I think Hawaii and Alaska had never gone to 100°F, maybe that changed this year. I recall it hit 100°F here during the Olympics, we were at a baseball game when that happened, and it was a "dry heat" indeed, but HOT. Yesterday the humidity was 39% at 100°F, it was quasi-tolerable in the shade with a bit of breeze.
The place we stay in Hawaii is consistently a high of 82°F with no rain, they get 3 inches a year, I have seen it rain there. The weatherman has little to do. One nice thing is every day is generally the same, quite nice. Of course the other side of the island is quite different, I think Hilo gets 300 inches of rain a year. It's a pretty nice small town.
There have been some really bad tsunamis on that other side of the island in history, I'm glad the big quake didn't cause something bad. The outskirts of Hilo can be wiped out by the volcano, and subdivisions are gone with a house dotted around here and there, the other areas just an old lava flow. A main connecting road was swallowed up years ago and never redone. It's neat to drive to the end of it.
