The Lowdown
Alright, Rusty here, checking out the surf on the Hilo side of the Big Island. I gotta be honest, the next couple of weeks are looking pretty tough for Honolii Beach Park. This river mouth spot is open to the north-east, and that's exactly where the wind is coming from most of the time, which just messes up the surface. We're looking at a lot of days with marginal or poor conditions, so you're gonna need to be patient.
The first real chance to paddle out is the morning of Saturday, August 3rd. There's a 5ft swell from the ENE, but it's a short period, only 8 seconds, and the wind is a light cross-onshore. It's not perfect, but it's the first thing we've got. The combined swell energy is moderate at 447.
After that, it gets real quiet. By Tuesday, August 6th, the swell drops to 3ft and the energy is only 79, so that's a real lull. We're basically waiting until the morning of Sunday, August 11th, when a new pulse of 5ft ENE swell shows up with a bit more energy (345). The wind is still cross-onshore, though, so it's not a standout.
The one session that stands out, the one that gets my attention, is the afternoon of Saturday, August 17th. The swell jumps up to 8ft from the east, with a period of 9 seconds. That's a powerful, solid wave. The combined energy is massive at 1976. Now, that's a big wave for a river mouth, so it's gonna be a heavy, moving wall of water – definitely for experienced surfers only. The downside is the wind is still a light cross-onshore, so it won't be glassy. But that's the biggest, most powerful swell we've got.
For the morning of Sunday, August 18th, we have a similar 7ft east swell (810 energy), but it's onshore wind again. The afternoon of the 17th is the one to circle on the calendar. The water temp is running about 80°F, which is normal for this time of year in Hilo, so you're in a rash guard or a shorty.
So, to sum it up, it's a quiet run with a lot of cross-onshore wind. The 17th of August is the one to try and get on, but it's a big, powerful wave.
Rusty.
