The Lowdown
Right then, let's see what we've got for Wharariki Beach. To be honest, mate, the first week or so looks like one of those periods where you’re better off doing the chores. There's surf, but it's a bit of a battle.
The opening days, starting Thursday the 16th, have a solid amount of energy – we're talking a powerful west swell with combined energy in the thousands (2152), but it's being hammered by a fresh to strong breeze out of the west. The swell is a chunky 7ft with a long 15-second period, but that cross-off wind is going to put a lumpy, bumpy texture on it. It’s not what you'd call inviting. Friday the 17th calms down a touch with a 5ft to 5ft swell, but the wind is still a problem.
Now, you have to be patient. The real gem here is Sunday the 19th. The swell drops a little, but the wind goes absolutely glassy calm in the afternoon. For Wharariki, that is the key. That 5ft west swell (16-second period) is going to be lined up and clean. The combined energy is still a respectable 1103, and the setup looks excellent for experienced surfers. That's your standout. Get on it.
After that, we hit a real flat spell. From Monday the 20th right through to about Friday the 24th, the swell drops to under 3ft, and the energy dips into the low hundreds. It’s ordinary, small, and uninspiring. The water temp is about average for the time of year, nothing unusual.
Things start to look promising again towards the very end of the month. On Tuesday the 28th and Wednesday the 29th, a new 7ft west swell pushes in with moderate energy (1491). The wind is offshore from the southeast and light to moderate, which should clean it up nicely. It's a two-week-away call, so not a dead certainty, but it’s a proper pulse of swell. That Wednesday the 29th with a 6ft swell and a gentle breeze sounds like the better of those two days – a solid, clean option for the confident intermediate.
So, bottom line: if you're keen, your window is Sunday afternoon the 19th. Otherwise, keep an eye on that last week of July for a possible late-month paddle.

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 Wharariki Beach 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.
