The Lowdown
G’day, Rusty here. Let’s be straight with you – the next 16 days at Horseneck Beach are a pretty grim stretch for surfers. Every single session in the forecast comes back as poor surf conditions, with no real energy to work with. The combined swell energy barely cracks double digits most days, and the highest reading is a paltry 68 (moderate energy) but even that is paired with messy winds. You’re looking at a long gap of flat or near-flat, choppy, wind-affected junk from now through the end of the month. There’s no standout session, no hidden gem, nothing to get excited about.
Let’s run through the week. Sunday August 16 starts with a tiny 0.7 ft SE swell, period only 6 seconds, and a light south breeze making it cross-onshore. Afternoon gets worse – 25 km/h SSW wind, same tiny swell. Monday August 17 has a bit more height at 3 ft from the SSW, but the period is a pathetic 5 seconds and it’s onshore or cross-onshore with rain. Tuesday August 18 morning offers the cleanest conditions of the whole outlook – a light NNE cross-offshore breeze and 3 ft S swell at 7 seconds, but the combined energy is only 68. It’s clean but tiny, weak, and the swell direction is from the south while Horseneck wants SE. Hardly a wave to bother with. The rest of the week is more of the same: 0.7 ft to 2 ft, periods mostly 5-7 seconds, with cross-onshore or onshore winds. Thursday August 20 has a clean cross-offshore breeze both morning and afternoon, but the swell is only 1.0 ft. You’d be better off staying home.
The second week doesn’t offer any hope. Monday August 24 morning turns glassy with a NW wind, but the swell is a pathetic 2 ft at 6 seconds. Thursday August 27 morning goes glassy again with a WS wind, and the swell jumps to 1.0 ft but with a long 12-second period, giving a combined energy of 63. That’s a groundswell – long period, but it’s tiny and the direction is SSE, not the optimum SE. Long-period swells on a beach break like Horseneck can be too straight and wonky, and this one is just too small to matter. Afternoon that day gets a little more height (2 ft) but the wind goes cross-shore. The final days from August 28 to 31 are all 0.7 ft to 2 ft, with short periods and mostly cross-onshore or onshore winds. Nothing.
Water temperature? No anomaly is given, so it’s just average for the time of year. With the swell this weak, the water temp doesn’t even matter.
Look, I hate to say it, but this is a total blank run. Horseneck Beach is a sandbar setup that’s fairly consistent, but when the swell is this small and the wind keeps screwing it up, there’s not a single ride worth paddling for. The combined energy values are all kid-stuff – most are below 50, and the highest is 68. That’s weak. For kite surfing, the afternoon onshore winds and choppy conditions might be more interesting, but for a paddle surfer? Forget it. Forecasts can change, but right now, don’t bother.
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.
