Alright folks, Rusty here. Gotta be straight with you – this next stretch is a tough one to write. We're looking at Rivermouth_Wailuku, and the outlook is pretty grim. I'm looking at a solid 16-day run starting now, and honestly, there's not a single decent wave on the cards for the entire period. We've got a constant cross-onshore wind from the ENE, blowing at 9 to 16 mph, just chopping everything up. The swell is mostly in that 4 ft to 6 ft range, coming from the same direction as the wind, which is never a good sign. The period is short, between 6 and 8 seconds, so there's no real power behind it. Wave energy is weak to moderate, sitting between 187 and 408. It's just poor surf conditions, day after day.
For the first week, from Saturday the 4th right through to the following weekend, it's the same story – bumpy, messy, no shape. The water temp here is sitting at a very warm 79°, which is about average for this time of year, but you won't be enjoying it anyway. We move into the second week, and honestly, it doesn't get any better. From Monday the 13th all the way through to Sunday the 19th, the wind stays cross-onshore, the swell stays short and weak, and the conditions stay poor. There's no standout, no hidden gem, no window of opportunity. It's just a long, flat, choppy stretch. If you're really itching for something, this setup with the constant wind and short, choppy waves at this beach-and-reef setup might actually be more interesting for kite surfing than paddle surfing. For us surfers, it's a blank run. Forecasts can change though, so don't throw the board in the shed just yet.
Rusty.
