The Lowdown
G’day, I’m Rusty. Let’s talk about what’s coming up for Honolii Beach Park.
The first few days look pretty ordinary, to be honest. Tuesday the 1st through to Wednesday the 2nd, we’ve got onshore wind and rain showers, with poor surf conditions. The swell is around 6 ft to 6 ft from ENE, but with a short period of 8 seconds, it’s pretty weak and messy. Combined wave energy is moderate (407 on Tuesday morning, climbing to 578 by Wednesday morning), but it’s just not clean. No standout quality here.
Thursday the 3rd shows a slight improvement—still marginal, but the swell bumps up to 7 ft from E, period still 8 seconds, and combined energy hits 1003 (moderate). Wind is cross-onshore though, so expect a bit of chop. Not worth getting excited about yet.
The first real glimmer of hope comes Friday the 4th. The swell holds around 6 ft from ENE, but the period jumps to 14 seconds—proper groundswell. Combined energy is strong at 1408 (morning) and 1473 (afternoon). Wind is light and mainly onshore in the morning, but the afternoon has clean NE offshore breeze at 10 km/h. This is a river break, so that long-period swell (14 seconds) could be a bit straight at times, but the wave quality should be well above average. It’s still marginal on the score, but Friday morning looks like the best session of the early run.
Saturday the 5th and Sunday the 6th keep the same vibe—7 ft to 8 ft ENE swell, long periods of 13 to 14 seconds, strong energy (1475 to 1976). Saturday morning has clear skies and light NE offshore wind—that’s clean. Sunday morning also looks good with NE wind at 10 km/h. These are your standout days for the first week, but keep in mind the new moon high tide could be a factor, so check the tide charts.
Monday the 7th still has decent swell (6 ft, 11 seconds) but the wind turns cross-onshore, so it’s a step down. Tuesday the 8th drops off—swell shrinks to 5 ft, period drops to 9-10 seconds, and moderate cross-shore wind from the SE makes for a choppy mess. Wednesday the 9th is poor, with weak 5 ft swell and 7-second period.
Now, here’s a fun one for the long-range crew: Friday the 11th sees a solid 10 ft swell from E, period 9 seconds, combined energy of 2398 to 2407 (strong to very strong). That’s a fair bit of size—over 8 ft, so this is for experienced surfers only. The wind is light cross-onshore, so it won’t be perfect, but for size hunters, it’s a massive window. However, Honolii is a river mouth, and with a 9-second period, that much swell can get unruly and close out. It’s promising but keep expectations in check.
After the 11th, the surf tanks. From Saturday the 12th through to the end of the 16-day window, we’re looking at tiny swell (1.0 ft to 2 ft), short periods, and barely any energy. It’s pretty much flat. The 12th has a risk of thunderstorms and near-zero energy, so don’t bother.
The water temperature is 81°F with a 1°F anomaly—basically average for this time of year, so no worries there.
The only true standout here is Friday the 4th and Saturday the 5th, with that long-period groundswell and light offshore winds. Sunday the 6th is also clean. If you’re after big waves, Friday the 11th is the one to watch, but it’s a long way out and the winds could change. This is a very consistent break, so even when it’s poor, it doesn’t stay that way for long. Crowds are often here, so expect company on the good days.
Rusty.
