The Lowdown
Alright, this is Rusty comin' to you live from the lineup.
Right off the bat, I gotta be straight with you – it’s looking pretty slow out there. We’re in for a long, quiet stretch before anything even starts to look worthwhile. The next week and a half is basically a write-off for any decent surf at Honolii Beach Park. You’ve got persistent onshore and cross-onshore winds from the ENE and NE, and the swell is small, weak, and mostly short period. The water temp is sitting at about 82°, which feels a touch warmer than normal for this time of year, so a swim is nice, but the surf is flat.
Tuesday the 25th to Monday the 31st of August is a total bust. The combined energy is barely registering (284 down to 65), with wave heights poppin' between 2ft and 5ft, but all under a brutal cross-on or onshore wind. It’s choppy, messy, and honestly not worth paddling out for.
We finally see a tiny flicker on Monday the 31st afternoon. The swell bumps up to 6ft from the ENE, and the combined energy jumps to a solid 715, but the wind is still onshore and the conditions are just marginal. The best of the bunch starts to build on Sunday the 6th of September. That morning, you’ve got a 8ft swell from the E with a period of 11 seconds. The energy is pumping hard at 1337, and the wind is a light cross-onshore from the E. This is the standout window, but it’s still not clean. It’s going to be a bit lumpy, and at 8ft, this is getting into the territory where beginners should sit it out.
Monday the 7th of September afternoon is the real pick, if you can wait. The swell settles a touch to 6ft from the E, but the period stretches out to a nice 12 seconds. The combined energy is massive at 1526. More importantly, the wind shifts to a light cross-shore from the ESE. That is going to be the cleanest the wave face gets through this whole 16-day run. For a river mouth break like Honolii, that long-period groundswell can sometimes make the wave a little straight, but with the energy we’re seeing, there will be some proper shoulders to work with.
Tuesday the 8th of September holds similar size, with 7ft to 8ft from the ENE, but the wind goes back to a light cross-onshore, so Monday afternoon is your best bet by a long shot. The rest of the second week just fades back into that marginal, onshore chop.
So there you have it. If you’ve got the patience, Monday the 7th of September afternoon is where it’s at. It’s a promise, not a guarantee from this far out, but the numbers look right. Keep your eyes on that one. For the rest? Save your wax.
Rusty.
