The Lowdown
Alright folks, Rusty here. Let’s have a look at what Horseneck Beach is serving up over the next couple of weeks. Gotta be upfront – it’s a rough patch. There’s a long stretch of flatness, so you'll need to dig deep for patience.
Right off the bat, from Friday the 28th of August through the first week of September, it’s basically nothing. Swell is tiny, maxing out around 2 ft, and the wind is mostly side or onshore, leaving the water a choppy mess. Wave energy is weak, sitting between 30 and 54 on the combined swell energy scale. Not worth paddling for. There’s a cleaner moment on the morning of Saturday the 29th with a light offshore wind from the N, but the swell is only 2 ft and short-period at 7 seconds. Barely a wave.
We hit a real dead zone from September 1st through the 6th. Swell drops to almost nothing – 0.3 ft to 2 ft. Wind stays messy or onshore, and the energy numbers are in the single digits or low teens for most of it. On the 6th of September, there’s a long-period swell of 12 seconds, but it’s only 1 ft high with an energy of just 29 – just a rumor of a wave.
Things perk up a touch in the second week. On Monday the 7th of September, we finally get a decent window. The morning is nearly glassy with a light NNE breeze at 3 mph, and the swell climbs to 3 ft from the SW with a 5-second period. The combined energy hits 55 – still modest but it’s clean. That afternoon the swell pushes to 4 ft, though it gets a bit of a cross-onshore bump. Not great, but it’s the best look so far.
Come Saturday the 12th of September, we see more consistent size. Swell holds at a steady 3 ft from the SSW with a period of 7 to 8 seconds. The combined energy finally reaches triple digits at 107, and the morning has a light breeze from the E. It’s a cross-onshore, so not perfect, but it’s rideable. The water temperature has been about 72°F – a touch warmer than normal for the time of year, so that’s a nice bonus.
For the beginners, anything over 5 ft can get tricky, but that’s not a worry here – it stays small. The real problem is quality. The swell is short-period and wind-affected, with a lot of chop on the surface. Horseneck is a sandbar break that’s fairly exposed, and the crowd can show up sometimes, but with conditions this average, you probably won’t be fighting for waves.
If you’re looking for the best, aim for Monday the 7th morning and Saturday the 12th morning. They’re not classics, just the least bad of the bunch. The rest is a waiting game. It doesn’t stay flat forever around here, so keep your gear ready.
Stay patient, stay wet.

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.
