Hawaii has two seasons worth mentioning -- summer and winter. And winter is better here than summers are in most places. Summer is the dry season in Hawaii, and winter is the rainy season. Don't expect too much variance in the weather during your trip. There is a reason they call this place paradise. It's mostly sunny, and a few scattered showers fall "up mauka," at higher elevations, just about every day. In short, it's really nice most of the time. The weather does vary somewhat when it comes to rain. Rarely do you have long downpours for days on end, but rain is definitely going to affect you more if you are staying at higher elevations, particularly on the windward (generally the eastern and northern) sides of the islands. On the leeward sides of the islands, you can expect sunny days and dry conditions normally. Temperatures year-round in Hawaii stay between 70 and 80 degrees Fahrenheit most of the time. In the summer, you can expect some 90-degree days, but weather much hotter than 90 is fairly rare. Hurricane season runs through the summer, but landfall for these storms is rare in Hawaii. The last hurricane to hit Hawaii was Iniki in 1992.
