The Lowdown
Alright, let's get into it. Look, I’ll be straight with you. For Horseneck Beach, this 16-day run is pretty grim. We’ve got a long, frustrating gap with nothing worth paddling out for. From now right through to around the 25th of August, it’s flat to tiny, onshore junk. The first sign of any real life doesn't show up until Tuesday the 25th, and even then, it's more of a glimmer than a proper swell.
We start off with a bit of weak, short-period swell from the south on the 17th, but it's messy with onshore winds, so that’s a no-go. The next few days are just fading, tiny waves and a lot of wind chop. There’s a brief window on the morning of Tuesday the 18th with a light offshore from the north, giving us some clean 3 ft waves, but the swell is near flat and weak with combined energy of only 64. It won't hold, and the afternoon goes glassy but drops to 2 ft. That's about it for the first week, honestly.
After that, it's a dead zone. From the 19th through to the 24th, we're looking at swell under 2 ft, with a lot of cross-onshore wind and combined energy dropping into the single digits. Barely a ripple. It’s a dry spell for sure.
Now, let's talk about the one and only standout in this whole outlook. It's not perfect, but it's the best we've got. On Wednesday the 26th, we see a bump in energy. The morning of the 26th brings a 4 ft swell from the SSW (which is reasonably close to the optimum SE direction for the spot), with a period of 8 seconds, and combined energy hitting 253. It’s moderate energy but actually has some push. The winds are light and cross-shore from the ENE, keeping the surface reasonably clean with just small wind ripples. This is your window if you're desperate for a surf. It’s still a beach break, so it’ll be a bit sectiony, but there will be some rideable waves for a beginner. The afternoon stays clean with a 4 ft swell from the same direction with energy of 208. It's not pumping, but it's the most surfable we're going to see.
The 27th drops off hard, with a long-period (12 second) 1 ft swell, but it's crossed-up with onshore wind, so that's a write-off. The 28th has some cleaner cross-off winds from the NE and a 12-second period swell, but it's only 2 ft to 2 ft. Again, very small water, but the wind is better. The water temp on the 17th was 73°F, which is just a touch warmer than normal for this time of year, nothing crazy.
So, honestly? If you're a beginner who just wants to get wet and catch a couple of foam balls, Wednesday the 26th morning is your best bet. For everyone else, this is a solid two weeks to do something else. The forecasts could change, but right now, it’s a long wait for a tiny window.

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.
