Alright folks, Rusty here. Let’s look at what’s on the table for the next 16 days at Rivermouth_Wailuku.
Straight up, this is a tough stretch. The entire 16-day window is a write-off for quality surf. The wind is locked in from the ENE, blowing cross-onshore the whole time. That means the surface is going to be choppy and messy from Friday the 3rd of July right through to Saturday the 18th of July. There’s no standout day, no window for clean conditions – it’s all poor surf.
The swell hangs around the 4 ft to 6 ft range for the first couple of weeks, mostly from the ENE with a short, weak period of 6 to 8 seconds, so the energy is weak to moderate. There are no long-period groundswells to save the day. On Monday the 13th of July, the swell direction swings to the WNW with a long 16-second period, but the height is a tiny 1 ft, so that’s not going to do anything, and the wind is still cross-onshore with rain showers.
The water temp is sitting at a warm 79°F with a small anomaly, so that’s about average for the time of year. Not a detail that will help the waves though.
Rivermouth_Wailuku is a reef setup that’s fairly consistent and exposed to the swell, with the optimum direction being NNE. The swell coming in is from the ENE and NE, which is off-angle. The crowds here are often an issue, but with conditions this poor, you might have it to yourself anyway.
Honestly, there is nothing worth paddling out for across this whole forecast period. The cross-onshore wind ruins every session. I’d leave the boards in the shed and find something else to do. Forecasts can change, but this looks like a long, flat, choppy run.
Rusty.
