What’s Up With Hawaii’s Wet Side and Dry Side Weather?
Also I read that there is a dry side and wet side. That sounds real weird but is it that different on the sides of the island, and why?
There is a dry side and a wet side of every island – generally east and north shores tend to be wet while south and west tend to be dry. It has to do with the way the wind comes in off the ocean (trade winds, usually comes in from the east). The clouds blow in, get pushed up the mountains that are in the center of every island, and dump all their rain before getting light enough to head to the other side of the island – something like that. If you are really interested read more here at wikipedia.
Generally the more popular destination spots like Waikiki, Kailua-Kona, Poipu, and Kaanapali get very little rain because they are on the dry sides. Puako on the Big Island can get 7 inches or less rain a YEAR – that’s like desert. Great for vacationers cuz they are not looking for rain usually Compare that with Hilo (where I live) where it seems like sometimes we can get 7 inches in a day and still not cancel soccer practice. lol.
