The June That Would Not Cool

A tram cleaner's private temperature notebook becomes a record of a city learning that heat is not a private problem.

Mara began writing down the numbers because nobody at the depot believed her when she said the trams were hotter at three in the morning than they had been at midnight. The supervisors shrugged, the drivers rolled their eyes with theatrical kindness, and the other cleaners said heat collected in metal the way bad luck collected in families. Mara wanted proof small enough to fit in her pocket.

Her notebook was the kind sold in packs of three near the cash register, blue cover, thin pages, a red elastic band that snapped against her wrist when she opened it. On the first page she wrote: Carriage 14B, 00:17, 31.8C. The little thermometer, meant for a kitchen, hung from a lanyard beside her spray bottle. She waited until the doors were closed, until the tram was silent except for the tick of cooling parts, then held the device at shoulder height and watched the digits decide.

By the third week of June she had filled half the notebook. Carriage 09A, 02:42, 34.1C. Carriage 22C, 03:08, 35.0C. Carriage 18B, 04:11, 33.7C, windows streaked with fingerprints, one seat damp with someone's spilled drink. She wrote other things too, though she did not call them data. Gum melted into the grooves by the doors. A moth stunned on the floor, alive but unable to fly. Two plastic flowers left behind after some celebration, their stems bent soft as cooked asparagus.

The depot lay behind a row of apartment blocks whose balconies faced the tracks like tired spectators. In winter, Mara could see television light blinking in the windows and hear the hiss of radiators when the night was very still. Now every balcony door stood open. People dragged mattresses toward the railings. A man slept in a chair with his feet in a laundry basket of water. Children appeared after midnight, pale and bare-legged, their parents too exhausted to scold them back inside.

At home, in the fourth-floor flat she shared with her younger brother Niko, the air was thick enough to lean on. They owned one fan, purchased years ago during a hot spell everyone had called exceptional. It made a clicking sound on its leftward turn, as if objecting to duty. Niko worked days in a warehouse and slept badly, one arm over his face, his T-shirt dark at the collar. Mara came in at sunrise and stood in the shower without turning on the heater. The cold water was not cold. It was only less warm.

On the radio above the sink, the morning voices had begun to use phrases that sounded both precise and helpless: hottest June on record, surface air temperatures, three degrees above average. One announcer said a monitoring service had measured western Europe at more than three degrees Celsius above the recent decades' norm. Another said the UK was entering its third heatwave of the year. France and Spain were mentioned with the word wildfire, a word that entered the kitchen like smoke even though the city sky was only white with glare.

Niko turned the fan toward Mara while she drank instant coffee over ice. "They always say record," he said, not in disbelief but in defeat. "Records are all they have left to give us."

Mara said, "Thirty-five in carriage 22C. At three in the morning."

He opened one eye. "You should write that to someone."

"I write it to myself."

"Yourself is not in charge of ventilation."

The corner shops began closing early. First the florist, whose roses blackened at the edges before they could be sold. Then the bakery, with a handwritten sign: Oven off until weather changes. The old mini-market stayed open but kept the lights dim, the owner sitting behind the counter with a wet towel around his neck. Mara bought tinned peaches there after work because they were cool from the back shelf, not because she wanted peaches. Outside, the asphalt gave off a smell like hot rope.

At the depot, adaptation came as rumors before it came as policy. There would be extra water bottles, someone said. There would be reflective covers for parked trams. There would be a new break schedule if the heat index passed a number nobody could define. Until then the cleaners continued to board the carriages after the last passengers left, collecting newspapers gone limp with sweat, bottles rolling under seats, wrappers stuck to the floor by softened sugar.

Mara's team worked in pairs, but the pairs changed. That week she was often with Osman, a widower who cleaned with delicate thoroughness, as if each carriage were a room where guests might return. He had a habit of naming the lost property. This umbrella is a diplomat. This lunchbox is a fugitive. This single sandal is an accusation.

When Mara showed him the notebook, he whistled. "You are making a weather station out of our misery."

"A weather station would have better handwriting."

He held the thermometer under a ceiling vent that breathed warm air. "Thirty-six," he said. "At least the tram is honest. My apartment lies. It pretends it will cool if I wait."

They laughed because the alternative was to listen to their own breathing.

