The Lowdown
Alright, Rusty here. Let me read the tea leaves for this stretch of coast. We’re looking at a rough run ahead. Honestly, for the next 16 days, Honolii Beach Park is not playing nice. The forecast is a long, frustrating gap of onshore winds and messy conditions that just won’t let up. The first few days are a write-off, with poor surf and crummy wind direction hanging around for the first week. Things get a bit more interesting in the second week, but even then, it’s a struggle to find a clean window.
Right now, Saturday the 8th of August, we’ve got tiny 2 ft waves from the NE with a short 10-second period. The combined energy is weak (89), and with rain showers and onshore wind, it’s a flat, messy day. Forget it.
Sunday the 9th and Monday the 10th see a bump in size, with 5 ft to 6 ft waves from the E, but again, it’s cross-onshore and the period is short (8 seconds). The energy picks up a bit (405 on Sunday morning, 328 Monday morning) but still poor quality. The water temp is sitting at 80°F, which is only about 1°F warmer than average, so pretty normal for this time of year.
The whole first week is a rinse-and-repeat of onshore winds and poor surf. The energy levels climb a bit mid-week, hitting 862 on Friday the 14th morning from a 7 ft ENE swell, but the NE wind is 15 mph and it’s cross-onshore. Not good.
The biggest swell of the run hits Saturday the 15th of August with 8 ft to 10 ft waves from the E, and the energy spikes to 1500 (strong). But the wind is howling 25 mph from the NNW, cross-onshore and messy. At that size, it’s only for experts, and with that wind, even they’ll struggle. Honestly, with this kind of wind and size, this setup looks more interesting for kite surfing than paddle surfing.
Sunday the 16th of August is the closest we get to a standout. The wind switches to a cross-offshore breeze from the S at 25 mph (strong), and we get 8 ft waves from the E in the morning, with a solid 1861 energy reading. The description says “clean,” which is promising. But the period is short (8 seconds) and the swell is a bit much for a beach-and-river break. Still, Sunday morning is your best shot if you’ve got the skills and are desperate.
After that, the second week from the 17th to the 23rd of August is a downgrade. We get a few mornings with 5 ft to 6 ft waves and light cross-on winds, but the quality is poor or marginal at best. The energy stays moderate (300-400 range), and there’s no real clean window. Friday the 21st has 6 ft E swell with light cross-on winds, but it’s only marginal. Consistency is rare, and even the “good” days are a gamble.
The standout here? Without any doubt, it’s Sunday morning, August 16th at Honolii Beach Park. The cross-offshore wind gives you clean waves at 8 ft from the E, and the energy is huge (1861). It’s big and powerful, only for experienced surfers, and with that much energy and a short period, it’ll be a bit walled-up but rideable. Crowds are likely to be around, given it’s the best day in a long flat spell.
If you’re a beginner, stay home. The entire 16-day window is a mess for you.
Rusty out.
