2021 Spring Package

  • Published: February 24th, 2021

Ready or not, next week brings us the first day of March and the beginning of meteorological spring. In our analysis of 243 cities across the U.S., 120 cities (49%) have recorded an increase in average spring temperatures of 2℉ or more over the past fifty years. Further, 96% of cities (234) reported an increase in the number of above-normal spring days since 1970, with 81% of cities (196) reporting an increase of 5 days or more.

Warming spring temperatures follow a pattern of warmer seasons encroaching on the cold of winter—resulting in an earlier advent of spring and throwing timing of natural events into misalignment. For instance, earlier snowmelt can result in changes in water availability and challenges to the breeding of native fish. Earlier spring temperatures can also lengthen the growing season, supporting longer pollen allergy seasons that start earlier and stick around for longer.
