Alright, folks, Rusty here with the straight goods on Sandy Beach. And I’ve got to level with you—this 16-day stretch is a real grind.
The wind is howling from the ENE, a solid 25 mph the whole time, and it’s blowing straight across the waves. That’s not a nice offshore groom; it’s a messy cross-chop that’s going to ruin any chance of a clean face. The swell is coming from the same direction, ENE, which is the exact opposite of what this spot needs. Sandy Beach (Oahu) really wants that ESE swell to work its magic, and it’s just not gonna get it.
The water is sitting at 80°, which is about average for the time of year, so at least you won’t need a hood.
Let’s break it down. From Tuesday, July 7th, all the way through to Wednesday, July 15th, the surf is a no-go. You’ve got waves running from 5 ft to 8 ft, but with that constant 25 mph cross-wind, every single session is a mess. The energy is moderate, peaking around 963 on the Tuesday, but it’s all wasted energy. No standout, no clean window. For beginners, anything over 5 ft is getting serious, and a lot of this is over that, but the wind makes it unappealing for anyone.
We get a tiny tease on the afternoon of Wednesday, July 15th, with a 2 ft swell from the SSW, but it’s got a 18-second period. That’s a very long period groundswell, which is usually a dream for a reef or point, but at Sandy Beach, a beach and reef setup, it can break too straight and close out. And with that 22 mph cross-wind, it’s still a blown-out mess.
Then it’s back to the same old story until we hit July 19th and 20th. The swell jumps to 8 ft from the ENE, with energy hitting 1063 and 1118—that’s some serious power. But the wind is still there, still cross-shore at 22 mph. This is strictly for experts if it was clean, but it’s not. To be honest, with that much wind and that much chop, this setup looks more interesting for kite surfing than paddle surfing.
The best I can tell you is this: by the end of the run, on July 22nd, the wind hangs around 22 mph and the swell is a solid 7 ft to 7 ft, but it’s the same story. There is no day where the wind and swell line up. This is a total blank run, and for this spot, it’s not unusual. Keep an eye out, forecasts can shift, but right now, there’s nothing to get excited about. I wish I had better news.

Information about the Sandy Beach Surf forecast
The above surf forecast table for Sandy Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sandy Beach can be found by selecting the local surf guide option on the grey menu. Our Sandy 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 (Sandy 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 Sandy 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.
