PUNE: A large part of the state, including Madhya Maharashtra, will experience colder winter nights till February next year. In contrast, higher-than-normal minimum temperatures are expected in a good part of north India during the same period, India Meteorological Department (IMD) director general Mrutyunjay Mohapatra told TOI on Friday.
Mohapatra’s inference is based on IMD’s December 2022- February 2023 seasonal outlook. “This could mean below-normal night temperatures during the winter, with a higher probability of increased frequency of cold waves in central parts of Maharashtra,” he said.

The state’s interiors are generally more prone to lower night temperatures during the winter. Some of these regions, including Marathwada, Vidarbha and Madhya Maharashtra, are also part of India’s “core cold wave zone”, which also include the northern parts of the country, especially the hilly regions and the adjoining plain areas.
Mohapatra said though the exact reason for colder winter nights for Maharashtra this season cannot be ascertained as of now, one could only speculate.
“It could be possible that western disturbances, which bring winter rainfall and snow in north India, could be fewer this winter, reducing the frequency of colder nights in parts of north India. Having said that, Maharashtra could be affected with instances of cold and dry winds blowing from colder regions of north India, causing lower-than-normal night temperature. But only the day-to-day weather conditions in the coming days would help ascertain the actual causes,” he said.
The seasonal forecast for December 2022 to February 2023 showed that most parts of Maharashtra have 35-45% probability of colder-than-normal night temperatures, except Konkan.
At the same time, several parts of Maharashtra have higher probability of near-normal day temperatures this winter, except a few parts in Konkan and east Maharashtra, where the maximum temperatures could be above normal.
Another IMD official told TOI, “Generally in La Nina years, winter temperatures are below normal. But this winter is likely to bring above-normal night temperatures in parts of north India. Prevailing La Nina conditions could be one of the reasons for lower-than-normal night temperatures expected in Maharashtra this winter because a few regions from the ‘Core Cold Wave Zone’ are also in the state.”
Recent studies have shown that anomalous northerlies in the lower and mid tropospheric levels can be seen over the “core cold wave zone” during a La Nina event in general. This indicates above-normal incursion of dry and cold air from the north, leading to unusual cooling of the boundary layer and more cold waves during La Nina phases.
The official said another reason for the phenomenon could be that Maharashtra might have more instances of clearer day and night skies this season, which could cause lower night temperatures but near-normal to higher-than-average day temperatures in some parts.
The minimum temperature in Shivajinagar was below normal by 1.5°, at 11.1°C. In Lohegaon, the minimum temperature for the day stood at 14.1°C, which was 1.1° above normal. As per the Met department forecast, the maximum and minimum temperatures in the city are expected to be 31°C and 12°C, respectively.
