Weather on all of the Hawaiian Islands is very consistent, with only minor changes in temperature throughout the year.

This is due to year-round warm sea surface temperatures, which keep the overlying atmosphere warm as well.

In practical terms, there are only 2 seasons: the summer months (called Kau in Hawaiian) that extend from May to October and the winter months (Ho'oilo) that run from November to April.

The average daytime summer temperature at sea level is 85 degrees F. (29.4 C) while the average daytime winter temperature is 78 degrees (25.6 C). Temperatures at night are approximately 10 degrees F. lower. 

The islands are an incredible collection of many diverse micro-environments, each with its own unique weather, plants and animals. As a result of the shielding effect of volcanic mountains and the differences in weather found at various elevations, there are as many different climate zones here as exist along the entire coast stretching from Alaska to Costa Rica.

For the full impact of this, visitors need only explore the islands by car or helicopter and they'll see the beauty of tropical rain forests, cool alpine regions, stony deserts and sunny beaches - all within the span of just a few short miles.
