The Lowdown
G’day, it’s Rusty here.
Honestly, the next couple of weeks are a bit of a flat spell for Horseneck Beach. We’ve got a long stretch of poor surf conditions ahead, so don’t get too worked up just yet. I’m not seeing anything that’s going to have you scrambling for your board. The water temp is sitting around 72°, which is about normal for this time of year, so at least it won’t be a shock when you get in.
The outlook starts off pretty grim. Friday the 21st has a weak 3ft ENE windswell with a short 4-second period, and a moderate cross-off breeze. It’s clean, but the combined energy is a paltry 26 – just not enough to push you around. Saturday the 22nd drops off even more, down to 1ft and then 0.7ft with light winds, but the energy is almost non-existent. You’re looking at more of a lake than a surfable ocean.
We go through Sunday and Monday with tiny, short-period swells, all under 3ft, and the winds are cross or cross-on. The energy is weak, in the single digits to the 70s. It’s not worth the paddle. The first real sign of life shows up late on Tuesday the 28th. Swell bumps to 4ft from the S with a 8-second period, and the energy jumps to 177 – that’s the first time we see a moderate value. Still, the cross-on wind from the SW chops it all up, so it’s not going to be pretty.
Wednesday morning the 1st of September sees the biggest swell of the whole window – 5ft from the SSW with a 6-second period. The energy is up at 144, but the wind is cross-on from the E, which is going to make it messy. It’s a sandbar, so it might get a bit dumpy and quick. It’s not great, and honestly, it might be more interesting for the kite surfers than us paddle surfers.
After that, it just fades away again. The swells back off to under 3ft for the rest of the run, with weak energy readings in the 6 to 90 range. The winds stay onshore or cross-onshore, and the waves are short-period windswell. A glassy moment on Thursday the 3rd with a 1ft SSW swell and light winds might give you a clean knee-high ripple, but that’s about it for quality.
So, the long and short of it: there are no standout days here. The best of a bad bunch is probably that Wednesday the 1st, but with the onshore wind, it’s not going to be worth the drive for most. If you’re desperate, keep an eye on the later forecasts, but a blank run like this is pretty normal for the area. The beach is fairly consistent at picking up swell, so it won’t stay this poor forever. Stay patient.
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.
