The Lowdown
Alright, Rusty here. Let’s get into it.
So, for the next couple of weeks, the surf is pretty slim. We’ve got a small window of rideable waves right at the start, but don’t get too excited – it’s not gonna last. After that, we’re looking at a long, dry spell with hardly anything worth paddling out for.
The best of the bunch is Hapuna (sandbar). The water temp is sitting about average for this time of year, so no wetsuit worries there.
Wednesday, July 15th is your best bet. The morning has some cross-on wind, but by the afternoon, it goes glassy. That’s a major positive. We’re looking at a small but clean 3ft swell from the west, with a very long period of 15 to 16 seconds. That’s proper groundswell energy, and with that long period, it’ll be better shaped and have longer lulls between sets, making it easier to get out the back. The combined energy is moderate (351). It’s not big, but it’s clean. Crowds are possible here sometimes.
Thursday, July 16th offers a similar story – afternoon glass again with 3ft west swell and a 15-second period. Clean and surfable.
After that, it drops off fast. By Friday afternoon, the swell is fading to 2ft, and from Saturday, July 18th onwards, we’re looking at a solid week and a half of tiny to flat conditions. The combined energy dips into the low double digits and single digits. It’s a real bummer.
Honestly, if you’re keen, get it done on Wednesday or Thursday afternoon. After that, it’s a long wait until the end of the month, and even then, the 30th of July only shows a small 1ft west swell with poor conditions. Not much to write home about.
Rusty.

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.
