Chandigarh, June 5 -- Though June is one of the hottest months in the city, this year, it has begun on an unusually cool note, thanks to rain and thunderstorms over the past three nights. Showers in the early hours of Wednesday brought the minimum temperatures down to 18.2degC, 8.1degC below normal, at the airport station. At the IMD station in Sector 39, where 1.7 mm rain was recorded, the minimum was slightly higher at 21.7degC but still 4.6degC below normal. While last year, the city had seen record-breaking temperatures in the month of June, this year, it has recorded 13.9 mm rain in just four days, which is more than the total rainfall recorded through the month last year (11.9 mm). The total rainfall from June 1 to 4 is 71.6% above normal. The normal rain for the month of June is 155.5 mm. In 2023, 142.9 mm rain was recorded during the whole month. Even May was relatively cool this year with not a single day with heatwave conditions. Last year, the maximum temperature had shot up to 45.6degC on June 14, the highest in over 70 years. Explaining the anomaly, India Meteorological Department (IMD) Chandigarh director Surender Paul said a combination of Western Disturbances (WDs) and moisture from systems over the Bay of Bengal and Arabian Sea have led to frequent showers. "There have been frequent rain spells in the city since the second half of May which we are seeing in June as well," he said. But the relief is set to be short-lived as temperatures are expected to soar past 40degC by the end of this week, IMD officials said. With no active Western Disturbances expected in the coming days, Paul said a gradual increase in temperature can be expected. Showers can be expected on Thursday, but temperatures are set to rise from Friday, and reach up to 41degC by Sunday. The minimum temperatures could also climb by seven notches by Monday. The maximum temperature dropped from 36.2degC on Tuesday to 34.5degC on Wednesday, which is 4.7degC below normal. Over the next three days, the maximum temperatures are expected to hover between 35degC and 39degC, while the minimum will stay between 23degC and 26degC....
