The Lowdown
Alright, folks, Rusty here. Let’s break down this Big Island stretch. It’s gonna be a real test of patience.
The whole 16-day window is pretty grim. There’s a big, quiet gap at the start before we see anything worth a paddle. The water temp is about average for this time of year, nothing special.
The first real chance is on Sunday, August 9th at Honolii Beach Park. This river-mouth spot is a wildcard. The swell is 6 ft from the E, but with a short 8-second period, it’s gonna be bumpy and weak. The wind is a cross-shore from the ESE at 9 mph, which is better than onshore but still creates some chop. The energy is moderate (450), but the conditions are still only marginal. It’s a beginner spot, but that 6 ft is a bit much for total newbies. It “rarely breaks,” so seeing it active is notable.
The pattern doesn’t improve. A few days of small, messy NE windswell follow, with the wind mostly onshore or cross-onshore. Waves are mostly 5 ft to 6 ft, but the quality is poor. The wind is a constant 9 mph from the NE or ENE, chopping everything up.
The only real standout is around Saturday, August 16th. The swell builds to 7 ft from the ENE, with a period stretching to 9 seconds. That’s a little better, but still short. The wind is cross-onshore from the ENE at 9 mph, which is only okay. The combined energy is a strong 673, so there’s power. But the surf forecast is still only marginal. This size is for experienced surfers only; it’s too big for beginners.
There’s another late pulse on Saturday, August 22nd. The swell is back to 7 ft from the E with an 8-second period, and the combined energy jumps to 967. The wind is a light cross-onshore from the E at 6 mph. It’s still a marginal call, but that’s the most energy we see in the whole period. It’s promising, but it’s a long way out, so treat it as a “maybe.”
Overall, it’s a lean run. The first real swell is a week away. If you’ve got a kite, the bigger, windier days might be more fun. For the rest of us, keep an eye on that 22nd.
Rusty.
