The Winter season in America's 50th state brings continued warm temperatures, huge ocean waves (it's a total dream for seasoned surfers — and for spectators!), and prime humpback-whale watching. The climate might be a tad wetter from December through March, but rain typically arrives in short spurts, and that's a meager price to pay to unwind on a small slice of untamed paradise. Plus, if you've never seen a rainbow illuminating the Hawaiian sky, you're in for a treat!
