The Lowdown
Alright folks, Rusty here. Let's look at what's on offer at Horseneck Beach (sandbar setup). To be straight with you, the next two weeks are a bit of a bust for paddle surfing. We're looking at a long, dry spell before anything even starts to rumble. The water temp sits at a pleasant 71°F, which is about average for this time of year.
So, here’s the deal. From Wednesday 5th August right through to the morning of Tuesday 19th August, there’s just no surf to speak of. That’s fourteen days of flatness. The swell is tiny – we’re talking 1.0ft to 3ft, mostly short period windswell (5-7 seconds), and the combined wave energy is pitiful, barely hitting double digits most days (scratching around 30-80). On top of that, the prevailing southwesterly winds are pretty much always cross-on or cross-shore, so it’s choppy and messy. If you’re looking for a tan, great. For a wave? Forget it.
There are a few mornings – like Wednesday 12th, Thursday 13th, and Monday 17th – where the wind goes glassy, but there’s no swell to groom. That's all show and no go.
Now, the outlook does change on Wednesday 19th August. The swell finally begins to fill in. Mid-week we start to see some size, with the swell jumping to 4ft on Wednesday morning and building to 5ft on Thursday the 20th. The combined energy finally gets some grunt behind it, hitting 221 (moderate wave energy) by Thursday morning. But here's the heartbreaker – just as the size gets interesting, the wind is still howling from the SSW at 15-18 mph, creating a messy, cross-onshore chop. For a beach break like Horseneck with a short period (6-7 seconds), that means walls of chop, not surfable lines.
The only faint glimmer is on Thursday 20th afternoon, where we have 4ft swell from the SSW, but with that same onshore wind, it's going to be a slog. At this size and with the wind, it’s probably better suited for the kite surfers than anyone paddling. The period is too short and the wind too messy for any quality, so I wouldn’t get excited. We'll have to wait and see if the wind co-operates closer to the time, but right now, keep your board in the garage.
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.
