Alright folks, Rusty here. Let's look ahead at what Wharariki Beach (Wairaiki-Beach) has cookin' for us over the next couple of weeks. We're starting with a bit of a slow patch, but there's some real promise later on.

Right now, the surf is pretty ordinary. Sunday the 12th kicks things off with a tiny, wobbly 3ft from the west, but that cross-on breeze is messin' it up. The water temp is 58°, which is pretty much what you'd expect for this time of year. We've got a few days of messy, blown-out conditions ahead. The swell sticks around but the wind is just too strong for decent waves until... well, things get interesting on Wednesday the 15th.

That morning, we see a jump in size to 8ft from the west, and the period stretches out to a solid 16 seconds. That's a proper groundswell with some serious grunt – the combined energy is a massive 2777! The problem is, it's cross-shore and a bit lumpy, so it won't be perfect, but there's plenty of power there.

The real standout is Thursday the 16th. The swell drops a little to 6ft in the morning and 5ft in the afternoon, but it's still a long-period west swell (15 seconds). The wind goes light and cross-offshore, making for some clean face. The afternoon session with that 6 mph breeze and 1119 energy is the pick of the week. That's gonna be smooth, strong, and offer up some nice lines.

After that, the wind goes crazy again over the next couple of days, just howling. But then, hold onto your boardies for Sunday the 19th. That morning, conditions look absolutely magic. We've got a 5ft west swell with a 16-second period, combined energy of 1005, and the wind? Dead glassy. It's going to be clean, lined up, and pushing in with that long-period energy. This is the one to circle. It's a bigger day, so best for the experienced crew who can handle that power.

The following week looks a bit quieter and more inconsistent. There are some clean morning windows, like Monday the 20th and Tuesday the 21st, with clean cross-offshore breezes but smaller swell, around 3ft to 3ft. You'll get some fun ones, but nothing with the same punch as that mid-July action. The glassy afternoon on the 21st with 2ft could be a nice sneaky session for a log.

Don't get too excited about the last few days of the outlook. There's a bit of swell around, but the wind is messy or the sizes are tiny. Saturday the 25th has a weird 1ft, 21-second period swell in the afternoon – that's an oddly long period for a tiny wave, it'll be tricky to ride. For the most part, from the 22nd onwards, it's a waiting game for the next proper pulse.

So, to boil it down: the absolute standouts are the morning of Thursday the 16th and, even more so, the glassy morning of Sunday the 19th. Get on the west coast and get ready for some quality, long-period groundswell.

Rusty.

Information about the Wharariki Beach Surf forecast

The above surf forecast table for Wharariki Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Wharariki Beach can be found by selecting the local surf guide option on the grey menu. Our Wharariki Beach 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 (Wharariki Beach) 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 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. 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.
