Without a doubt Hawaii vacations are one of the most beautiful and exotic locations in the world and the Hawaii weather helps to make it one of the most popular tourist destinations as well. Temperatures in Hawaii tend to be very stable for the most part because the Islands themselves are surrounded by a vast, warm ocean. This makes all the air over the islands pass first over thousands of miles of ocean before it reaches the islands, and so if the air is coming from a cooler place, it warms up.
