Sundargarh, Odisha — Rourkela recorded an all-time low of 3.6°C on January 9, 2026, amid a severe cold wave sweeping across Odisha. The India Meteorological Department (IMD) confirmed the reading, which has sent shockwaves through the industrial town, known for its steel plant and tropical climate.

Background Rourkela, typically characterised by its semi-arid climate, has historically experienced winter temperatures ranging between 12°C and 22°C. The previous lowest temperature, 6.8°C, was recorded in 1982, making the recent 3.6°C drop a historic anomaly. Meteorologists attribute this extreme cold to a combination of prolonged cloudless nights, low humidity, and a high-pressure system over the Bay of Bengal, which has intensified winter conditions across eastern India.

Sequence of Events The temperature began plummeting in late December 2025, with daytime highs dipping below 15°C. On January 9, Rourkela’s mercury fell to 3.6°C, shattering historical records. The IMD confirmed the reading after cross-verifying data from three regional stations. Officials noted that wind speeds of 15-20 km/h and humidity levels around 45% exacerbated the chill, making the effective temperature feel even colder.

Community Impact The cold wave has disrupted daily life, with 120 families in Rourkela’s low-income settlements reported to be without electricity due to frozen transformers. Hospitals have seen a surge in patients with frostbite and respiratory infections, while schools remained closed for three consecutive days. The Sundargarh administration distributed 500 emergency blankets and opened two temporary shelters, but activists criticised the response as insufficient. “The elderly and street vendors are the most vulnerable,” said Dr. Anjali Meher, a local physician.

Local Significance As Odisha’s second-largest industrial hub, Rourkela’s economy has suffered production delays at the Steel Plant of India, with workers citing frozen machinery. Farmers in adjoining villages have begun covering crops to prevent frost damage, while local markets report a 30% spike in demand for woollen clothing. The cold wave has also raised concerns about water supply, as hand pumps and borewells in remote areas have started freezing.

What Happens Next The IMD predicts temperatures will remain below 10°C until January 15, with a gradual rise expected thereafter. Authorities have been ordered to inspect infrastructure for ice-related damage, and the state government has allocated ₹2 crore for relief efforts. Residents are advised to stay indoors and use alternative heating sources cautiously. “This is a wake-up call for climate adaptation,” said Sundargarh Collector Rajesh Kumar. The district administration has pledged to review its disaster management protocols in light of the crisis.
