Agate and Pearl Street Surf Forecast and Surf Report

Alright folks, Rusty here, giving you the full rundown on what we're looking at for the next couple of weeks.

Overall, it’s a slow start. We’ve got a lot of small, wind-affected surf on the horizon, so you’ll need to be patient. The first real opportunity doesn’t show up until the first weekend of September, but there is one standout session that’s worth circling on the calendar.

We’re starting off at Agate and Pearl Street (Oʻahu). Right out of the gate, it’s bleak. Monday the 31st through the rest of this week is mostly small, onshore slop. Swell heights are around 2ft to 3ft from the south and southwest, with periods around 11 to 12 seconds. The wind is mostly onshore, so the water’s a mess. The wave energy is low to moderate, sitting between 204 and 387 for those first few days, and the calls are all poor or marginal. Not worth paddling out.

Things start to look a little more interesting heading into the first week of September. The swell starts to build, but we’ve still got cross-onshore and cross-shore winds messing with the shape. By Thursday the 4th and Friday the 5th, we’ve got waist-chest high swell around 3ft to 3ft from the south-southwest, with a longer period pushing 16-17 seconds. The energy climbs up into the moderate range (540 to 615), but the wind is still a problem, leaving a cross-chop on the surface.

Now, for the standout. Mark your calendar for Sunday, September 7th. That afternoon, things come together. The wind drops to dead calm, it’s glassy as a lake, with a 5ft south swell rolling in at a 14-second period. The wave energy hits a strong 1009, and we’ve got excellent surf conditions for experienced surfers. Agate and Pearl is a reef break, so this long-period groundswell will set up nicely if the direction holds. The water is a warm 76°F, which is much warmer than normal for this time of year – you won't need a thick wetsuit.

Monday the 8th and Tuesday the 9th are still rideable but take a step backward with the wind. Swell stays in the 5ft to 4ft range, but the wind switches and gets messy, with moderate cross-shore and cross-onshore conditions dragging the quality down.

After that, it’s a long, quiet stretch. From Wednesday the 10th all the way through to Tuesday the 15th, the surf fades away. Swell heights drop back to under 3ft, the periods are all over the place, and the wind stays onshore or cross-onshore. The energy readings sink back into the weak to low-moderate range (123 to 423). Honestly, it’s a blank run of poor surf conditions. For that whole second week, you’re likely better off doing something else unless you just want a splash around on a foamie.

If you’re a hardcore local, that Sunday the 7th is the one window worth chasing. Stick to that, and you’ll get the best of what’s on offer.

Rusty.
