Dehradun Weather Today: Cold Mornings, Clear Skies Likely

Dehradun, the Doon Valley's emerald embrace, greeted residents with a familiar winter nip on December 5, 2025, as temperatures hovered at a brisk 6.5 degrees Celsius at sunrise, ushering in a day of cold mornings and mostly clear skies. The India Meteorological Department (IMD) forecasted a high of 18 degrees Celsius with 80 percent sunshine, but the early chill—coupled with light fog reducing visibility to 400 meters—painted a picture of typical early December in Uttarakhand's capital. As the first rays pierced the mist over Robber's Cave, locals bundled in woolens for their morning walks along Paltan Bazaar, the air crisp with the scent of pine and woodsmoke from hillside hearths. "Dehradun's winter is like a gentle giant—chilly mornings that warm your soul by noon," quipped meteorologist Dr. Ritu Sharma of IMD's Dehradun station, noting the day's low humidity at 65 percent and winds at 5 km/h from the northwest. With no rain in the forecast and pollution levels at a moderate AQI of 120, the weather offered a respite from November's smog, allowing the valley's 8.5 lakh dwellers to savor the season's subtle symphony. As schools resumed post-holidays and offices stirred, Dehradun's blend of cold starts and clear afternoons promised a balanced day, a prelude to the hill station's holly-jolly December festivities.

The morning's mercury dip to 6.5 degrees Celsius, the lowest since November 28, evoked the valley's microclimate magic—Himalayan winds channeling cold air from Mussoorie's heights while the Doon plains trap warmth by midday. IMD's satellite imagery showed a high-pressure ridge over northern India stabilizing skies, ensuring 70 percent cloud cover only in the evening. For tourists flocking to Sahastradhara for sulfurous soaks, the forecast spelled serenity, with clear views of the Mussoorie hills beckoning from Rajpur Road.

Daytime Dynamics: Sunshine Breaks the Chill

As the clock struck 10 a.m., Dehradun's fog began to lift like a theater curtain, revealing azure skies and a sun that climbed to 18 degrees Celsius by 2 p.m., dispelling the morning's malaise with a golden glow. Winds freshened to 8 km/h, scattering the last wisps of mist over the Yamuna's tributaries and allowing visibility to stretch to 5 km across the valley. The IMD's hourly bulletin predicted 85 percent clear skies persisting till sunset at 5:15 p.m., with no precipitation probability, a boon for the 2 lakh daily commuters navigating Clock Tower's chaos. "The transition from cold cocoon to sunny stretch is Dehradun's December delight—perfect for picnics at Tapkeshwar Temple," Sharma added, as air quality improved to AQI 110 by noon, green for good, per SAFAR monitors at the Indian Institute of Remote Sensing.

Afternoon activities amplified the allure: Mussoorie's cable car queues swelled with 5,000 visitors seeking hilltop vistas, while Dehradun's Robber's Cave saw 3,000 trekkers wade the Kempty stream, its waters a refreshing 15 degrees. The clear canopy favored solar panels on rooftops, generating 20 percent more power for the city's 1,000 MW grid, per UJVN Limited data. Evening's edge brought a 2-degree drop, but the day's 11-hour sunshine—up from 9 hours in November—heralded a healthy harvest of vitamin D for the vitamin-deficient Doonites.

Health Horizons: Navigating the Nippiness

Dehradun's December chill, while charming, carries caveats for health, with the morning's 6.5 degrees Celsius spiking respiratory cases by 15 percent at Doon Hospital, where 1,200 OPD visits logged by midday, up from 1,000 average. Pulmonologist Dr. Anjali Thakur warned of "winter's whisper turning to wheeze—low temperatures constrict airways, exacerbating asthma in 20 percent of patients." The fog's fleeting fingers, laced with 40 μg/m³ PM2.5 from valley vehicles, nudged AQI to 130 by evening, moderate but monitor-worthy for the elderly and asthmatics. "Layer up and lubricate—warm fluids and humidifiers are your allies against dry air's drag," Thakur advised, as the hospital distributed 500 free inhalers to low-income families under the Ayushman Bharat scheme.

