Kewalos Surf Forecast and Surf Report

G'day, I'm Rusty. Let's look at what's coming up for the South Shore. It's going to be a bit of a mixed bag, but we've got a couple of windows that are worth getting excited about. The water temp's around average for this time of year.

Right now, through this coming week, we're looking at pretty small, clean conditions at Kewalos, but it's mostly marginal with questionable tide. Sunday the 13th is tiny, with a 2ft SW groundswell (226 combined swell energy) and a 15-second period, but the wind's a clean cross-off from the ENE. Monday the 14th and Tuesday the 15th stay small, under 2ft, with that long-period SW groundswell. The energy builds through the week, with Wednesday the 16th showing 3ft SW swell and the combined energy hitting 562-653, but it's still just on the edge of being worthwhile. The wind stays clean, which is a positive, but the size is lacking.

Then we hit a bit of a change. Thursday the 17th sees the swell pick up, but it's not great. We get a 7ft short-period ENE windswell with a period of just 7 seconds and a combined energy of 842. The wind is a fresh cross-off, but the wave quality is poor. By the afternoon, it's 7ft from the ENE with a 10-second period and energy jumps to 1376. This is more size, but the short period and direction aren't ideal. Friday the 18th is a write-off with a risk of thunderstorms and a cross-shore wind that'll chop things up. Saturday the 19th and Sunday the 20th stay in that 6ft to 7ft range of short-period ENE swell, but it's a clean cross-off wind. The energy is moderate to strong, but the quality is marginal at best.

Now, there's a gap of a few days through the middle of the week, from Monday the 21st to Thursday the 24th, where the forecast is consistently poor or marginal. The swell stays around 5ft to 7ft with short periods and a fresh cross-off wind. Not worth getting out of bed for.

The real standout in this whole outlook is the very end. Looking out to Monday the 28th of September, we've got a promising change. The morning shows a 6ft ENE swell with an 8-second period (700 combined energy), but the wind is a dead calm glass-off from the SE. That's a major positive. The forecast says "expect very good surf conditions" and the wave state is glassy. This is the one to circle on the calendar. It's a long-range call, so there's less certainty, but if it comes together, it'll be clean and fun. Crowds are often an issue here, so you'll want to be early.

Alright, signing off. Rusty.
