The Lowdown
Alright, let me tell you what’s happening with the waves around here. Rusty here.
Right now, it’s a quiet start. For the next several days, from Saturday the 8th through to about Wednesday the 12th of August, the surf is mostly small and messy. We’re talking tiny, short-period swells and winds that are just not playing ball. You’re looking at a stretch of pretty poor conditions, with the wave energy being weak to moderate – hitting values like 125 (moderate wave energy) up to around 478 (moderate wave energy) but it just doesn’t come together. The water temp is sitting at a warm 81°F which is about average for this time of year, so at least it’s pleasant to sit in.
Disappearing Sands is the only break on the cards. It’s a beginner spot, exposed to the WNW swell, but it’s inconsistent and can get crowded sometimes. For the first few days, honestly, don’t bother. There’s a gap of poor surf from Saturday through to Tuesday morning.
Things start to look a little more interesting on Thursday the 13th afternoon. We get a glassy period with a tiny 2ft swell from the NNE, but the period is a short 6 seconds. It’s surfable but very ordinary. Then, Friday the 14th afternoon is the real standout in this whole outlook. The swell jumps to a clean 7ft from the NNE with a 7-second period, and the wind goes glassy. That’s going to produce some proper, clean waves. The combined energy is strong at 442 (moderate wave energy). For a beginner spot, 7ft is getting a bit sizey, so it might be more for the better beginners or intermediates. This is your best bet by a long shot.
Saturday the 15th morning still has some size, with a 7ft NNE swell (moderate wave energy at 929) but the cross-onshore wind will mess it up a bit. After that, it all falls apart again with strong winds and zero surf through the weekend and into the next week. There’s another long gap of no-good conditions from Saturday afternoon right through to the end of the forecast.
Looking way ahead, there’s a little glimmer on Saturday the 22nd of August afternoon. Another glassy period, with a 2ft swell from the SSW, a very long 18-second period, and combined energy of 200 (moderate wave energy). That long period will make for clean, lined-up waves but it’s tiny. It’s promising but that’s two weeks away, so don’t hold your breath.
So, to sum it up: Friday the 14th afternoon is your window. Glassy, 7ft NNE swell. Get on it.
Stay frothy,
Rusty

Information about the Disappearing Sands Surf forecast
The above surf forecast table for Disappearing Sands provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Disappearing Sands can be found by selecting the local surf guide option on the grey menu. Our Disappearing Sands 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 (Disappearing Sands) 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 Disappearing Sands 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.
Disappearing Sands is 94 km (58 miles) from Hilo. If you plan a vacation in Big Island, look for hotels and other accommodation in Hilo. Hilo has rooms for a wide range of budgets as well as car hire and transport links.
