The Lowdown
G’day, Rusty here. Looks like we’ve got a bit of a slow start and then a proper wild ride coming up for Wainui Bay Chalet. The water’s running a bit colder than normal for this time of year, sitting at 55°F.
The first real standout is Thursday the 3rd. Clear skies, light offshore NW breeze at 6 mph, and a clean 3ft swell from the SSE with a solid 13-second period. The energy’s moderate (318), and the conditions are spot-on for a wave that’s got some push. This is your best bet early on – a nice, clean, long-period groundswell that’ll offer some proper shape. Keep an eye on the crowds though, they can show up sometimes.
We’ve got a bit of a lull after that. Friday and Saturday are small and ordinary, and Sunday the 6th is barely surfable with tiny waves. Monday the 7th and Tuesday the 8th are real flat spells – glassy but no power. Wednesday the 9th kicks up a bit with 4ft but it’s onshore and messy, so no good.
Then from Thursday the 10th to Saturday the 12th, the swell picks up energy but the wave heights stay small and the winds are all over the place. Sunday the 13th gets ugly – strong SW winds and a surging swell that hits 8ft in the morning and 13ft in the arvo. The energy is massive (1837 and 5990), but it’s cross-shore and lumpy. Not for paddle surfing.
Monday the 14th is when things get wild. The swell is 20ft from the S with a 16-second period, and the combined energy is off the charts (24543 and 27337). This is huge, heavy groundswell. The wind is cross-shore, the break is exposed, and it’s way too big for anyone but the most experienced chargers. If you’re not an expert, stay well clear. Tuesday the 15th eases a bit but still holds 7ft in the morning – still too big and messy.
Wednesday the 16th shapes up as another standout. Clear skies, a light NNW breeze at 3 mph, and a clean 3ft SSE swell with an 11-second period. The energy is moderate (268) and the conditions are clean. This is a much friendlier wave than the days before, and it’ll be a good one for a proper session.
The final few days drop off again. Thursday the 17th is glassy but tiny, and Friday the 18th has a 5ft S swell with a short 7-second period and moderate energy (372). It’s clean enough, but that short period means it’ll be a bit crumbly and less powerful.
Overall, the best two windows are Thursday the 3rd and Wednesday the 16th. Both offer clean, manageable swell with light wind. The big stuff from the 13th to the 15th is only for the elite, and the rest is mostly small or ordinary.
Rusty.
