The Lowdown
Alright, let's talk turkey. For Hapuna, looking out over the next couple of weeks, and I gotta be honest, it's a bleak stretch. There's just no real surf on the table for the foreseeable future, and you're gonna be scratching your head wondering where the ocean went.
We get a tiny little blip of something early on Tuesday the 8th. A swell shows up with a height around 7ft, but it's coming from the WSW with a period of 11 seconds. The energy reading is strong at 1186, but the winds are a mess, blowing cross-onshore, and the call is just marginal. It's not gonna be clean, and it's not gonna be organized. That afternoon, the swell drops to about 6ft, but the wind is still not our friend. This is a short, sharp little window that could get you a couple of grovelly ones, but it's nothing to get excited about.
Then the switch gets flipped off. From Wednesday the 9th through the middle of the next week, the ocean just goes flat. We're talking ankle-slappers and closeouts for days. There are some long-period pulses that show up in the data—like a 22-second blip on the 14th—but the swell height is a pathetic 0.7ft, and the energy is weak. It's like getting a whisper when you need a shout. There's a slight nudge in energy around the 15th and 16th where the reading gets back over 100, but we're still only looking at just over a foot and a half of swell, and the quality remains poor.
So, you're looking at a solid nine or ten days of nothing, from the 9th through the 18th or so. The surf quality is just a big fat zero. With conditions this poor, the lineup at Hapuna will be empty, which is fine, but there's a reason for it. The wind does go light and glassy on several afternoons, which is a tease, but there's just no wave to ride. This is a spot where the ocean has just shut down, and that's that.
If you're desperate for a paddle, that early Tuesday morning window is your only real option. But if you want a wave with some push to it, you're better off finding something else to do for the next week and a half. Keep the faith, but don't hold your breath.

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.
