Abstract:Historical rain gauge data were analyzed to identify average annual rainfall cycles
across the island of Oahu for different time periods. There are diverse microclimates in
Hawai‘i that are regulated by topography of the island and location relevant to the trade
winds and to the two mountain ranges, the Ko‘olau and Wai‘anae. Data sets were
acquired from active rain gauges maintained by USGS. The time periods that time series
plots were produced for are the two successive decades 1998-2007, 2008-2017, as
well as 2003-2017 and the most recent year, 2017. From data recorded in the last two
decades it is unmistakable that location and elevation have an affect on the climate.
Characteristics of the climate including the number of days it rains per month, as well as
the monthly and seasonal average rainfall patterns. Comparison of rain gauges that
were grouped into clusters based on geographic location show there is a distinct polarity
in average precipitation from the windward to leeward parts of the island.
