The Lowdown
Alright folks, Rusty here. Let’s get straight into what’s cooking at Horseneck Beach. I’ve got the full 16-day picture, and I’ll be honest with you, it’s a bit of a mixed bag. Let's paddle out.
The first week is a struggle. A lot of wind is going to be making a mess of things. The real highlight is going to be Thursday, July 23rd, and then a late, promising window at the end of the month. Let’s break it down.
We’re looking at Horseneck Beach, a sandbar setup that’s fairly consistent. The water is a normal 70°F for the time of year, nothing weird there.
The early part of the week is a write-off. Monday the 20th and Tuesday the 21st are a solid no-go. Onshore winds are ruining any chance of a clean wave. The swell is weak and short-period, giving us a combined energy of only 41 (Monday) and 60 (Tuesday). It’s just messy.
Wednesday the 22nd sees a jump in size, with swell hitting 7 ft from the SSW, but it’s still cross-onshore and choppy. The combined energy gets up to 511, which is solid, but the wind is just killing the quality. This one is for the die-hards only, and honestly, with that wind, it’s looking more interesting for kite surfing than a proper paddle.
Now, Thursday the 23rd is your best bet in this first stretch. The morning is a bit of a gamble with the swell at 5 ft from the S (9-second period) and a light NW cross-offshore wind. The wave comment says "clean," and that’s a golden word. The combined energy is 372, which is moderate. The afternoon is even better. The wind swings to a light WSW 10 km/h cross-shore, the swell is 6 ft from the S, and the combined energy jumps to 878. That’s a solid pulse of energy, and the light wind should keep the surface glassy. This is the standout. The swell is a bit big for beginners, but for the rest of you, this is the window to be in the water. The crowd situation is “sometimes,” so you might have some company, but it’s not a circus.
After Thursday, it drops off again. Friday the 24th through to the end of the month is mostly small and weak. We’re talking knee-high dribble with combined energy barely cracking 100. The wind is onshore or cross-onshore, so it’s just a flat spell for almost a week.
Then, we get a flicker of hope on Wednesday, July 29th. The afternoon sees a 6 ft swell from the S with a 10-second period, combined energy of 850, and a W cross-offshore wind cleaning it up. The wave comment says "marginal" but it’s clean. The swell is a bit too big for beginners again.
The real sleeper might be the final Friday, July 31st. The morning is glassy. A flat 5 km/h wind from the ESE. The swell is only 3 ft from the S (8 seconds), but with that glassy surface, it’s going to be a fun, clean little session. The combined energy is only 119, so it’s not powerful, but it’s ridable. The comment says "surfable waves but very ordinary conditions," which is the most positive we’ve seen in a while. This is the second standout for the clean, mellow vibes.
The rest of the first week of August is a bust. Onshore winds and a weak, short-period swell from the SSW. The combined energy stays under 100, and the wind is just bad. It’s a classic summer flat spell.
So, to wrap it up: The best on offer is Thursday, July 23rd afternoon for the biggest, cleanest swell of the period. The second best is the glassy morning of Friday, July 31st for a small, clean session. The long gap in between is a real bummer, but that’s summer for you.
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.
