I used to live in Hawaii a long time ago. In my experince Jan-March were rainy months sometimes and sometimes not. I just got back from a cruise to Hawaii Sunday. We had bad weather 6 out of 7 days. It was either heavy clouds with no rain or like Thursday and Friday on Kaui constant rain on Thurs. and drizzle on and off on Friday. Of course the day we went home was bright and sunny. Figures!
