The Lowdown
Alright, let’s get into it. Honestly, I’ve gotta be straight with you – the next couple of weeks look pretty flat for Hapuna. There’s nothing on offer that I’d call a standout, but let’s walk through it.
We start off on Tuesday, July 21, with hardly a bump. A tiny 0.7 ft swell from the SSW, around 12 seconds, but a cross-on wind from the WNW is just making it messy. The combined energy is weak (23). It’s poor. Not worth paddling out.
Wednesday the 22nd through Friday the 24th sees that same tiny 0.7 ft SSW swell, but the wind swings to a light cross-offshore from the NNE, which cleans things right up. The period stretches out a bit, even hitting 24 seconds on Wednesday morning, which is a very long period groundswell. That’s a nice sign for energy, but for a wave that small, that long period just means long lulls and barely a ripple. The combined energy is still weak (55 on the best morning). The water temp is about average for the time of year, so no worries there.
Then we hit a big dry spell. From Saturday, July 25, right through to Tuesday, July 28, the swell flatlines. Zero feet of swell. Nothing. A gap of four days with no surf at all.
We get a tiny pulse back on Wednesday, July 29, with a 1.0 ft SW swell at 9 seconds in the afternoon, but the wind is cross-shore, making it choppy. That’s poor.
The pattern continues through the end of July and into August. A few glimpses of 1.0 ft to 1 ft SW swells, but the wind is often cross-on or cross, and the wave energy is laughable – mostly under 50. On Saturday, August 1, there’s a brief moment with a 1 ft SW swell, 14 seconds, and a clean cross-offshore breeze in the afternoon. Combined energy is still weak (47). It’s a surfable crumb, but nothing to get excited about.
Sunday, August 2, offers a similar story: 1.0 ft SW swell, 13 seconds, and glassy conditions in the afternoon. That’s probably the best window in the whole outlook, but it’s still tiny. Combined energy is weak (27).
After that, we’re back to flat from Monday, August 3, into the next week.
So, the bottom line: there’s no real standout here. The best bet is the glassy, clean conditions on Sunday, August 2, with that 1.0 ft SW groundswell, but it’s for loggers only. For most of us, it’s a time to wax the boards and wait.

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.
