Why our “Rainfall Season” is different than that of the National Weather Service

* Although normals are established by the National Centers For Environmental Information, based upon averages for rainfall seasons 1991 through 2020 (updated May 4, 2021), this station's data only goes back to 2016, which is far less than the NCEI's typical 30-year data calculation period. NCEI does not provide normals for this station. Consequently, here we use NCEI normals from the nearest weather station (Fullerton Municipal Airport, 5 miles southeast).

(1) Seasonal rainfall through latest full month. Due to missing data for the first 3 months of the season, this total is incomplete.
(2) 26 days or more of data were missing for this month.
(3) Due to one or more months of missing data this season, cumulative numbers cannot reflect a complete season total.
