Waiehu beach park Surf Forecast and Surf Report

Alright, Rusty here, checking the waves for Waiehu beach park. This is a reef and point break, consistent, and a good one for beginners when it’s right. Water temp is about 80°, dead average for this time of year.

The first week and a half is a tough one. From Tuesday the 11th all the way through to the morning of Saturday the 15th, it’s a constant onshore trade wind. Swell heights are between 4 and 6 feet, but the period is short, 7 to 9 seconds, and the energy is weak to moderate (192 to 548). The word is “poor surf conditions” – choppy and messy. Not worth the effort.

Saturday the 15th gets real nasty. Wind picks up to 22 to 25 mph, swell jumps to 8 to 10 feet, but it’s still cross-onshore, with energy getting strong (1409 to 2109). It’s described as “lumpy” and “messy.” That’s blown out and way too big for a beginner spot.

Now, hold on. Sunday afternoon, August 16th, that’s the one. The wind swings to a light cross-offshore breeze from the southeast at 9 mph. The swell is a solid 12 feet from the ENE, with a 10-second period, and the combined energy is very strong (2452). The report says “excellent surf conditions for experienced surfers.” This is your standout. A reef and point with that size and clean offshore wind? That’s a proper session for the experts. 12 feet is big, so only for the crew who know what they’re doing.

After that, it’s back to the trades. From Monday the 17th through to the end of the run on the 26th, it’s a long, sad stretch of cross-onshore winds, smaller swell between 3 and 5 feet, short period, and weak to moderate energy (100 to 317). The word is “poor surf conditions” for almost every session. A long gap of flat, choppy junk.

So, the whole run is a dud until Sunday the 16th afternoon. That’s your one golden window. The rest is a long, onshore wait. But that one session? Looks like a hell of a wave.

Rusty.
