Pune Weather: Sharp Temperature Rise and Plummeting Humidity Create Unseasonal Heat
The city of Pune has witnessed a significant and rapid increase in daytime temperatures during the first week of March, with meteorological data revealing a dramatic shift from mild conditions to intense heat. This sudden warming has been accompanied by critically low humidity levels, creating challenging weather conditions for residents across the region.
Temperature Data Reveals Rapid Warming Pattern
Weather monitoring stations across Pune recorded substantially elevated maximum temperatures on Saturday. The highest reading of 38.5°C was observed in both Lohegaon and Koregaon Park, while Chinchwad registered 36.8°C, Lavale reached 37.1°C, and Shivajinagar recorded 36.6°C. This represents a significant jump from temperatures recorded just days earlier on February 27, when several stations reported readings of approximately 31–32°C, indicating a rapid warming trend within a remarkably short timeframe.
Humidity Levels Drop to Alarming Lows
Simultaneously, relative humidity plummeted to concerning levels across the city during Saturday afternoon. The lowest humidity reading of approximately 11% was recorded in Lohegaon, while Chinchwad measured 14%, Magarpatta registered 17%, Shivajinagar reached 18%, and Koregaon Park reported around 21%. These exceptionally dry conditions have intensified the perceived heat, making the weather feel substantially warmer than the actual temperature readings would suggest.
The temperature contrast between day and night has also become pronounced, with Pune's minimum temperature recorded at about 15.9°C, creating a day-night temperature differential of nearly 20 degrees. Medical professionals have warned that such significant fluctuations can place considerable stress on the human body, potentially leading to fatigue, dehydration, and increased susceptibility to seasonal illnesses.
Meteorological Explanation for the Sudden Shift
S D Sanap, a scientist at the India Meteorological Department (IMD), explained that the temperature increase is primarily driven by a persistent anti-cyclonic circulation over Gujarat and central India, including Maharashtra. "Temperatures are rising because of the persistence of an anti-cyclonic circulation over Gujarat and the central Indian region, including Maharashtra. This causes subsidence of air and calm winds, which leads to higher daytime temperatures," Sanap stated.
He further clarified that such conditions are typical during India's pre-monsoon season, which encompasses March, April, and May. Sanap noted that maximum temperatures in several areas are currently 2–3 degrees above normal levels, with parts of Vidarbha, including Akola and Amravati, recording departures exceeding 5 degrees from normal—meeting the official criteria for heatwave conditions.
Urban Heat Island Effect Intensifies Local Warming
Urbanization patterns in Pune are exacerbating the heating in specific localities. Areas with dense construction, such as Lohegaon and Koregaon Park, are warming more rapidly due to the urban heat island effect. This phenomenon occurs when concrete structures absorb and retain substantial heat while vegetation—which provides natural cooling—becomes increasingly scarce in developed areas.
Regional Heatwave Conditions and Forecast
While Pune temperatures remain only slightly above normal, neighboring regions are experiencing more severe conditions. According to IMD data, Akola recorded 40.8°C and Amravati reached 40.6°C on Saturday, both nearly 5 degrees above normal and meeting heatwave criteria. Wardha registered 40°C, with several other stations in the Vidarbha region reporting temperatures approaching 39–40°C.
Looking ahead, the IMD forecasts continued clear skies and a gradual temperature increase of 1–3 degrees in maximum temperatures across interior Maharashtra over the coming days. Sanap indicated that "In Madhya Maharashtra, including Pune, temperatures remain close to normal but may increase by another 2–3° in the coming days."
Climatic Context: India's Distinct Seasonal Patterns
Sanap provided important context about India's climatic characteristics, explaining that the country does not experience a clearly defined spring season. "March, April and May are considered the pre-monsoon months in India. Since the country lies in the tropics and receives monsoon rainfall from June to Sept, heat gradually builds up during this period, making the seasonal transition appear sudden," he elaborated.
The scientist further connected the low humidity levels to the same weather pattern, noting that anti-cyclonic circulation typically brings dry air, clear skies, and weak winds—conditions that facilitate stronger heating during daylight hours.
This combination of rising temperatures, plummeting humidity, and significant day-night temperature variations presents a challenging weather scenario for Pune residents as the region transitions toward summer conditions.
