Halawa Surf Forecast and Surf Report

G’day, Rusty here. Look, I’ve been staring at the charts for Halawa and I gotta be straight with you—this 16-day window is a mixed bag of frustration and a couple of flickers of hope. For a spot that’s a reef/river setup, exposed to the north-northwest but getting hammered from the east-northeast most of the time, the wind is the real villain here. The overall pattern is a whole lot of cross-shore breeze, lumpy chop, and poor surf conditions, with a few days where the stars might just align.

We kick off on Friday, 4th September, and it’s a write-off. Morning has a 7ft ENE swell at 7 seconds, but it’s cross-shore at 22 mph from the ENE—total chop, poor surf. The energy’s moderate, around 398, but it’s a mess. Afternoon doesn’t even get a sniff with a tiny 0.3ft northerly. The next few days—Saturday, Sunday, Monday—are a grind. The swell builds, peaking at 8ft from the ENE on Monday morning with a period of 13 seconds, and the energy gets strong, hitting 2230, but that cross-shore wind just won’t let up. It’s a lumpy, cross-chop nightmare. Saturday morning has a 8ft, 13-second ENE swell at 1826 energy, but it’s still cross-shore and marginal at best.

Then, right on Tuesday, 8th September, something shifts. Tuesday morning, the wind swings offshore from the SSE at 16 mph, and the swell drops to a clean 6ft from the ENE, period 10 seconds—moderate energy at 1062. That’s excellent surf for experienced surfers, and the water temp is about average for the time of year. This is the standout of the whole run. The waves will be clean, with that offshore groom, and the 10-second period is a nice, solid groundswell. Because it’s a reef/river break, the period will hold up well, giving you some nice, lined-up waves. Tuesday afternoon stays clean too, with a cross-off breeze and 5ft ENE swell, but the energy drops to 413. That morning session is the one to chase.

After Tuesday, it’s back to the same old story. Wednesday and Thursday see the swell linger around 5ft to 6ft, but the cross-shore wind returns, and the period drops to 7-8 seconds—short-period, lumpy junk. The energy falls to the 200-300 range, weak. Friday, 11th September, through to the end of the window on Saturday, 19th September, is a long, bleak run. The swell stays between 4ft and 8ft, but it’s all cross-shore at 19-22 mph, with periods of 8-10 seconds. The energy is moderate at best, and the conditions are consistently poor. Even the 1ft, 15-second NW swell on Sunday, 13th September is a glimmer that gets killed by the wind.

So, the truth is, there’s a big gap from Tuesday afternoon all the way to the end—over a week of nothing to write home about. The only real bright spot is that Tuesday morning. If you’re an experienced surfer, get on it. For beginners, the 6ft on Tuesday is a bit steep, and after that, the 8ft swells are too big and messy. The rest of the run is a washout. Keep an eye on the forecasts, though—it tends not to stay this poor for long.

Rusty.
