The Lowdown
Hey folks, Rusty here. Let’s talk about what’s on offer at Sandy Beach over the next 16 days. Straight up – it’s a long, quiet stretch. The forecast shows no good surf opportunities at all from now through to the end of July. The water’s sitting at 79°, which is bang on average for this time of year, so no surprises there. But the wind has been a problem – almost constant cross and cross-on breezes, mostly fresh to strong, with a lumpy, messy chop. The swell that does show up is either short-period junk or, when it gets longer, the wind just ruins it. The combined wave energy bounces around between weak and moderate (84 to 1628), but it never lines up with clean conditions. The break itself is fairly consistent normally, so this kind of blank run is a bit of a bummer – but it won’t stay poor forever.
Looking at the sequence: Monday 13 July afternoon starts with a weak 3ft SSW swell (15s period, 542 energy) but cross-shore wind at 19 mph gives us lumpy chop. Nothing rideable. Tuesday 14 July brings a bit more size – 5ft NE swell in the morning, but it’s short period (8s) and cross-shore again, plus rain. That pattern holds through Wednesday, Thursday, Friday – all poor. Saturday 18 July sees a jump to 6ft ENE swell, but the wind picks up to 25 mph, making it a messy, strong cross-shore situation. Honestly, that setup looks more like a kite-surfing day than a paddle session. The same goes for Sunday and Monday the following week. There’s a brief glimmer at the very end: Monday 27 July and Tuesday 28 July. The swell gets long-period (15–13s) from the east, with combined energy climbing into the 1000s, and the wind eases back to light or gentle breezes. But the waves are still marginal – questionable tide, and the wind is onshore or cross-onshore. The scores are low, so I wouldn’t get your hopes up. In short, there’s nothing worth paddling out for in the entire 16-day window. Keep an eye on the forecast – things can change. Stay tuned.

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.
