California is Free of Drought for The First Time in 25 Years
By Clara Harter
- After experiencing one of the wettest holiday seasons on record, California hit a major
- milestone this week — having zero areas of abnormal dryness for the first time in 25 years. The
- data, collected by the U.S. Drought Monitor, is a welcome nugget of news for Golden State*
- residents, who in the last 15 years alone have lived through two of the worst droughts on record,
- the worst wildfire seasons on record, and the most destructive wildfires ever. Right now, the
- wildfire risk across California is “about as close to zero as it ever gets,” and there is likely no
- need to worry about the state’s water supply for the rest of the year, said UC climate scientist
- Daniel Swain. Currently, 14 of the state’s 17 major water supply reservoirs are at 70% or more
- capacity, according to the California Department of Water Resources.
- California’s last drought lasted more than 1,300 days, from February 2020 to October 2023,
- at which point just 0.7% of the state remained abnormally dry, thanks to a series of winter
- atmospheric rivers that showered the Golden State with rain. Before that, California was in a
- severe drought from 2012 through 2016. But the last time 0% of the California map had any
- level of abnormally dry or drought conditions was all the way back in December 2000. In recent
- weeks, a series of powerful winter storms and atmospheric rivers have swept across California,
- dumping heavy rain that soaked soils, filled reservoirs, and left much of the state unusually wet
- for this time of year. “This is certainly a less destructive winter weather than last year was,”
- Swain said. He noted, however, that “as we move forward, we do expect to be dealing with
- increasingly extreme [weather] swings.”
- Though it may seem counterintuitive, climate change is forecast to lead to both more
- intense droughts and more intense episodes of rainfall. This is because a warmer atmosphere
- pulls more moisture out of soils and plants, deepening droughts. At the same time, a warmer
- atmosphere holds more water vapor, which is then released in fewer, more extreme rainstorms.
- Scientists have coined a name for this phenomenon — the atmospheric sponge effect — which
- Swain said is “hopefully an evocative visual analogy that describes why, as the climate warms,
- we actually are likely to see wider swings between extremely wet conditions and extremely dry
- conditions.” A key example of this effect is the weather pattern in the run-up to the devastating
- Palisades and Eaton fires last year.
- In 2022 and 2023, California experienced extremely wet winters. Mammoth Mountain, for
- example, set an all-time record for snowfall in the 2022-23 season. But then Southern California
- experienced one of the driest periods on record in the fall and winter of 2024, which enabled the
- subsequent devastation of January 2025’s firestorm. Much of the West has seen
- warmer-than-average temperatures and relatively little snow so far this winter. Research
- published in the aftermath of the fire examines how this extremely wet to extremely dry weather
- sequence is especially dangerous for wildfires in Southern California because heavy rainfall leads
- to high growth of grass and brush, which then becomes abundant fuel during periods of extreme
- dryness. Fortunately, California should be clear of water supply risks and wildfire danger for
- several months to come, Swain said, but in the long term, residents should expect to see more
- of this weather whiplash.
*California can be referred to as “The Golden State”.
