The Lowdown
Right then, let’s have a look at what’s on offer for the next couple of weeks.
Honestly, I’m scratching my head a bit here. The outlook for Kawaihae Breakwater is pretty flat. We’ve got a long stretch of tiny, weak waves that just aren’t doing anything for us. The water is sitting at 80°F which is bang on average for this time of year, so no surprises there.
The first few days, from the 20th through to the 26th of July, are a write-off. We’re looking at waves of just 0.7ft, with combined swell energy barely registering (24). It’s just not happening. The wind is often offshore or glassy, which would be perfect if we had any swell to work with, but we don’t. It’s a real shame because the conditions are clean, but there’s simply nothing to ride.
There’s a bit of a gap with no surf at all from the afternoon of the 25th through the 29th. Then, right at the end of the month, things start to get a little less terrible. The morning of the 31st of July sees a 1ft swell from the SW with a period of 16 seconds. That’s a long period groundswell, and combined energy jumps to 66. It’s still small, but that long period means there’ll be some energy in the water. The wind is offshore from the NE at 6 mph, so it’ll be clean. It’s not a standout, just the best of a bad bunch.
The 1st of August morning is similar – 1ft SW swell, 14 seconds, with offshore winds. The energy is 81, which is the highest we see. Again, it’s surfable, but very ordinary. After that, it fades back out.
So, to be straight with you, there’s nothing here that I’d call a proper session. The only period that might get you a few small, clean waves is the morning of the 31st of July through to the morning of the 1st of August. If you’re desperate for a paddle, that’s your window. It’s a long, flat spell for this spot.
