Table - best surf conditions forecast for Kawaihae Breakwater over the next 16 days.
Alright folks, Rusty here. Let’s break down what’s coming for Kawaihae Breakwater.
We’re starting off pretty slow. Sunday and Monday the 12th and 13th are tiny, with waves only about 1ft from the SW, a long 16-second period, but the energy is weak (120). The wind is offshore, so it’s clean, but the surf is just too small to get your heart racing. It’s more of a paddle than a surf.
The real window to watch is from Tuesday the 14th through to Friday the 17th. That’s when we get a nice little pulse of W swell. Wave heights build to about 3ft, still with a solid 15-16 second period, giving the waves some real shape and punch. The energy jumps into the moderate range (up to 354), and the wind turns glassy and light, with some offshore flows. This is textbook clean conditions for the break. Water temp is a warm 80°, which is right where it should be for this time of year.
Tuesday morning (14th) is the standout: 2ft W swell, glassy, and 298 energy. It’s not going to be huge, but it’ll be clean and fun. The break is fairly consistent, and crowds can pop up sometimes, so hit it early.
After Friday the 17th, the swell fades fast. The weekend drops to 1-2ft, and from the 20th onward, it’s basically flat or tiny. There’s a long stretch of poor to no surf from the 20th all the way to the 27th, with energy dropping to near zero. The 24th shows a tiny 1ft WNW blip, but it’s not enough to get excited about.
So, the best of the 16-day window is definitely Tuesday the 14th through Friday the 17th. Tuesday morning and Wednesday morning are the top picks. After that, it’s a long flat spell.
Rusty.
