Waimanalo Surf Forecast and Surf Report

G'day, Rusty here, and I've gotta be straight with you – the next couple of weeks for Waimanalo are a real bummer. We're looking at a solid stretch of nothing but poor surf conditions, with a big gap of flat, junk waves right at the start. The good news? The water temp is sitting at about 81°F, which is pretty spot on for this time of year, so at least a dip in the ocean won't be a shock to the system.

The outlook kicks off from Wednesday the 26th of August, and mate, it's a write-off. We're stuck with onshore ENE winds, and a weak, short-period swell (171 weak energy) that's just not doing anything. Those onshore winds don't let up for days, making for nothing but messy, bumpy conditions. The swell energy does pick up a bit, climbing to moderate levels (353) by the 29th, but the wind stays strong and cross-onshore, so it's just a lumpy, choppy mess. This pattern of onshore winds and poor surf just keeps rolling through the end of August and into early September.

The first few days of September are more of the same. The swell energy gets up there – we're talking strong stuff, with readings like 551 on the 1st of September – but the wind is still on it, and the swell period is a short 8 seconds. It's all power and no shape. The waves are around 6 ft to 7 ft, but with that onshore wind, it's just a washing machine. You'd be better off watching from the sand.

We finally get a bit of a change around the 4th of September. The wind swings to a lighter E and cross-onshore, but the swell drops off and the energy falls back to moderate (346). The wave comment for the 6th of September reads "marginal surf forecast," which is the closest we get to a glimmer of hope, but the swell is only 4 ft with a short 8-second period. It's a light cross-shore wind, but the waves are just too weak and junk to get excited about.

Looking further out, the 9th and 10th of September see a jump in swell energy again (544 and 609), but the wind is back up to a strong, onshore breeze. The swell period does stretch out to 12 seconds on the 10th, which is a better sign, but with that much wind, it's just going to be a messy, blown-out stormy surf. Not what you want to paddle into.

So, the whole 16-day window is a total dud for Waimanalo. There's no standout session, no hidden gem. It's a classic case of "leave the board in the car." The forecast can always change, but right now, this stretch of onshore winds and poor surf conditions is a real kick in the guts. Keep an eye on that wind, but for now, it's a no-go.

Rusty.
