This chart of annual rainfall for the 12-year period shows 1997 and 2002 as the driest years (these were El Niño years) and 1995, 1998, 1999, 2003, 2007, and 2008 as the wettest years, with more than 200 inches rainfall for each of those years. Data were not collected earlier than April of 1992, so that year is expected to have a low total.
