The Lowdown
Well, let me tell you, it’s been a bit of a frustrating stretch out at Shipwrecks (Big Island). I’ve been staring at the charts and the ocean is just... flat. We’ve got a solid 16-day window here, but for the first part of it, you're going to be weighing anchors, not paddling out.
For the first several days, through the 25th of August, the surf is going to be poor. We’re talking ankle-biters, and the wind is just making a mess of things. Most mornings have that cross-onshore breeze that chops everything up, and the afternoons aren’t much better with the cross-shore winds. The swell energy is weak, checking in anywhere from 169 to 507, with the waves struggling to hit even 4ft. It’s the kind of stuff that gets your hopes up when you look at the buoy, but then you get out there and it’s just sectiony and lumpy. Don’t bother.
The poor conditions will persist right through the end of August and into the first few days of September. There’s a bit more size around the 28th of August, with the swell pushing to 4ft, and the energy jumps up to a solid 867. That’s the first sign of something real, but the winds are still cross-shore and onshore, so it’s going to be messy. It’s a frustrating tease. The combined energy is moderate, but the quality just isn’t there. We’ll see a lot of wind chop and walls closing out. It’s not going to be much fun.
Things start to look a little more interesting on the 3rd of September. We’ve got a cleaner, longer-period swell coming in from the SSW at 5ft, with a period hitting 18 seconds. That’s proper groundswell energy, and the energy reading is up there at 849. The wind is still cross-shore, but it’s lighter. It’s still not perfect, but for a reef and point setup like Shipwrecks, that long period is what you want. It won’t be breaking too straight, but there could be some clean lines on the right tide. I’d say it’s a marginal call, but it’s the best we’ve seen all run. The water temperature is about average for this time of year, so you won't need the thickest suit.
Honestly, the real standout might just be the 4th of September. The swell drops back slightly to 5ft, but the period stays long at 18 seconds. The energy is still strong at 849. The wind, however, is the issue. It’s still cross-shore. For a spot that likes a bit of a groomed swell, it’s going to be a session of picking off the better sets, but there’s potential. It’s a far cry from the early days of the forecast. The bottom line is, we’ve got a long, flat spell ahead, with the last few days offering the only glimmer of hope. Don't get too excited about anything else.
Alright, that’s the long-range look. It’s a waiting game for now.

Information about the Shipwrecks Surf forecast
The above surf forecast table for Shipwrecks provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Shipwrecks can be found by selecting the local surf guide option on the grey menu. Our Shipwrecks 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 (Shipwrecks) 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 Shipwrecks 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.
