The Lowdown

Alright, let’s get into it. We’ve got a bit of a slow start here at Wainui Bay Chalet, but there are some solid windows coming if you’re patient.

Right now, the water temp is sitting at 56°, which is about 2° cooler than usual for this time of year – nothing too wild, just a touch on the fresh side, so don’t forget the booties if you’re heading out early.

The first real sniff of anything decent doesn’t show up until Sunday the 13th. Saturday the 12th is pretty much a write-off with messy cross-onshore winds, but Sunday morning is where it’s at. We’ve got a clean 6 ft swell from the SSE with a beautiful 15-second period – that’s proper groundswell energy, and the combined energy is sitting at 1350 (moderate to strong). The wind is cross-off from the west, light at 9 mph. This is the standout of the whole run if you’ve got the experience – it’s too big for beginners at over 5 ft. The crowd factor? It can get busy here sometimes, so get in early. This long-period swell will work best here since Wainui Bay Chalet is exposed and can handle it, but just know with that kind of period, it might bowl a bit too fast at the beach. Sunday afternoon gets chopped by a southerly, so stick to the morning.

Monday the 14th morning is still very good, though smaller at 5 ft from the SSE with a 12-second period, combined energy of 636 (moderate). Light cross-off breeze from the north keeps it clean. Good for intermediates.

Then we hit a flat spell. Tuesday the 15th through Thursday the 17th are small or junky – waves under 3 ft, weak energy, or poor winds. Not worth paddling out for.

Friday the 18th is a complete no-go: strong southerly winds up to 22 mph and tiny waves. Leave the board at home.

Now here’s the next real standout: Saturday the 19th morning. We’re looking at a clean 4 ft SSE groundswell with a very long 19-second period, combined energy of 1260 (strong). The wind is light cross-off from the west. This is a ripper for experienced surfers – the period is so long it’ll bring pure, powerful lines, perfect for a point or reef setup. Again, it might be a bit straight for a beach break, but Wainui Bay Chalet can handle it. Crowds are a possibility. Sunday the 20th morning is also good – 4 ft SSE at 14 seconds, clean offshore wind from the WNW. A solid intermediate day.

Tuesday the 22nd morning brings a punchy 6 ft SSW swell, but the period is short at 8 seconds. Combined energy is 697 (moderate). Offshore wind from the NW keeps it clean, but that short period means it’ll be a bit walled and weak. Worth a look if you’re desperate.

From the 24th onwards, things get big. Thursday the 24th morning has a 7 ft SSW swell, and Friday the 25th morning has a 8 ft SSE swell with a 14-second period – that’s expert-only territory, over 8 ft on the Friday morning? Actually it’s 8 ft, so still within expert range, but the Saturday the 26th morning is a proper 6 ft SSE at 12 seconds with light offshore wind. Combined energy of 1089 (strong). If you’re a competent surfer, that Saturday morning is your reward for waiting through the flat bits.

Overall, the best on offer is Sunday morning the 13th for the biggest, cleanest groundswell, and Saturday morning the 19th for that super-long period perfection. Intermediate-friendly windows are Monday the 14th morning and Sunday the 20th morning.

Stay patient, pick your mornings, and don’t bother with the afternoons unless you like chop.

Rusty.

A general guide to surfing at Wainui Bay Chalet can be found by selecting the local surf guide option on the grey menu.

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 Wainui Bay Chalet 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.
