Table - best surf conditions forecast for Hapuna over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Hapuna over the next couple of weeks.
First, the honest truth: we’re looking at a long, flat spell to kick things off. There’s not a single standout wave in the first week. From Thursday 9th July right through to the 13th, it’s all tiny mush – nothing over 1 ft and mostly with a long, weak 15-second period that just doesn’t have the grunt for this sandbar setup. The combined swell energy is barely a whisper (33 to 117), and with cross-off winds, you’d be fighting for a dribble.
The water temp is about what you’d expect for this time of year, so no surprises there.
Things start to get a little more interesting come Tuesday 14th July. The swell bumps up to 2 ft – 2 ft, with a solid 19-second period from the west. That’s a proper groundswell, and the energy jumps to 223 – 244. It’s still a small wave, but that long period will give it some shape. Winds are light, so it’ll be clean. But honestly, it’s still pretty ordinary. The real glimpse of hope comes Wednesday 15th July morning: 3 ft from the west, 16-second period, and the energy is pumping at 354. That’s a decent little pulse. By Wednesday afternoon, with a light cross-off breeze, it’s looking like the best we’ll see.
The standout of the whole 16-day window is Wednesday 15th July through to Thursday 16th July morning. Hapuna will see waist-high sets (3 ft) from the west, with a long 15-second period. The combined energy reaches 354 on Wednesday, and 320 on Thursday morning. Winds are light, so the surface will be glassy and clean. It’s a small window, but for this stretch, that’s the only time you’ll get a proper wave. The direction is a good match for the spot too.
After that, it fades fast. By Friday 17th, it’s back to 2–2 ft and dropping, and by Saturday 18th, the swell is gone again. The last week sees nothing but flat, tiny dribble. So if you’re keen, make Wednesday 15th and Thursday 16th your days. It’s not a classic, but it’s the only pulse we’ve got.
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.
