Alright folks, Rusty here. Gotta be straight with you – the outlook for Rivermouth_Wailuku over the next 16 days is a tough one to swallow.
We’ve got a solid run of swell on the cards, with wave heights sitting around the 5ft to 6ft from the ENE and NE, and the combined energy is mostly moderate, bouncing between 277 and 480 (moderate wave energy). That sounds promising, but the problem is the wind. Day in, day out, it’s blowing cross-on from the ENE or NE at 9 to 16 mph. That’s an onshore breeze that’s going to chop things up and keep conditions poor right through the whole stretch. The water temp is sitting at a warm 80°, which is pretty average for this time of year, so at least you won’t need a wetsuit.
So, starting Sunday morning, July 5th, right through to Monday morning, July 20th, it’s a flat-out grind of poor surf. There is no standout day in this whole 16-day window. Every morning, every afternoon – it’s the same story: cross-on wind and choppy surf. The short period of 7 to 8 seconds means these are windswells, not the sweet groundswells we dream about. Even when the swell bumps up to 6ft around Friday the 17th and Saturday the 18th, the wind just kills it.
Honestly, with these conditions, this setup looks more interesting for kite surfing than paddle surfing. If you’re on a surfboard, you’re fighting an uphill battle. The consistent swell means it tends not to stay this way forever, and forecasts can change, but for now, there’s nothing to get excited about. The crowds are often there at Rivermouth_Wailuku, but with surf this average, they might not be.
Stay patient, folks.