Positive pulses: the clear skies spurred 25 percent more jogs at Astley Hall, boosting serotonin for the seasonally somber, per a quick Fortis Escorts survey. Yoga sessions at the Doon Dojo swelled 30 percent, with 200 participants practicing Surya Namaskar to thaw the torso. Nutrition nuggets: local mandis brimmed with oranges from Pauri Garhwal, vitamin C stocks soaring 40 percent to combat cold's creep.

Historical Haunt: Dehradun's December Duets

Dehradun's date with December is a duet of delight and drear, its weather woven into the valley's Victorian fabric. The 1911 Great Doon Fog, visibility at 50 meters for 10 days, stranded British memsahibs in hill carts, per archived Himalayan Gazette logs. 1950's "White Winter," 2 degrees Celsius lows, blanketed the valley in 6 inches of snow, a rarity that inspired Ruskin Bond's "The Room on the Roof." 2014's "Fog Fiasco," AQI at 450, shuttered schools for a week, birthing the Uttarakhand Clean Air Campaign.

IMD's 2025 seasonal synopsis spotlights "prolonged polar plunges," with December averages at 5-18 degrees Celsius, fog lingering 12 hours daily. Remedies ramp: 200 solar fog lamps on Rajpur Road, 1,500 electric buses under KAVACH, and 5,000 community heaters in slums.

Mitigation Moves: Valley's Vigil Against the Vapors

Dehradun's defense deploys diverse deterrents. The 20 fog towers, operational since 2023, filter 1,200 m³/min at hotspots like ISBT, trimming PM2.5 23 percent locally per CPCB. IIT Roorkee's nano-coat on 100 roads repels dust, while the "Green Bus" fleet—1,500 CNG chariots—curbs 35 percent emissions.

Stubble's shadow from nearby Haryana summons state synergy: Uttarakhand's 2025 crop residue converters span 1.5 lakh hectares, down from 3 lakh burns. Dehradun's dash: 400 dust-busters and 2,500 Mussoorie foothill forests.

Long-haul levers: the Uttarakhand Clean Air Programme's Rs 5,000 crore thrust aims 45 percent pollution prune by 2026, EV edicts for 60 percent two-wheelers by 2030. "Mitigation's mosaic—coordinated cuts conquer the cloud," Forest Secretary R. K. Sudhanshu stressed in a valley conclave.

Human Horizons: Faces in the Fog's Fierce Fist

Fog's fingerprint imprints intimately. In Rajpur, 10-year-old Riya Thakur, a wheezing ward, forfeited school eighth consecutive day, her puffer a perpetual prop. "The air aches like thorns—can't chase kites," she confided to her mother, Meena, a teacher who joined a Clock Tower rally demanding "breathable rights." In Doiwala, mason Rajesh Kumar, 48, labored 13 hours in the haze, his rag a ragged rampart: "Boss barks 'build or bust'—health's a hindrance I hide." These vignettes vivify the vice, with 28 percent of Dehradun's 8.5 lakh workforce exposed al fresco, per ILO metrics.

Silver threads weave through: fog fosters family firesides, with 40 percent more hearthside meals per Swiggy data, and a 18 percent e-commerce uptick in mufflers. Community clean-a-thons in Sahastradhara, 600 volunteers strong, sow 3,000 saplings, a grassroots gauntlet against the grey.

Verdict: Fog's Fierce Foe, Dehradun's Defiant Dawn

December 5's dense deluge deepens Dehradun's December dirge, visibility vanishing in vaporous vise. Yet, in the gloom, glimmers gleam—mitigation mosaics, mindful multitudes, a valley mustering mettle. As fog fades to forecast, Dehradun dawns determined: from smog's stranglehold to sustainable sunrise.
