Waimanalo Surf Forecast and Surf Report

Alright, Rusty here. Let’s be straight with you: the outlook for the next 16 days at Waimanalo is a long, tough stretch. The forecast is persistently calling it poor surf conditions, and I gotta say, it’s looking like a bit of a write-off for now.

The first recommendation doesn’t come up until Sunday the 19th, and even then, it's not a good one. We’re looking at a 5ft swell from the ENE with a short period of 8 seconds, and a nasty onshore wind blowing at 19 mph. The combined energy is a weak 284, so there’s no punch to it. The water is sitting at 80°, which is pretty much normal for this time of year. This is a beginner-friendly, exposed beach break, but with these conditions – onshore wind and short-period, weak swell – it’s just not going to be surfable. This pattern sticks around.

From Sunday the 19th right through to the end of the month, we’re seeing the same story. The swell hangs around 4ft to 6ft, all from the ENE or NE, with periods that stay short, between 6 and 9 seconds. The wind is locked in from the ENE at 16 to 25 mph, almost always onshore or cross-onshore. Combined energy climbs from the low 200s up to 630 by the 31st, but it’s all wind-driven, messy junk. The break is inconsistent, and with that constant onshore breeze, it’s never going to clean up.

There’s a bit of a change on Sunday the 26th. The swell drops to 4ft, but the period jumps way up to 16 seconds. That’s a very long period groundswell, pushing energy up to 955. The wind backs off a touch to 12 mph, but it’s still onshore. For a beach break, a 16-second period swell like this will likely break too straight and be hard to line up. It’s a tease, but not a session.

The 28th of July sees the combined energy peak at 1230, with a 6ft, 13-second swell from the ENE. The wave energy is strong, but the wind is still a fresh 19 mph onshore. The 29th and 30th are similar, with energy staying in the 900-1000 range, but the persistent onshore wind kills any chance of quality. This setup looks far more interesting for kite surfing than paddle surfing.

The final few days into August, the swell fades to 3ft or less, but the period stays long (16-17 seconds). The wind stays cross-onshore, and the energy drops to around 680-770. There’s no standout session anywhere in the window. The break is fairly consistent for swell, but the wind is the enemy here. It tends not to stay this poor for long, so forecasts can change, but for now, it’s a blank run.
