Updates in hr min s Forecast update imminent
Alright folks, Rusty here with the skinny on what's coming. We got one break to look at, so let's get into it.
Right now, the waves are pretty weak and small. The first few days are nothing to write home about, but the second week shows a bit of promise.
Lahaina Breakwall/Harbour (Maui) is the only game in town. The water temp is 80°, which is average for this time of year.
We kick off Friday, July 3rd. Clear skies, but the swell is tiny at 1ft coming from the SW with a very long 16-second period. The combined energy is moderate (114). The wind is a moderate offshore from the NE, so it'll be clean, but there's zero power. This same pattern of small, clean but weak surf from 1ft to 2ft SW swell holds all through the first week. The period drops from a super long 21 seconds on Saturday the 4th down to 12 seconds by Thursday the 9th. The energy stays moderate. On Thursday afternoon the 9th, it falls to a poor 1ft with only 47 energy—genuinely poor.
After that quiet couple of days, the surf finally wakes up around Monday, July 13th. That morning, the swell lifts to 2ft from the SW with a 15-second period and a better energy reading of 229. By Monday afternoon, the call is "expect good surf conditions" with a gentle offshore breeze keeping it clean. The energy jumps to 268. This is where it gets going.
The standout window is Tuesday and Wednesday, July 14th and 15th. On Tuesday morning, we've got 2ft of swell, but the direction shifts to the WNW with a very long 16-second period. The energy jumps to a strong 349, and the wind is a light offshore from the ENE. Glassy, clean conditions with some real grunt. Wednesday morning the 15th holds similar size and period, with a light cross-offshore breeze. The energy stays strong at 315. This is the best run by far. The swell direction matches the spot's optimum, and with the consistent offshore winds, the waves will be clean and have some push. Just a heads-up, it's a reef break and crowds are a possibility, so don't expect to have it to yourself.
After Wednesday, the energy backs off. The swell drops back to 2ft and 1ft for the rest of the forecast, with the period shortening and the energy falling back into the moderate range. Clean, but ordinary again through to the end on Saturday the 18th.
This is Rusty, out.
