The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking for Horseneck Beach.
Right off the bat, I gotta be straight with you: this forecast is a tough one. For the next two weeks, we’re looking at a whole lot of flat, weak, and messy conditions. There are no standout days, and honestly, for the first eleven days, from Sunday the 23rd of August right through to Wednesday the 2nd of September, the surf is pretty much a write-off. You’ll see tiny ripples and poor conditions day after day.
The only window that even gets a whisper of hope comes right at the very end of the run. On Friday the 4th of September, the afternoon shows a bit of a pulse. We’re looking at a glassy surface with a 2ft swell from the SE, period around 8 seconds. The combined energy is still weak at 93, so it’s not gonna be pumping, but that glassy wind is a rare treat. It’s surfable, just very ordinary.
The next day, Saturday the 5th of September, the wind goes offshore from the north, which cleans things up, but the swell is still small at 2ft. The energy picks up to 166 by the afternoon, which is moderate, and the period stretches to 11 seconds, so there’s a little more push. It’s still nothing to write home about, but if you’re desperate for a paddle, the morning of Saturday the 5th might be your best, cleanest shot.
By Sunday the 6th of September, we get a similar story: clean, offshore winds, 3ft swell from the south, and period at 11 seconds. The energy hits 246 (moderate), but the swell is still small. For a sandbar break like Horseneck, that longer-period groundswell can make it break a bit too straight, so don’t expect any barrels.
Overall, the pick of a very poor bunch is the weekend of the 5th and 6th of September. The conditions will be clean with offshore winds, but the swell is just too weak to get excited about. If you’re a beginner, the small size is actually in your favour, but don’t expect much more than a knee-high dribble.
It’s been a quiet stretch, but hang in there – forecasts can change.
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.
