The Lowdown
Alright, Rusty here again, same deal, just in feet and miles. Looking at Horseneck Beach for the next couple weeks, and honestly, it’s a tough stretch. We’ve got a big dead period right at the start. From now all the way through to the 20th of September, there’s nothing worth paddling for. The swell is tiny, the periods are short, and the wind is mostly junk. The water temp is about 70°, which is a touch warmer than usual for this time of year, so at least it’s comfortable while you stare at flat water.
The first real chance comes on Sunday, the 20th of September. We get a little bump of about 3 ft from the SSW with a short 6-second period. The energy is low, but the wind is from the NNE at 15 mph, giving us clean conditions. It’s small and weak, but for a beginner on a sandbar, it’s the best we’ve seen in days.
A few days later, on the 23rd of September, the swell picks up to about 4 ft from the ESE, still with a short period. The energy is still low, but the problem is the onshore wind from the SSE at 12 mph. That’s going to chop it up. At a beach break with that wind and short period, this is looking more like a day for the kite surfers.
On the 24th, the period stretches to 10 seconds on a 3 ft SSE swell. The energy is moderate, but the wind is blowing hard from the SSW at 18 mph, making it lumpy and cross-onshore. Not pretty.
Nothing in this 16-day window is a true standout. The biggest swell day is the 23rd, but it’s messy. The cleanest days are the 20th and the 27th of September, when the wind goes offshore, but the swell is tiny. On the 27th, we’ve got about 1 ft of S swell with a 9-second period and a light offshore breeze. It’ll be glassy, but knee-high. If you just want to get wet on a longboard, that’s your moment.
Otherwise, it’s a lot of waiting. The second week stays small and weak. Don’t get your hopes up too high, but forecasts can change. For now, it’s a quiet spell.
Rusty.

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.
