Updates in hr min s Forecast update imminent
G’day, Rusty here. Let’s get straight into it.
Right now, there’s a big fat gap at the start. No good surf for Monday the 6th, Tuesday the 7th, or Wednesday the 8th—that’s three days of nothing worth paddling out for. The first half of the week is a write-off unless you’re after blown-out, messy, or just plain poor conditions.
Thursday the 9th kicks off the first real chance. Castlepoint - The Gap (New Zealand) on Thursday morning has 10 feet of easterly groundswell with an 11-second period. That’s a solid, powerful swell, and the energy is strong (2084 combined). The wind is a cross-offshore from the WSW, gentle breeze, clean conditions. This is for experienced surfers only—over 8 feet is expert territory. The water temp is 55°, about average for the time of year with a slight -0.5° anomaly. Thursday afternoon turns cross-onshore and choppy, so get in early.
Friday the 10th isn’t worth it—fresh, lumpy cross-shore wind with 10-foot surf. Saturday the 11th and Sunday the 12th stay marginal or poor, with wind and chop ruining any chance of clean waves. Sunday afternoon does see a drop to 3 feet from the SSW with a very long 15-second period, cross-onshore light breeze—more of a weird, slow wave. Not a standout.
The second week stays quiet. Monday the 13th morning has 3 feet SSW swell, 12-second period, cross-offshore NNW winds, clean—but tiny. Wednesday the 15th morning offers 4 feet from the ENE at 8 seconds, with a proper offshore from WNW. That’s a light, clean morning, but the waves are short period and low energy. Not a standout.
There’s nothing really worth calling a true standout in this whole 16-day outlook. The best on offer is Thursday the 9th morning for experts who can handle a big, clean groundswell at The Gap. After that, it’s a slow, quiet run with only small windows of clean surf. Crowds? The Gap is often busy, so on that Thursday morning, expect some company. It’s a fairly consistent break, so it won’t stay empty for long.
No good surf options for most of the period. But with it being a fairly consistent spot, forecasts can change.
Rusty.
