The Lowdown

Alright, Rusty here. Let's talk about this stretch of coast.

The next 16 days start off rough. Friday, July 31st is a total loss: 31 mph westerlies, 10-11 ft of sloppy slop, and the combined swell energy is massive (1387-2885), but it's all just wind-chop. Don't even think about it. We get a few days of nothing.

The first real nod is Saturday morning, August 1st. Wharariki Beach is the only game in town. We've got a 7 ft swell from the west, with a 13-second period – that's real groundswell energy (1662 combined energy). The wind is 12 mph ESE, cross-offshore, so it'll be clean. It's a bit big for beginners, but for intermediates, it's a solid call. The morning is the pick; the afternoon drops to 5 ft and goes cross-shore, so it'll get messy.

Sunday the 2nd is a big drop: 3 ft in the morning with a light southerly offshore breeze – glassy, clean, but tiny. Combined energy is only 211, so it's a longboard morning. The afternoon shrinks to 2 ft, not worth it.

Monday the 3rd is a cruel tease. A big 8-8 ft swell from the west, with a very long 19-second period, and the combined energy hits 4052. But the wind is screaming 31-34 mph WSW near gale, cross-offshore. It'll be clean, but it's a washing machine – only for the insane or the kite crew. The power is there, but it's howling.

Tuesday the 4th, we get a 5 ft swell from the west, 16-second period, moderate energy (1120), but the wind is a cross-shore 9 mph from the ENE. It's marginal, but you could find a corner. The afternoon is a messy cross-onshore, so hit it early.

Wednesday the 5th is the real gem. The morning is a tiny 3 ft, but the afternoon… magic. Wharariki Beach on Wednesday afternoon is glassy – zero wind, a clean 3 ft swell from the west with a 13-second period (264 energy). It's small, but it will be absolutely perfect, peeling lines. That's the session to circle.

Thursday the 6th brings a 8 ft NNW swell (8-second period – short period windswell) with a 16 mph ESE cross-offshore breeze. Combined energy is 709. It'll be clean and punchy, but that short period means it'll be a bit fat. Good for a quick hit. The afternoon drops to 6 ft and goes cross-shore.

Then we hit a long, dry spell. From Friday the 7th through to the end of the forecast, it's a grim run of tiny swell (1.0 ft to 4 ft) and howling SE to ESE winds (28-34 mph) that are cross-offshore but so strong it's just unpleasant. The combined energy is mostly under 200, and the big days like the 14th and 15th of August have a 22-second period groundswell, but the wind is a near gale, so it's just a blown-out mess. That's a solid 8 days of no good.

So, the best on offer: Saturday morning, August 1st for a solid, clean 7 ft west swell. And the absolute standout is Wednesday afternoon, August 5th – glassy, 3 ft, perfect conditions. Mark the calendar.

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.
