Jarosite Reef Surf Forecast and Surf Report

G’day, this is Rusty.

Right off the bat, the next week and a bit is pretty grim for Jarosite Reef. We’ve got a couple of tiny, weak waves Monday and Tuesday, but they’re not worth getting wet for. The swell is only around 2ft, and even though the wind is cross-offshore, the energy is just too weak—the combined energy is a modest 166. The water’s sitting at 57°, which is pretty much spot on for this time of year, so no surprises there.

The first real pulse of size shows up on Tuesday the 15th, with the swell jumping to just over 8ft, but the wind swings cross-offshore in the morning (30 km/h) and then turns messy cross-shore in the afternoon. The combined energy is strong at 3957, but it’s not going to be clean. Wednesday the 16th sees that size hold around 8ft, but the wind is cross-on and choppy—this is more of a grinder than a surfer’s wave. It’s pushing close to 8ft, so it’s really only for the experienced crew, and even they will be fighting the chop.

Thursday the 17th drops back to around 5ft, but the wind is onshore again, and the energy is moderate at 1072. Not much to get excited about.

Now, here’s the standout of the whole window: Friday the 18th. That’s when things line up. The swell is around 4-5ft from the SW, the period stretches to 14-16 seconds, and we get a solid offshore NW wind at 20 km/h. The combined energy is moderate at 1181 in the morning, bumping to 1539 in the afternoon. This is going to be clean, lined-up, and proper. Jarosite Reef (Big Island) is a reef break that needs that offshore to really shine, and this is the best it’s going to get. It’s an advanced wave, and with the offshores, it’ll be glassy and hollow. This is the day to be out there.

Saturday the 19th is still okay—around 4ft from the SW with offshore winds, but the period drops a touch and the energy fades to 578 in the morning. It’s surfable, but not in the same league as Friday.

Sunday the 20th sees the wind remain offshore but the energy is weaker, around 736, and the size is down to 4ft. It’s rideable, but with a marginal forecast. Monday the 21st has a little more size (just under 6ft) and a light cross-offshore in the morning, which is good, but the afternoon turns cross-on.

Tuesday the 22nd is another decent run—around 6ft from the SSW with a nice 15-second period and offshore/cross-offshore winds. The energy is strong (1860 in the morning) and the conditions are clean. This is the second standout, but it’s a step below Friday because the swell direction is a bit more south in the mix.

After that, things taper off. The size drops to under 3ft by Wednesday the 23rd, and the energy collapses. The rest of the period (from around the 24th) goes quiet. There is a pulse around the 26th-27th with 5-6ft, but the wind is cross-on and the period drops back to a stormy 17-18 seconds, which is messy at a reef.

And then we get one last tease around the 29th—a long-period SW swell (17-18 seconds) at around 5-5ft, but the wind is cross-on from the ESE, and the energy is moderate (2267-2468). It’ll be pretty, but the cross-on breeze will chop it up.

So, to sum it up: if you only surf one day in this whole 16-day run, make it Friday the 18th. The second pick is Tuesday the 22nd. Everything else is either too small, too windy, or too messy. The long gaps between quality days are a drag, but when that Friday comes through, it’ll be worth the wait.

Stay stoked.

Rusty.
