Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.

To be straight with you, this is a tough run. The whole 16-day window is looking pretty grim for Sandy Beach. We've got a persistent, strong breeze blowing from the ENE almost every day, which keeps the waves all chopped up and messy with a strong cross-shore. The swell is there, but it's a short-period, wind-driven affair, and the wind just ruins it. The combined wave energy is moderate, hitting numbers like 888, 919, and 725, but it doesn't matter when the surface is that ugly. The water temp is 80°F, which is about average for this time of year with a tiny anomaly of 0.9°F, so the water feels normal.

The entire first week, from July 6th through to July 12th, is a write-off. We're looking at swell heights from 6ft to 8ft, but it's all cross-shore, lumpy, and poor. There's no standout session, no window of clean conditions. The wind just doesn't let up. The crowds at Sandy Beach are often there, but with this quality, it'll be quiet.

The second week, from July 13th to July 21st, doesn't get any better. The swell drops a bit, but the wind stays on it. By July 16th, the swell gets all weird and mixed up, dropping to 2ft with a 17-second period from the SSW, but the wind is still cross-shore, so it's still not clean. There's a bit of a longer-period groundswell trying to sneak in around July 20th and 21st, with 3ft and 3ft swell from the east with periods of 15 to 19 seconds, giving a strong combined energy of 758 and 694. But again, the cross-shore and cross-onshore winds just chop it up.

Honestly, with this constant cross-shore breeze and the beach-and-reef setup, this stretch is looking far more interesting for kite surfing than paddle surfing. There's just no clean shoulder to be found. It's a blank run, and I'm sorry to say, there's not a single recommendation I can make. Don't give up hope, though; forecasts can change.

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.
