The Lowdown
Alright, let’s get into it. The next 16 days at Horseneck Beach are looking pretty flat for the most part. There isn’t really any surf worth paddling out for right now, and that’s going to stretch on for a while. The first few days have tiny, weak swell, and poor wind conditions mixing things up, so there’s a long gap with no real recommendations until we get towards the end of the month.
The whole period is plagued by small, short-period swell, coming mostly from the south. Most of the time the wind is either cross or cross-onshore, which doesn’t help. The water temperature is about average at 71°F for the time of year, nothing unusual.
Let’s be real: the best on offer is around Monday the 24th of August. Through that afternoon, we get a bit of a bump – the combined swell energy climbs to 116 (moderate energy) with a swell height peaking at about 4ft from the SSW, but the period is short at 6 seconds. The wind is WSW at 22 mph, cross, so it’s going to be lumpy and rough. This is honestly more of a kiteboarding setup than a paddle session.
Another slight uptick comes around Saturday the 29th of August during the morning. Swell builds to about 3ft from the south, with a slightly longer period of 8 seconds and combined energy hitting 107 (moderate). The wind is light out of the east at 6 mph, cross-onshore, so it will be small and a bit bumpy but rideable on a bigger board.
Even with that, none of these days really stand out for clean, quality surf. If the wind had turned offshore, we’d be in for a treat, but that’s not the case. For the week leading into September, we see the same pattern – small southerly swell, short to moderate periods, and mostly subpar winds.
At Horseneck Beach, this is a pretty typical run for a quiet season. The spot can be fairly consistent, but when it goes flat, it can stay flat for a while. Keep an eye out for forecasts to change, but for now, don’t expect much.
The only window that might be worth a look is Monday the 24th afternoon for the biggest, messiest waves, and Saturday the 29th morning if you’re desperate for cleaner small surf.

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.
