On April 1, 2026, at Phillips Station, a crucial site for measuring Sierra Nevada snowpack, the California Department of Water Resources found nothing substantive to measure. April Fools’ Day be damned, the critical snow survey that state meteorologists use to predict the summer annually came back empty-handed: in other words: there was no snow.
The DWR saw its second-lowest April measurement on record; the measurement only came second, not first, because there was still a fine strip of visible snow covering some of the station grounds. The survey undoubtedly displayed a big loss for California, as the DWR’s report also stated that frozen reservoirs in the general Sierra Nevada region account for about a third of the state’s water needs.
Some have tied the record-low measurement to a “super” El Niño-driven, momentary “warm snow drought,” in which temperatures being too high cause intense early melting, if not full-blown rain-on-snow events.
With snow almost completely wiped away months ahead of schedule, hydrologists and water officials are concerned that something vastly worse may be underway.
“Our system relies a lot on snow right now,” Steven Ritchie, who oversees water system operations for the San Francisco Public Utilities Commission, told SFGATE. “We’re going to end up lower [in water] in October, and so going into next year, we’re going to be in more of a deficit than we usually are. We’ll see where we go from there. This could be the beginning of a drought.”
Drought in California and surrounding states is a historically common occurrence, one that usually lasts for several years at a time. Drought is a word that the average Californian is more than likely familiar with–regardless of geography or social status–and one they dread. Drought can permanently damage water supply and quality, with a prolonged absence of groundwater concentrating salts, reducing dissolved oxygen levels and increasing water temperatures heavily. Drought also routinely puts countless people below a certain tax bracket in rather precarious financial situations, not to mention the decline of lakes and rivers leading to the death—if not regional extinction—of countless fish and wildlife.
Not to mention the effects on agriculture, nor the energy costs. All in all, “drought” is a very loaded word.
There is also the reality that snowpack disappearing more than a month ahead of schedule would mean at least four more weeks of warm, dry conditions in a heavily forested, shrub-dominated region. The April 1 survey may have shown that the Sierra Nevada is becoming primed for big wildfires.
Wait a second, though—what is a super El Niño, or an El Niño in the first place?
An El Niño refers to warmer-than-average water temperatures along the equatorial Pacific coast, water temperatures that can impact weather patterns across the globe.
El Niños can raise the chance of blistering drought in some regions and severe rains in others. While for southern California, an El Niño usually leads to the latter, combined with the results of the April 1 survey, it’s looking increasingly likely that Oak Park will be facing a rather humid, unusually sweaty summer.
However, the simple climate events that standard El Niños are remain tentative on several environmental conditions that seem to be rapidly changing from year to year. If sea surface temperatures are raised high enough this year—which the National Oceanic and Atmospheric Administration has put at one in four odds of happening—a super El Niño does have a chance at generating.
Once the upper echelon of global climate phenomena hits polar and tropical jet streams, a wide array of things could occur on Californian, Canadian, Argentinian and Japanese soil alike. The NOAA has also stated that the amount of warm water available for a possible super El Niño event exceeds that of 1997-98, which was one of the strongest events of that century.
The super El Niño of 1997-98 was so strong, in fact, that it caused rapid floods in southern California for months straight, killed between 230 and 500 in Hurricane Pauline on Mexico’s southern coast and killed well over 500 in one of Indonesia’s worst droughts on record.
California seems to be in the middle of two meteorological extremes that may just come bumbling down towards each other in the months to come: landscapes drying out more than millions could bear, and rains falling much harder, earlier and longer than they ever should. The snowless ground on April Fools’ Day 2026 served as a stark warning: the environmental systems that California relies on, much like an updating computer program, are shifting. The margin for error is getting closer to zero.
