Alright, Rusty here. Let’s talk about Sandy Beach for the next couple of weeks.
Right off the bat, the water temp is 79°, which is right about normal for this time of year. No big surprises there.
But the waves? Man, it’s a tough outlook. We’ve got a full 16-day stretch with absolutely nothing good to surf. Not one decent session in sight.
Starting Thursday, July 2nd, through Friday afternoon, July 3rd, we’re looking at 5ft to 5ft swell from the ENE, with a short, weak period of 8 seconds. The wind is a fresh cross-shore breeze at 22 mph out of the NE, making for lumpy, chopped-up conditions. Energy is moderate, sitting between 434 and 558. Just poor surf.
Saturday, July 4th, stays lumpy in the morning with 6ft ENE swell and 22 mph cross-shore winds. Energy bumps up to 890. The afternoon tries to switch it up – the swell drops to 2ft but it’s a long-period 20-second groundswell from the S, with energy at 918. The problem? The wind stays fresh and cross-shore, so that long-period energy gets all messed up. Long period like that is best at points and reefs, but Sandy Beach is a beach and reef setup, and with cross wind, it’s not going to be clean.
Sunday, July 5th, gets worse. Wind cranks up to a strong 25 mph cross-onshore from the ENE in the morning, making it strong and messy. Swell is just 3ft from the SSW with an 18-second period. Energy is still high at 939, but the wind is the enemy here.
From Monday, July 6th, all the way through to Friday, July 10th, it’s the same story on repeat. Swell bouncing between 5ft and 7ft from the ENE, period never getting above 8 seconds, and wind is always a fresh to strong cross-shore breeze at 22-25 mph. Energy runs from 311 up to 851, but every single report says “poor surf conditions.” This is a long, dead run.
The second week doesn’t turn it around. From Saturday, July 11th, to Friday, July 17th, it’s more of the same. Mostly 5ft to 6ft ENE swell, short period, and constant cross-shore or cross-onshore winds. There’s a little pulse of 3ft SSW swell on Monday, July 13th, with a 15-second period, and again on Wednesday, July 15th, with an 18-second period. But again, the wind stays fresh and cross-shore, so those south swells get torn up.
Given that Sandy Beach is a beach and reef setup, and the wind is never offshore (the ideal direction is from the NW, which doesn’t show up at all), this whole window is a washout for paddle surfing. With those strong cross-shore winds and solid 5ft to 7ft swell, this setup honestly looks more interesting for kite surfing.
There are zero recommendations here. Not a single session with clean conditions. It’s a long blank run, and for this spot, that can happen. Forecasts can change, but right now, leave the board at home.
Rusty.

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.
Sandy's Beach is 15 km (9 miles) from the city of Kailua. If you plan a vacation in Oahu, look for hotels and other accommodation in Kailua. Kailua has rooms for a wide range of budgets as well as car hire and transport links.
