The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up at Hapuna.
Right off the bat, I gotta be straight with you: the next week or so is pretty flat. We’re looking at a dry spell with no real swell to speak of. From Sunday the 2nd right through to the end of the following week, it’s a whole lot of nothing. The few tiny bumps that show up, like a 0.7ft to 1.0ft west swell, just aren’t enough to get the heart pumping and the forecast is calling it poor surf conditions. The water temp is sitting right around 81°, which is about average for this time of year, so at least a dip will feel nice.
We finally start to see a pulse of energy around Monday the 10th. The morning brings a 2ft west swell with a period of 15 seconds, and the combined energy is moderate at 157. The wind is glassy, so it’ll be clean. This is the first real sign of life, but it’s still pretty ordinary. The best of this stretch looks like Saturday the 15th. The swell holds around 3ft from the west-northwest, with a 15-second period. The energy is strong, hitting 395. The wind goes glassy in the afternoon, which is a major positive for clean conditions. Monday the 17th also has a solid 3ft west-northwest swell with glassy conditions in the afternoon, and energy at 273. This is the standout couple of days.
Because Hapuna is a sandbar setup, those long period swells (15 seconds and up) can sometimes break a bit straight, but with the glassy or cross-off winds we’re seeing, it should still offer up some fun lines. The crowds can be an issue there sometimes, so get out early if you can.
So, the long and short of it: a long, flat wait, then a solid weekend and Monday to finish the run. The Saturday the 15th afternoon glass-off with 3ft west-northwest swell is the pick of the entire outlook.
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.
