The Lowdown
Alright, let’s get real about this one. The window opens, but there's barely a whisper for the first week.
No good standouts to hype here. Tuesday, August 18th morning is your first slim chance: a 3ft south swell, light offshore wind from the north, clean surface. Energy is moderate at 125 by the afternoon, but that swell is still tiny and soft at 3ft. That afternoon goes glassy, but it’s just not doing much. Water temp is about 73°, a touch warmer than normal for this time of year.
The rest of the run into the end of August stays small – mostly 1 to 2ft swell, short period, and onshore winds messing it up. A few clean pockets, like Thursday the 20th morning with a light offshore and glassy conditions, but the swell is barely 1ft. That’s a flat day, not a surf day.
From Tuesday the 25th, we see a little bump to 4ft from the south-southwest in the afternoon, energy climbing to 127, but the cross-onshore wind makes it choppy and not much fun. That kind of size with onshore wind is a kite session, not a clean paddle.
Honestly, the whole 16-day look is pretty lean. A couple of cleaner moments – Tuesday the 18th afternoon being the best on offer – but this is a quiet stretch. For the area, blank runs like this happen. It won’t stay this way forever; forecasts can shift.

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.
