The Lowdown
Alright, this is a tough one to call. Let’s be straight with you: Horseneck Beach (Horseneck-Beach) is looking like a flat spell for the next couple of weeks. The water temp is sitting at 71°, which is about average for this time of year, so no surprises there.
The whole 16-day window is basically a write-off for surf. The combined swell energy stays weak, mostly under 100 (23, 29, 6, etc.), with a tiny bump into the moderate range on August 28th morning hitting 225, but even then the waves are messy and the wind is cross-shore fresh. The best you’ll see is maybe 4 ft on August 28th afternoon, but it’s coming from SSW at 8 seconds, cross-onshore, and choppy. That’s not surfable for anyone but maybe a kite surfer if the wind holds.
There are a few cleaner moments—like Thursday afternoon August 20th with light offshore wind, or Sunday morning August 23rd with NNW offshore—but the swell is tiny, just 0.7 ft to 1 ft. Not enough to get excited about. The few glassy moments (Tuesday morning August 25th) are also flat as a pancake.
This is a long stretch of no surf. If you’re desperate, the best chance of something rideable is maybe August 27th afternoon through August 28th morning, but it’s going to be blown out and lumpy, with that 3 ft to 4 ft S-SSW swell. For expert riders only, and even then it’s a grind.
Honestly, the forecast is poor across the board. No standouts. No real recommendations. Sometimes it’s like this around here. Give it a week or two—things can change.

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.
