The Lowdown
Alright folks, Rusty here. Let’s keep it simple: this forecast is mostly a whole lot of nothing. The ocean’s gonna be quiet, so don’t rush to the beach.
The one and only real window we have in this entire 16-day stretch is Monday, August 17th. A small pulse of south swell shows up, and the wave energy climbs to a moderate 233, the strongest we’ll see. The early morning is a washout with a stiff W wind making things rough. But the afternoon is the time to go. A gentle offshore breeze from the NNW cleans it up nicely, and we’re looking at around 4ft of S swell. It ain't epic, but it’s the only rideable surf we’ve got in this whole period.
After that Monday, it’s over. The swell drops way down, and for the next week and a half, we see nothing but tiny, weak, and choppy days. Sure, there are moments of glass off on Tuesday morning, Aug 18th, or Sunday morning, Aug 23rd, but there’s no swell underneath it—heights around 1ft and energy readings in the low teens. It’s a proper flat spell, and it’s going to feel that way.
There’s a tiny bump of energy on the 26th, with about 4ft of SSW swell, but a cross-shore wind is going to chop it all up. Not worth the drive. The last few days are just more of the same poor stuff.
So, what’s the game plan? Monday afternoon, August 17th, at Horseneck Beach (sandbar) is your one and only shot. Otherwise, this stretch looks a whole lot more interesting for kite surfing than paddle surfing. The surf is going to be a no-go for a while.
Keep the wax dry, and wait for the next one.
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.
