The climate of Maui (Hawaii
- United States of America)
Maui is the second largest island of Hawaii. The island was formed by
volcanic eruptions. Because of this it is shaped quite oddly. Maui is
very popular among nature lovers. From the island you can spot
humpback whales or go diving or snorkeling. The underwater world is
astonishingly beautiful. Several nice old villages can be found on the
island as well. The historic city of Iahaina is well worth visiting.
Just like the rest of Hawaii Maui has a tropical climate. because of
the presence of mountains there may be large differences in
precipitation figures. The western part of Maui is located on the
leeward side and is fairly dry. East from the mountains it is much
wetter. Because of the shape of the mountains there is a unique
phenomenon on Maui, the so called Maui Vortex. This phenomenon causes
the wind to be forced along the northern slopes of mount Halaekalã. On
the west side of this mountain it collides with Maui and is forced
south. Because the wind is forced through a valley wind speeds rapidly
increase. The downward breezes from the summits wipe out the clouds
which explains why rainfall is uncommon here.

More climate information
Climate figures are very useful but don’t present a general impression
of the climate and the eventual weather circumstances within a certain
period. The figures don’t always reflect the chance of wintry weather,
extreme heat or hurricanes. That is why we offer useful extra climate
information for each month of the year:
