The climate of Niihau (Hawaii
- United States of America)
Niihau is also known as The forbidden Isle. The island is owned by the
Robinson family. Because this family wants to preserve the original
culture the island is off limits to the public, unless you are
specifically invited by the family. The family tries to live in
accordance with the original Hawaiian traditions and standards as much
as possible. Because there is not much contact with its inhabitants
little is known about the island. Niihau has a tropical climate and is
located on the windward side of Mount Kaua’i. Because the island is
situated at a low altitude there are no differences in temperatures.
Precipitation figures are high all year round and precipitation is
evenly spread out over the year. During the slightly colder winters
precipitation figures may be extremely high.

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:
