* Average as calculated by Western Regional Climate Center for period 1903-2019. Data for only 11 months of data were recorded for years 1903 through 1918 (therefore we do not include these years), and 62 months were missing data for 1919 through 2018, impacting these averages.
T = Trace amount
(1) Seasonal rainfall through latest full month.
(2) 26 days or more of data were missing for this month.
