Right, listen up. Rusty here. Let’s have a yarn about Sandy Beach for the next couple of weeks.
Straight up, this is a tough one. We’re looking at a solid 16-day stretch, but the honest truth is there isn’t a single damn day I’d paddle out at Sandy Beach for a proper surf. Every single session through the whole period is marked as poor surf conditions, and the wind is the main culprit. It’s stuck in a relentless cross-shore pattern, whipping in from the ENE at 19 to 25 mph for almost the entire forecast. That’s going to chop the surface to bits and keep things messy. No glassy mornings, no offshore windows.
The swell itself is a bit of a mixed bag. For the first week, we see a lot of short-period (7 to 8 second) ENE windswell running between 5 ft and 7 ft. That’s enough to get some lumps, but with that wind, it’s just bumpy, onshore junk. There is a notable brief shift on the 4th and 5th of July, where a very long-period groundswell from the S/SSW rolls in with periods of 18 to 21 seconds and the combined wave energy climbs into the high hundreds (up to 946). Even then, the ENE cross-breeze ruins it. A long period like that is typically better suited to a point or reef, but at a beach and reef setup like Sandy Beach with cross-wind, you’re not getting the good shape.
The water temperature sits at 79°F, which is bang on average for this time of year—no weird anomalies to report there.
Looking deeper into the second week, from the 10th of July onward, the swell drops off a bit, with heights mostly around 5 ft to 6 ft and the period still stuck in that short 6 to 8 second range. The wind doesn't let up, still cross-shore from the ENE at 19 to 25 mph. The energy values drop into the mid to low hundreds for many of those days, suggesting weaker surf on top of the poor conditions.
Basically, for a surfer looking for a clean wave, there’s nothing on offer here for the entire 16-day run. With that constant cross-shore wind and the mainly short-period swell, this setup honestly looks far more interesting for kite surfing than paddle surfing. You’d be better off leaving the board on the roof for this one. Forecasts can change, but right now, it’s a blank run.
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.
