The Lowdown
Right, grab a coffee, let’s have a look at Horseneck Beach over the next couple of weeks. Honestly, it’s a pretty quiet run for this sandbar setup. The water’s sitting at 73°—about a touch warmer than normal for August, so that’s a nice little bonus if you’re just having a splash, but the surf itself is a struggle.
For the first week, we’re looking at tiny, weak swell. It’s all in the 1 ft to 3 ft range, with short period stuff—mostly around 5 to 6 seconds—so no real push. The wind is a pain too, swinging cross-onshore or cross most of the time, keeping the surface lumpy and choppy. The combined energy is barely scraping double digits, mostly between 17 and 64 (weak energy), so it’s not doing much.
There’s a glimmer on Tuesday the 11th and again on Friday the 14th morning, where we get a clean, cross-off breeze (WNW). The swell’s still only 2 ft to 2 ft, but at least it’s clean and rideable for a beginner on a foamie. Saturday the 15th morning sees a proper offshore from the NNW with 2 ft at 8 seconds—clean as a whistle, but tiny. That’s probably your best bet in the first week if you’re desperate.
Now, into the second week, things get a bit more interesting. Around the 21st and 22nd of August, the combined energy jumps up to 118 and 191 (moderate energy), with a longer period of 12 seconds and swell from the S. That’s a proper groundswell. The problem? The wind is onshore or cross-onshore with rain, so it’s messy. If that wind cleans up, it could be something, but right now it’s poor surf conditions. Also, that longer period at a beach break like Horseneck can make it break a bit too straight, so it’s not ideal.
The standout, if you can call it that, is Saturday the 15th morning: glassy offshore wind, clean conditions, but only 2 ft. For a beginner spot, that’s workable. Other than that, you’re waiting on a clean window that never quite lines up with the size. The second week has a few clean moments on the 23rd, but by then the swell is dropping back to 1.0 ft–1 ft.
Crowds are sometimes an issue here, but with this lack of swell, you’ll likely have it to yourself. Honestly, there’s nothing here that’ll get the heart racing. It’s a flat spell with a few tiny clean windows. Forecasts can change, but right now, leave the board in the car.

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.
