Jarosite Reef Surf Forecast and Surf Report

Alright, Rusty here. Let's get into it. We've got a solid 16-day window with some real gems hiding in there, but you've got to be patient and pick your moments. This whole stretch revolves around one break: a heavy, exposed reef that demands respect.

The first real action hits us on Thursday, September 3rd. A strong SW groundswell is already pushing in, and while the morning is a bit of a write-off with rain and moderate cross-off winds, the afternoon cleans up nicely. We’re looking at a solid 15 ft swell from the SW with a long 14-second period. The wave energy is pumping hard – we’re talking 9,613 on the energy scale. This is serious, experienced-only territory. The wind goes clear and stays cross-off, so the sets will be lined up and powerful. Don’t even think about it if you’re not on your game.

Now, here’s where it gets good. Friday, September 4th is our first standout of the period. The wind swings offshore from the NW, light at 15 km/h, and the swell eases to a still-chunky 7 ft from the SW. The period stretches out to 16 seconds – that’s proper groundswell energy. The wave energy is still very strong at 2,387. For a reef break, that long period means long, walling lines and big gaps between sets. Paddling out will be manageable, but the drop is critical. This is top-tier, clean surf for those who can handle it. The water temp is about average for this time of year, nothing weird going on there.

Saturday the 5th gets blown out by strong 45 km/h offshore winds. The swell drops to 5 ft, but that wind makes paddling into anything a nightmare. It’s a skip day.

Sunday, September 6th serves up a much more manageable 5 ft SSW swell. The wind is light cross-off, and the energy is moderate at 921. The wave comment calls it "very good" – and for a smaller day on this reef, it could be a fun window for a wider range of strong intermediates.

Keep an eye on Tuesday, September 8th. Another long-period pulse arrives: 5 ft from the SW with a huge 18-second period. The wind is light WNW cross-off, making for glassy conditions. Wave energy is back up to 2,060. That long period on a reef like this means it will suck the water off the reef and pitch, but it could also be a bit fat and walled if it’s paired with the wrong tide. Still, a very promising morning.

The next true standout, and the absolute best on offer in the whole outlook, is Thursday, September 10th. Morning session. The swell jumps to 8 ft from the SSW, with that same long 18-second period. The wind is light 10 km/h from the west, giving you cross-off conditions. The energy is 4,634 – strong and powerful. The model calls it "excellent for experienced surfers," and I’m calling it the pick of the week. If you can only paddle out once, this is the window. Big, clean, powerful SW groundswell with proper wind. This is where you earn your stripes.

After that, the surf settles down. Friday, September 11th and Saturday, September 12th offer smaller, clean conditions with 5 ft to 5 ft swells and cross-off winds. Good for a cruise on a bigger board, but nothing to set the world on fire. A solid 30 km/h north wind on Saturday makes it a bit of a wrestle.

The second week gets patchy. There’s a big, proper pulse showing up on Wednesday, September 16th afternoon. Swell jumps to 13 ft from the SW, energy skyrockets to 10,462, and the wind is fresh offshore from the NW at 35 km/h. That is absolute mayhem. Only for the most committed adrenaline junkies. Before that, Tuesday the 15th afternoon has a clean 5 ft SW swell with offshore winds – a much safer bet. The rest of the week is a mix of messy cross-shore winds and smaller, chopped-up surf. The last real day to check is Thursday, September 17th morning, with a clean 6 ft swell and moderate offshore winds. After that, the window closes with a whimper.

So to wrap it up: the standout days are Friday morning September 4th and Thursday morning September 10th. The 10th is the heavyweight champion. For the more manageable stuff, Sunday the 6th and Tuesday the 15th afternoon are your best bets. This isn’t a beginners’ playground; this is a reef that demands a solid skillset and local knowledge. Treat it with respect.

Rusty.
