However, Anza's season total is not considered to be accurate due to overreporting rainfall in December, and that season total is likely around 3 inches higher than it should be (roughly 9 inches). Season totals exceeded 12 inches at two WeatherCurrents stations, in Simi Valley and Anza. Much of the region last saw measurable precipitation in April. A small number of mostly weak systems managed to pad season totals in February and March, with one thunderstorm-laden event in late March being somewhat notable. November was kept dry by a persistent blocking pattern throughout the entire month, and following the region's wet December, a stubborn dry pattern once again gripped much of the entire state in January - and for most of the remainder of the water year. Outside of those two months, remained a largely inactive, quiet rainy season.


October 2021 was the only other month of the season with even semi-consistent storm patterns. For virtually all locations across the region, December 2021 was the wettest period of the winter, where a significant portion of the season's total rainfall fell alone. Most WeatherCurrents stations with accurate season totals finished the 2021-2022 water year with less than 10 inches of rainfall - however, in the majority of locations, seasonal rainfall for 2021-2022 still exceeded that of the previous year, 2020-2021. California witnessed another La Nina winter, for the second time in a row during the 2021-2022 water year, with the resultant seasonal rainfall for much of the region once again ending below-average.
