Waimanalo Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on offer for Waimanalo over the next couple of weeks.

Right off the bat, I gotta be straight with you – this stretch is looking pretty grim. The first week is a write-off. We’ve got onshore or cross-onshore winds blowing from the ENE, mostly in that 18 mph range, and it’s making a mess of things. The combined swell energy is moderate to strong, hitting values like 327 and 375 towards the weekend, but it’s all short-period windswell at 6 to 7 seconds. The wave comment says it all: “poor surf conditions.” The water temp is sitting around 81° with a tiny anomaly of +0.7°, so that’s just about average for the time of year.

That poor run keeps going right through the first week and into the start of the second. We’re looking at nearly a full week of dud surf. The wind does ease slightly into the first days of September, dropping to a moderate breeze around 12-15 mph, but the swell is still onshore and messy. The combined energy peaks at 533 on Wednesday, 2nd September, but it’s all onshore junk. Honestly, this setup looks more interesting for kite surfing than paddle surfing.

Now, hang in there, because there’s a glimpse of hope right at the end of the forecast. On Wednesday, 9th September, things change. We’ve got a 4 ft to 5 ft swell coming from the east, swinging to the ESE, with a period jumping to 12 seconds. That’s a proper groundswell folks. The combined energy is strong at 469 and 539, and the wind shifts to a gentle breeze from the ENE, going light and even offshore-ish from the NE. The water’s still clean. This is the standout. The swell is modest, but that long period and cleaner wind will make for some lined-up waves, ideal for a point break or reef. Keep in mind, with a period over 11 seconds, it’s a groundswell and can be very straight at a beach break, but this spot is exposed to the NE. It’s not a big swell, so it’s fine for most levels, but crowds are possible here.

The following morning, Thursday 10th September, still looks promising with a 3 ft to 4 ft easterly swell, 12-second period, and a light breeze from the E or ENE. The combined energy is 384 to 415. It’s smaller, but clean. So, the best bet is this Wednesday-Thursday window next week. Long range, so not 100% locked in, but it’s the only real chance we’ve got.

Rusty, signing off.
