The Lowdown
Alright, let’s be straight with you. Looking at Horseneck Beach over the next couple of weeks, and it’s a slow grind. We’ve got a big chunk of nothing to start, so don't get your hopes up.
We’re looking at a real dry spell, with no surf worth paddling out for until around the 25th. That’s about a week of flatness and blown-out dribble. Water temp is where it should be for this time of year. It’s just a dead period for the beach.
If you’re itching, the 25th is your only real shot. Tuesday the 25th (Horseneck Beach) sees the first bit of rideable swell – about 4ft of southwest swell with a 7-second period. The energy is moderate, with a combined value around 111-118. The key here is the wind: it’s dead glass all day. It’s small, but it’ll be clean. The sandbar is fairly consistent, so you might snag a few. This is the pick of the litter, but it's not breaking any records.
Beyond that, it’s back to the usual summer nonsense. The 26th brings a long-period swell, but it’s tiny and chopped up by a moderate east-southeast breeze. A total non-event. The 27th is a stormy mess with onshore winds and rain. Forget it.
The 28th has some size – Friday the 28th could push 5ft in the morning and up to 7ft by the afternoon. But it’s short-period and cross-onshore. That’s a recipe for a bumpy, closed-out mess. It’s not a beginner wave at that size, and with the wind, it’s strictly for the crew who don't mind getting worked. The energy is strong, hitting 694 in the afternoon, but it will be poor quality.
The rest of the period into September drops off into small, insignificant surf. Nothing else on the horizon.
So, one day to look at, and that’s the 25th. Small but clean. The rest is a bit of a write-off. This is just what a normal summer flat spell looks like around here.

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.
