Waimanalo Surf Forecast and Surf Report

Alright folks, Rusty here. Gotta be straight with you – the next couple of weeks are looking pretty grim for a decent paddle. The data is telling me that, for the period starting now and running through the next 16 days, there’s just nothing on offer that’s worth getting excited about. We’re looking at a solid 16-day stretch of poor surf conditions at Waimanalo.

The first recommendation doesn’t even pop up because the quality is so low. The water temp is sitting at 79°, which is bang on average for this time of year.

Diving into the daily grind: Starting Tuesday the 14th, we've got a 4ft swell from the NE, but it’s a weak, short-period 7-second windswell, and the wind is onshore at 12 mph. The combined energy is a weak 219. It’s just messy. That pattern basically holds through the rest of the week. Wednesday the 15th, Thursday the 16th, Friday the 17th... all the same story. Cross-onshore to onshore winds, mediocre 3ft to 4ft swell, and energy levels staying in the 100s. The setup is more interesting for kite surfing than paddle surfing.

The weekend of the 19th and 20th doesn’t offer any relief. Saturday the 18th sees a jump in wind to 22 mph, making for a lumpy, choppy mess with a 5ft swell. Sunday the 19th has a slightly better-looking 5ft swell from the east, but the 19 mph cross-onshore wind ruins it. The energy is climbing into the moderate range (362), but it’s useless.

The second week is more of the same grimness. The wind just doesn’t let up. From Monday the 21st through to Wednesday the 29th, we’re looking at persistent onshore to cross-onshore breezes, mostly in the 16-22 mph range. The swell height fluctuates between 4ft and 6ft, and the period stays short. The energy levels do get quite strong by the 25th and 26th, hitting 508 and 655, but the wind is hammering it. The only standout is a bit of a tease on Monday the 27th, where the swell period suddenly jumps to 14-15 seconds – that’s a very long period groundswell. The combined energy is a massive 741, but it’s only a 3ft swell. That long period on a beach break with a 16 mph onshore wind is going to be a straight, close-out mess. No good.

So, bottom line: there are no good surf options in this 16-day window. The winds are consistently strong and onshore, and the swell quality is just poor. At Waimanalo, a blank run like this is more normal for the area when the trade winds get locked in. For now, keep the board in the car and wait for the forecast to change.

Rusty.
