Table - best surf conditions forecast for Sandy Beach over the next 16 days.


Alright, let’s get into it for Sandy Beach. Over the next couple weeks, it’s a rough stretch. Water temp is about average for the season at 79°, nothing unusual there. But the surf… it’s mostly a mess.

The whole period is hammered by a strong, steady cross-shore wind from the ENE, blowing 19 to 25 mph. That keeps the surface lumpy and choppy, and the surf quality is just poor. Most days we’re looking at short-period, weak ENE windswell around 5 ft to 7 ft, but it’s all cross-chop and no shape. Even when the odd pulse of longer-period SSW groundswell tries to sneak in around the 15th and 16th, with periods of 14 to 17 seconds, the wind is still cross or cross-on, ruining any chance of clean waves. The combined wave energy fluctuates but mostly sits in that moderate range.

Friday the 10th through Sunday the 12th – it’s just ugly. Swell around 6 ft to 7 ft from the ENE, but with that 25 mph cross-wind, it’s messy cross-chop. Honestly, this setup looks more interesting for kite surfing than paddle surfing.

From Monday the 13th to Wednesday the 15th, the wind drops a notch to 16-22 mph, but it’s still cross-shore. Swell drops to 5 ft to 6 ft ENE, with weak energy. Still poor conditions.

Thursday the 16th brings a change – a long-period SSW groundswell sneaks in, 2 ft at 16-17 seconds. But the wind is still cross or cross-on at 19-22 mph, so it’s lumpy. For a beach and reef break like Sandy Beach, that long period groundswell can be too straight, but with no clean wind, it’s a write-off.

Friday the 17th through Monday the 20th, the ENE windswell kicks back up to 5 ft to 7 ft, but the wind stays strong (22-25 mph) and cross-shore. More lumpy, poor surf. The crowd factor at Sandy Beach is “often” – but with conditions this bad, it won’t be an issue.

The tail end, from Tuesday the 22nd to Saturday the 25th, the swell drops to 2 ft to 5 ft, with the same cross-wind. There’s a fleeting pulse of long-period S and SSW swell on the 24th and 25th (2 ft to 2 ft, 16-20 seconds), but again, the wind is cross or cross-on, so it stays messy.

Plain and simple – there are no good surf options in this 16-day window. Nothing is breaking clean. Sandy Beach is fairly consistent, but with this constant cross-wind and short-period chop, it’s a blank run. It tends not to stay poor for long in this area, so keep an eye on the forecasts, but for now, leave the boards in the car.

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.
