The 2022-2023 winter will go down in southern California as being a cool and wet winter, a rarity among the rapidly warming desert southwest. During the 21-day period stretching from December 27 through January 16th, Eaton Canyon picked up an incredible 13.31″ of rainfall. Immediate storm impacts to the park from this event were outlined in a previous article located here.
January 2023 in downtown Pasadena picked up 13.45″ of rainfall, our wettest month in over 13 years. Of all the winters of the past decade, only the 2018-2019 water year saw more rainfall than the 2022-2023 water year has, but we still have quite a way to go before the season is over. A very green spring is anticipated this year as a result of all the rain. Be sure to check out all the flowers, mushrooms and new growth in the canyon!
Here is a chart showing monthly precipitation in Old Pasadena since the start of the 21st century:
