The Lowdown
Alright, Rusty here again. Let’s talk Horseneck Beach in terms you might be more familiar with.
For the next couple of weeks, it’s mostly flat and messy. From Sunday, August 9th through Wednesday, August 13th, there’s hardly anything going on. Wave heights are all under 3 feet, mostly under 2 feet, with a lot of cross and onshore wind messing things up. The wave energy is weak, reading between 10 and 53, so no power. The water’s a touch warmer than normal for this time of year at about 75°F, which is nice, but that’s the only highlight. The swell is short-period windswell, mostly around 6 seconds, so it’s bumpy and weak. Not worth the trip.
Here’s the one bright spot: Thursday afternoon, August 13th. The swell bumps up to about 4 feet from the SSW with a 6-second period, and the combined energy hits 111 (moderate). Plus, we get a clean cross-offshore wind from the WNW at around 12 mph. It’s still a sandbar beach break, so don’t expect perfection, but it’s the best you’ll see in this outlook. That Thursday afternoon is your best shot for a clean, small wave – mainly for more experienced folks who don’t mind a bit of work for a short ride.
From Friday the 14th through the weekend, conditions stay clean with offshore or cross-off winds, but the swell drops to under 2 feet. There’s a little bump in period to 8 seconds on the 15th, but the energy is still low (21-45). That weekend might be okay for a longboard or a soft-top if you’re really keen, but it’s not proper surf.
The entire second week, from Sunday the 16th through Monday the 24th, is basically flat or knee-high junk. Swell heights hover between 0.3 feet and 2 feet, with periods going up to 12 seconds on the 23rd, but with only 7 units of energy – that’s a glassy, flat ocean. The winds are mixed and mostly onshore or side-shore, so no real window opens up.
Bottom line: Horseneck is mostly a miss. The only session worth getting wet for is Thursday afternoon the 13th. Otherwise, save your gas.
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.