The heat altered people's behavior in small, visible ways. Passengers stopped wearing jackets even to offices that required them. A woman in a business skirt rode barefoot one evening, shoes hanging from two fingers. Teenagers went quiet. Arguments on the platforms flared quickly and burned out, everyone too tired to sustain outrage. The public fountains became meeting places. Dogs refused to cross sunny squares. In the depot toilets, the mirror peeled at one corner, revealing a gray backing like old skin.

Mara kept thinking of the phrase scientists warned. It appeared everywhere now, attached to heatwaves and ecosystems and infrastructure, to tracks that could buckle, wires that could sag, lungs and hearts that could fail. Scientists warned sounded, to her, like a person knocking on a door behind which music played too loudly. She wondered how long they had been knocking. She wondered who had been paid not to hear.

One night near the end of June, the tram scheduled as 17D arrived with its interior lights flickering and a sour electrical smell under the perfume of disinfectant. The driver, a young woman named Lena, climbed down and pressed a bottle of water to her forehead.

"Don't go in yet," Lena told Mara and Osman. "It's an oven. The air cut out halfway from the terminus. Dispatch said bring it home if I could."

Mara opened the door anyway after a minute, because opening doors was what she did. Heat rolled over her face with the damp intimacy of a hand. The thermometer climbed so fast the digits blurred: 38.2, 39.0, 39.6. She wrote the time, then scratched it out and wrote it again more carefully. Osman stood beside her, silent.

On one seat lay a paper fan, folded from a timetable. On another, a child's drawing of a house with a yellow sun above it, the sun given sharp lines like teeth. No casualties, no drama, only evidence of ordinary people passing through an ordinary machine that had become temporarily hostile to them.

Mara stepped back onto the platform. For the first time the notebook felt less like a private defense and more like a message she had failed to deliver. Every number in it belonged not only to her, or to the depot, but to the passengers who had sat inside those sealed rooms on rails. To the man on the balcony with his feet in water. To the florist with ruined roses. To Niko under the clicking fan. The heat was not a mood. It was a condition imposed on everyone, though not evenly, and it was looking for the weakest parts of the city.

At break she photographed the pages under the fluorescent light. The pictures showed her thumb, the red elastic, the columns of times and carriages. She sent them to the union address printed on a poster near the lockers, then to the depot safety officer, then to a neighborhood group that usually argued about bins and bicycle lanes. Her message was short: These are inside-carriage temperatures from night cleaning shifts in June. Some are after midnight. We need a heat plan for workers and passengers before July is worse.

She expected nothing, or a polite reply, or trouble. Instead, by noon, while she was trying to sleep with a wet towel over her ribs, her phone began to tremble on the crate she used as a bedside table. Osman had forwarded the message to drivers. A driver had sent it to maintenance. Someone from the neighborhood group wanted permission to share the notebook photos at a tenants' meeting about cooling rooms. The union asked for the original entries. The safety officer replied with three lines and a promise to inspect 17D's ventilation before it returned to service.

Niko read the messages while Mara squinted at the ceiling. "Yourself is becoming influential," he said.

"It is only numbers."

"Numbers are how shy people shout."

That evening the city did not cool. The sun lowered, red and enlarged by dust, and the apartment blocks released the heat they had stored all day. Mara walked to work past the shuttered bakery, the dim mini-market, the florist's empty buckets stacked outside like silver bones. In the square, a volunteer from the tenants' association taped a notice to the library door: Late opening. Water available. Check on neighbors.

At the depot, a pallet of bottled water stood by the lockers. It was not enough, which did not mean it was nothing. A new sheet listed mandatory cooling breaks. Maintenance had parked three trams with their doors open and fans running, trying to purge the stored heat before the night crews entered. Osman greeted Mara by lifting his own notebook, green-covered, already labeled with carriage numbers.

"You have started a fashion," he said.

"A very boring fashion."

"Good. Boring things last."

They cleaned 14B together after midnight. The thermometer read 32.9C, still too high, still a number to write down. Mara noted the time, the carriage, the open doors, the fan placed at the far end. Outside, above the depot roof, the apartment windows glowed. Somewhere a baby cried and was comforted. Somewhere a chair scraped across a balcony. The city stayed awake, not from celebration or fear exactly, but from the shared labor of enduring.

Mara had once imagined emergencies as sirens and running feet. Now she understood that some arrived as a series of nights when sleep became impossible, when metal would not release the sun, when a private notebook filled with temperatures until it had to become public. She capped her pen. The page stuck slightly to the sweat on her palm. At the top of the next clean sheet, she wrote July.
