The Lowdown
Alright, Rusty here. Gotta be straight with you. The outlook for Hapuna over the next 16 days is pretty grim. We’ve got a long stretch coming up with nothing worth paddling out for, so don’t bother checking the cams every morning.
We’re looking at a real quiet spell. From Saturday the 29th of August all the way through to Wednesday the 9th of September, it’s flat or near flat. The water temp is sitting at 81.5°, which is about average for this time of year, so nothing unusual there, but the lack of swell is the real story here.
The first hint of something rideable shows up on Thursday the 10th of September. The swell bumps up to about 2 ft from the west, with a period of 13 seconds. That’s a long period groundswell, so the energy will be drawn out and a bit straight, not ideal for the sandbar setup. The combined energy is moderate (128), and the wind is light and cross-offshore, so the surface would be clean. It’s small, but at least it’s surfable. The conditions are just ordinary, though.
Friday the 11th of September is the only real standout in this whole window. Swell holds at 1.6 ft from the west, period around 12 seconds, combined energy moderate (142). The wind goes glassy on the Friday afternoon, which is a massive positive for a break that can get clean and fun on those small days. It’s not big, but if you’re itching for a glide, that glassy window on Friday afternoon is the best we’ve got. Just keep in mind the conditions are still just surfable, not pumping. This spot can get crowded, so expect some company if you go.
After that, it pretty much fades back out into nothing through the 12th and 13th. A long, dry forecast, folks. For now, you’re probably better off doing something else.

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.
