There is a particular quality to Chicago’s cold that resists metaphor. It is not the sharp, clean cold of mountain air, nor the damp chill of a coastal fog that softens the world at its edges. It is a cold that arrives with intent — a flat, grey, philosophically committed cold that seems less interested in temperature than in making a point about the nature of endurance. After five consecutive months of this, the National Weather Service’s Chicago office issued a first-of-its-kind “Existential Despair Advisory” on Wednesday, confirming what 2.7 million residents have quietly suspected since November: this was the winter that finally, irreversibly broke Chicago’s collective spirit.

It is worth sitting with that phrase — “broke the spirit” — because Chicagoans do not use it lightly. This is a city that has made survival into an identity, that wears its winters the way other cities wear their architecture: as proof of character. To break that is to crack something foundational.

“We’ve been tracking morale data alongside wind chill and precipitation since October, and the numbers are simply unprecedented,” said NWS meteorologist Linda Gutierrez during a press briefing held inside a heated tent because the office furnace gave out in January and never came back. Her breath was visible as she spoke, each word arriving as a small ghost before dissolving into nothing. “Chicagoans are famously resilient. They take pride in surviving winter. But our instruments are now measuring citywide despair at levels we previously thought were only theoretical.”

The advisory, which covers Cook County and the surrounding collar counties, recommends that residents “avoid looking at weather forecasts for any period exceeding 24 hours,” “refrain from comparing current conditions to cities in warmer climates,” and “under no circumstances Google ‘average winter temperature in San Diego.’” There is something almost tender in these instructions — the weather service, itself a victim, trying to shield the public from further harm.

The winter of 2025-2026 has been remarkable by even Chicago standards. A polar vortex in December delivered 18 consecutive days of sub-zero temperatures — days in which the sky took on the color of old pewter and the lake exhaled plumes of steam into the air like the breathing of some vast, cold-blooded thing stirring beneath the surface. January saw a record 47 inches of snowfall, including a single 19-inch storm that the Tribune memorably headlined “ENOUGH.” February brought freezing rain, a surprise sleet storm on Valentine’s Day that seemed almost personally vindictive, and what meteorologists classified as “spite wind” — sustained 40-mph gusts that appeared to serve no meteorological purpose other than making people miserable. Even the wind, it seemed, had grown cruel for its own sake.

“I’ve lived here my whole life. Fifty-three years,” said Portage Park resident Donna Miklaszewski, standing at a bus stop on Milwaukee Avenue wearing four layers and what appeared to be a sleeping bag fashioned into a scarf. The streetlight above her buzzed and flickered, casting her shadow in uncertain intervals, as though even the light couldn’t decide whether to stay. “I used to say, ‘The winter makes us tough.’ I don’t say that anymore. The winter won. I’m looking at condos in Tampa.” She said this without bitterness — just the calm, clear-eyed resignation of someone who has finally stopped arguing with the sky.

Mental health professionals across the city report a surge in what they’re calling “Seasonal Existential Disorder,” or SED, which differs from standard Seasonal Affective Disorder in that patients don’t just feel sad — they begin to question “the fundamental logic of choosing to live in a place where the air hurts your face for five months a year.” It is a disorder born not of chemistry but of philosophy: the slow realization that suffering, when it persists long enough, begins to feel less like a season and more like a condition of existence.

“My caseload has tripled since November,” said Dr. Robert Chen, a psychologist practicing in Lakeview. “The most common thing I hear is, ‘I used to think people who moved to Austin were quitters. Now I think they were visionaries.’ That level of ideological collapse is very difficult to treat.” He paused and looked out his office window at the grey sheet of sky that had been hanging over the city since October like a thesis statement. “You can’t prescribe sunlight,” he added quietly. “Not here.”

The city has responded by deploying “Warmth Ambassador” teams to CTA stations, distributing hot chocolate and pamphlets titled “Spring Is a Real Thing That Will Actually Happen.” Mayor Johnson has also declared a citywide “Resilience Week” in early March. A spokesperson said the mayor “will be leading Resilience Week personally and has requested extra hot chocolate for all city employees.”

And yet — and this is the thing about Chicago, the thing the winter can crack but never quite shatter — people were still at the bus stops. Still waiting, still layered, still breathing visible breaths into the iron air. Spring will come, as it always does, sudden and almost violent in its greenness, and the city will forget, as it always does, that it ever doubted. But for now, the cold remains, and the people remain in it, and there is something in that stubbornness that the weather, for all its fury, has never quite been able to explain.
