5ft south swell, but the wind swings cross-shore and the period is still short. That’s a bit lumpy and looks more interesting for the kite crew than paddle surfers.
Saturday morning the 29th is your other standout. A clean 3ft south swell with a light offshore wind from the north, and the combined energy is 103 (moderate). The water is still fine. It’s a small, clean little window that’s worth a dawny.
After that, it fades back into the doldrums. Sunday the 30th and Monday the 31st are back to tiny, weak swell with cross and onshore winds. The first few days of September look the same – small, short-period SSE swells with cross winds, just not enough to get excited about.
So, the only real standouts are Friday morning the 28th and Saturday morning the 29th. They’re not world-class, but they’re the only clean windows in a long, flat spell. Keep your expectations low, and you might just have a fun little session.
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.
