The Lowdown

Alright, folks, Rusty here. Let’s be real – the next couple of weeks are looking pretty flat for the most part. We’re staring down a long stretch of small, weak surf. It’s going to be a test of patience, but there might be a tiny glimmer of something rideable by the end of it.

We’re looking at Anaehoomalu Bay_A-Bay (Big Island) as our only real option, and even that’s a stretch for a while. The water temp is sitting at 81°, which is about a degree and a half warmer than usual for this time of year – nothing crazy, but you’ll notice it.

The first week is basically a write-off. From Tuesday the 4th through to around the 11th, we’ve got almost nothing. Swell heights are hovering around 0.6ft to 1ft with periods all over the place, and the energy is weak – we’re talking single and low double digits in the combined energy (15, 11, 4, 12). It’s just not happening. There are a few glassy moments, especially on the afternoons, but you’d be fighting for a wave that barely breaks. It’s a long, flat stretch, and honestly, it’s going to be a grind.

Things start to stir a little bit around Thursday the 13th. We finally see a pulse of energy coming in from the WNW, with the swell at 1ft and the period jumping up to 15 seconds. That’s a proper groundswell, and the combined energy climbs to 71. It’s still small, but it’s something. The wind is looking light and cross-shore, so it won’t be perfect, but it’s a start.

Friday the 14th sees similar conditions, with the swell at 2ft and a 13-second period. The energy is moderate now, hitting 149 in the morning. The wind is a bit stronger out of the NNE, but it’s still manageable.

The standout, if you can call it that, is shaping up for Saturday the 15th. We’ve got 2ft to 2ft of west swell, still with that long 15-second period. The combined energy is up to 156, which is the strongest we’ve seen all window. The morning wind is light offshore, and by the afternoon it’s glassy. This is the best opportunity we get. It’s not big, but it’s clean and it’s rideable. This is the one to circle on the calendar.

Sunday the 16th and Monday the 17th keep the same swell size, but the winds are a bit more cross-onshore, so the quality drops off. It’s still surfable, but not as good as Saturday.

The energy stays moderate through Tuesday the 18th and Wednesday the 19th, with the swell remaining around 2ft to 2ft. The Tuesday afternoon session with a cross-offshore breeze might offer a clean window, but the Wednesday morning looks more crossed up.

So, bottom line: it’s a long, flat spell, but don’t completely give up. The weekend of the 15th and 16th is your best bet, with Saturday afternoon looking the cleanest. It’s a reef and point setup, so that long period swell should wrap in a little better than at a beach break. It’s an intermediate spot, but with waves this small, it’s not going to be too challenging. Just keep your expectations in check. This is a promise of better things, but it’s a long way off. We’ll see.

Rusty, out.
