The Lowdown
Alright, I’m looking at the outlook for Hapuna over the next couple of weeks and I gotta be straight with you – it’s pretty grim. There’s a long stretch of nothing much happening, and honestly, there’s no standout session worth getting excited about. The whole 16-day window is basically a bust for decent surf.
From Wednesday the 26th of August right through to early September, the swell is tiny – we’re talking 0.7 ft to 1.0 ft from the SSW or W, with periods all over the place but mostly short. The combined energy of all swells directed here is weak, usually under 50, sometimes as low as 9 or 8. That’s just not enough to push a decent wave. The wind is mostly cross-off or light, so the surface is clean, but with no swell, it’s a lake. The water temperature is 82°F with a 2°F anomaly – a touch warmer than normal, which is nice for a paddle, but not for surfing.
There’s a gap of several days with no surf at all – the energy drops to zero on some afternoons. Even when the swell picks up a little around the 10th of September, we get a 2 ft from the WNW with a 14-second period and combined energy hitting 152 – that’s moderate energy, finally. The wind is offshore from the ENE at 25 mph, which is strong offshore and clean, but it’s near gale force on the morning and hard to paddle into. That Thursday afternoon might be the only window where the shape is okay, but it’s still small and only for the keenest.
Hapuna is a sandbar break, fairly exposed, best with swell from the west. The optimum direction is west, but the swell we get is mostly SSW or cross. The crowds are “sometimes” an issue, but with surf this small, it won’t be. The break is fairly consistent, but the swell just isn’t there.
So, bottom line: no good surf options in this 16-day window. The forecast can change, and it’s a fairly consistent area, so it won’t stay poor forever, but for now, leave the board at home.

Information about the Hapuna Surf forecast
The above surf forecast table for Hapuna provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hapuna can be found by selecting the local surf guide option on the grey menu. Our Hapuna 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 (Hapuna) 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 Hapuna 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.
Hapuna is 84 km (52 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.
