The Lowdown
Alright folks, Rusty here. Gotta be straight with you – it’s a tough stretch ahead for Horseneck Beach. We’re looking at a long, quiet run with hardly anything to get excited about for quite a while.
Right now, the water’s sitting at 74°, which is a touch warmer than average for this time of year, so at least the paddle won't be a shock.
The next two weeks are mostly a write-off for waves. From now through Monday, August 24th, we’ve got a massive gap of days with tiny, messy surf. You’ll see waist-high slop at best, mostly from the SW and S, but the wind is either cross, cross-on, or just too strong, making it choppy and blown out. The wave energy is weak, with most days showing combined energy values in the double digits (31, 23, 8, 11…). There’s simply no quality on offer.
There’s a glimmer of hope right at the end of the run. The best shot of the whole period is shaping up for Monday, August 24th afternoon. We’ll finally get a little pulse with a 4ft swell rolling in from the south, with a period of 8 seconds. The real kicker is the wind – it swings offshore out of the north at a light 6 mph, meaning those little waves will be clean and peeling. The combined energy jumps up to a moderate 335, showing there’s actually some push behind it. It’s still a beginner-friendly size, so it’s not going to be a world-beater, but after all the flatness, that morning and afternoon on the 24th will be the only window worth paddling out for.
Before that, the morning of the 24th has a 3ft south swell with clean offshore wind too, but the energy is much lower (93). It’s surfable, but very ordinary.
After that brief window, it looks like it’ll get messy and lumpy again with onshore winds through the 25th and 26th, with the swell bumping up to 4ft but with a short, weak 6-second period and strong cross-onshore wind – basically a choppy, closed-out mess.
So, to sum it up: save your energy. The whole 16-day window is essentially a bust except for that one clean, small day on Monday, August 24th. It’s a classic case of a long wait for a brief, clean window. That’s your shot.
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.
