The Lowdown
Alright folks, Rusty here with a look at what Sandy Beach has in store for us. Let me tell you, it's a tough stretch ahead, so don't be getting your hopes up for any quick sessions.
We've got a long, dry spell to start. From now, right through until mid-August, it's pretty much a write-off. Every single day through to the 16th of August is flagged as poor surf conditions. That's a solid two-week gap of nothing worth paddling out for. The wind is a constant problem, mostly a stiff cross-shore or cross-onshore breeze from the ENE at 18 to 25 mph, just chopping everything up. We do see some longer period energy pop up around the 12th and 13th of August, with a 15 to 18 second period from the S, but that's pushing a combined energy around the 800-900 mark (moderate) and it's still arriving with that messy wind. It's just not coming together.
Finally, there's a flicker of hope on Monday, the 17th of August. The morning shows a solid 10 ft ENE swell, with a combined energy reading of 1348 (strong), but the model is telling us the swell is predicted to be too big for this break. The wind does ease up a bit to a gentle cross-shore from the NE at 12 mph, but that size is just too much. The afternoon drops to 8 ft and the wind gets lighter, but the forecast is still marginal. It's a classic case of a big, messy swell hitting an exposed beach and reef with a side wind.
Honestly, the whole setup looks more interesting for kite surfing than paddle surfing through this entire period, given the persistent wind and average wave quality. Keep your board waxed and wait for a better window. The forecasts can always change, but for now, this is a tough one.
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.
