The Lowdown
Right then, let's have a look at what's on the menu. Honestly, this is a tough stretch for Hapuna. We've got a good long window here, 16 days, but the surf itself is just not showing up. The first few days, from the 27th of July right through to the 29th, are a complete write-off. Nothing doing – flat, no swell to speak of. You'd be better off with a kayak.
Then, from Thursday the 30th of July right through to the end of the first week and into August, we start seeing tiny little pulses of swell rolling in. We're talking ankle to shin-high waves at best. The combined wave energy is weak, barely hitting three digits. On Saturday the 8th of August, the energy does climb to a moderate 117, but even then, the swell is only 2 ft from the west, so it's still small. The wind is often light and clean, mostly cross-off or even glassy at times, so the water will look nice, but there's just no power behind it. This setup is way better for a flat day paddle than a surf.
The best of a bad bunch is probably later in the run. On Saturday the 8th of August, into Sunday the 9th, we get that 2 ft west swell with glassy conditions in the afternoon. It's not going to get your heart racing, but for a longboard or a foiler, it might be the only time you can actually catch something. For anyone else, especially beginners looking for something over 5 ft, or experts looking for power, there's nothing here. The lack of any decent swell makes the whole period a real struggle.

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.
