See Better, Breathe Fresher: Clean Air Paints Sky Blue For Second Day
New Delhi: Delhiites saw clear blue skies on Thursday as air quality remained in the 'satisfactory' category for the second straight day. The AQI stood at 89, compared to 81 on Wednesday, when the city had recorded its cleanest air in 261 days. Although Delhi did not receive any rain between 8.30am and 5.30pm, the Met department issued a 'yellow' alert for light to very light rain accompanied by a thunderstorm and gusty winds up to 40kmph from Fridayto Monday. Thursday was this year's fourth 'satisfactory' day. Delhi, however, is yet to experience a 'good' day so far in 2025. The last 'good' air day was Sept 10, 2023, when the AQI was at 45 due to rains and the restrictions imposed for the G20 Summit. In March, Delhi witnessed two consecutive 'satisfactory' air days, on March 15 and 16, with AQI readings of 85 and 99, respectively. CPCB defines a 'good' air day as one when AQI is below 51, while a 'satisfactory' level has an AQI reading of 51-100. The air quality is predicted to deteriorate to the 'moderate' category on Friday but may again stay in the 'satisfactory' range on Saturday and Sunday, according to the Air Quality Early Warning System for Delhi, which is the forecasting body under the Union ministry of earth sciences. "Due to easterly winds and the presence of moisture, rain is likely to happen this week. As rain and gusty winds are expected over the next few days, it will help in settling down the pollutants," said an official. The maximum temperature on Thursday was recorded at 36.4 degrees Celsius, two degrees below normal, compared to Wednesday's 34.2 degrees Celsius. The minimum temperature settled at 27.2 degrees Celsius. The maximum temperature on Friday is likely to stay between 36-38 degrees Celsius while the minimum is predicted to stay around 27-29 degrees Celsius. The southwest monsoon is also progressing in north-west India. The normal date for the onset of the southwest monsoon over Delhi is June 27, but IMD has not specified when it is expected to reach the city. "Conditions are favourable for further advance of southwest monsoon over the remaining parts of North Arabian Sea and MP; some more parts of Rajasthan and UP; some parts of Uttarakhand, Himachal Pradesh, Jammu-Kashmir-Ladakh-Gilgit-Baltistan-Muzaffarabad during the next two-three days," said IMD. Conditions are also becoming favourable for further advance of the southwest monsoon over some parts of Punjab and Haryana during the subsequent two-three days, it added.

Delhi offers no respite after sunset, national capital's 3rd hot night in a row
It's not just the blazing sun but the stifling nights that are wearing people down in the Capital. On Friday, the minimum temperature rose to 31°C—marking the third consecutive night of oppressive heat and offering little relief after the scorching days. While the daytime temperature dipped slightly on Thursday, any respite was short-lived, as the nights have only grown warmer through the week, intensifying cumulative heat stress and leaving residents with no chance to cool off. Also Read: IMD warns of heat wave till June 14 for northwest The India Meteorological Department (IMD) said sustained high night-time temperatures can worsen health outcomes, particularly among the elderly, children, and people with chronic illnesses. 'Humidity levels remain high, and night-time warmth is adding to the overall stress,' an IMD official said. Daytime heat, though marginally lower on Friday, was still intense. The maximum temperature at Safdarjung, the city's base station, dropped to 41.2°C on Friday—1.3°C above normal and down from 43.9°C on Thursday. The city's heat index or 'real feel' also saw a modest decline, touching 51.5°C at 2.30pm compared to over 53°C the day before.

Still, the IMD issued an orange alert for Friday, upgrading its earlier yellow alert, and warned of hot and humid conditions through the day, followed by potential thunderstorm activity at night. The alert forecast very light to light rain, accompanied by lightning and gusty winds reaching 40-50 kmph, and occasionally touching 60 kmph. Also Read: Delhi heat wave: IMD's orange alert on as city's temperature 'feels like' almost 50 deg C IMD scientist Krishna Mishra said the weather shift was triggered by the weakening of a mid-level ridge and a low-level anti-cyclone, which have now been replaced by a trough in easterlies. 'This, combined with a western disturbance, is behind the slight dip in day temperatures and the expected weather activity over the weekend,' he said. The department expects light rain with thunderstorms and gusty winds to continue over the weekend and into the first half of next week. Maximum temperatures are likely to hover between 39-41°C on Saturday and may dip further. The minimum is expected to range from 28-30°C and gradually decline in the coming days. Meanwhile, Delhi's air quality remained in the 'moderate' category, with the 24-hour average AQI recorded at 187 on Friday, slightly lower than Thursday's 195. According to the Air Quality Early Warning System (AQEWS), this trend is likely to continue through the weekend and into early next week. 'The air quality is likely to be in the moderate category from Saturday to Monday. The outlook for the subsequent six days is that the air quality is likely to be in the moderate category,' the AQEWS bulletin said on Friday evening.

At 43.8°C, Capital swelters
New Delhi: If Monday turned up the heat, Tuesday cranked it higher. It was so hot in Delhi on Tuesday that the mercury breached Monday's record to mark the season's hottest day, with heatwave conditions reported in parts of the city. The India Meteorological Department (IMD) issued an orange alert, warning of potentially adverse weather. Safdarjung, Delhi's base observatory, recorded a maximum of 43.8°C — 3.9°C above normal and the highest the season so far, eclipsing Monday's 43.4°C. Before that, the season's peak was 42.3°C, logged on May 16. Heatwave conditions were reported from isolated areas such as Lodhi Road, Ridge and Ayanagar, with Ayanagar topping the charts at 45.5°C — its second consecutive day above the 45°C mark. IMD declares a heatwave when the maximum exceeds 40°C with a departure of at least 4.5°C from normal, or breaches 45°C outright. Though slightly better than Monday, the 'real feel' temperature remained higher than the actual maximum. Factoring in humidity, which swung between 24% and 48%, the heat index peaked at 47.1°C by mid-afternoon. The wet-bulb temperature — a key indicator of heat stress — was 26.2°C at Safdarjung, lower than Monday's 28.17°C but still close to thresholds that increase the risk of heatstroke. An orange alert has been issued for Wednesday as well. 'Heatwave conditions are likely to persist on Wednesday, with dust-raising winds of 20–30 km/hour. Gradual respite is expected over northwest India from Friday,' said an IMD scientist, asking not to be named. A yellow alert has been issued for Friday, with forecasts of very light to light rain, along with thunderstorms, lightning, and gusty winds — all expected to bring down the temperatures. The minimum temperature remained steady, recorded at 27.8°C — nearly unchanged from Monday's 27.6°C. IMD has forecast further rise in both minimum and maximum temperatures on Wednesday, with the maximum temperature expected to hover between 44°C and 46°C. The minimum, too, is expected to rise on Wednesday and stay in the range of 28-30°C. This run of heatwave days has caught the city off guard. The month of May saw unusually high rainfall that kept temperatures in check, with no heatwave days — a sharp contrast to six in May last year. April, however, had recorded three heatwave days this year, compared to none in 2024. Air quality in the Capital remained in the 'poor' category. The air quality index (AQI) stood at 215 (poor) at 4pm Tuesday, according to the Central Pollution Control Board's daily bulletin. This was slightly better than Monday's 235 (poor), but worse than Sunday's 198, which fell in the 'moderate' range. Forecasts by the Air Quality Early Warning System (AQEWS) suggest the AQI will remain 'poor' through Thursday, before improving to 'moderate' by Friday. 'The air quality is likely to be in the poor category from Wednesday to Thursday. The air quality is likely to be in the moderate category on Friday. Ozone will become predominant at some stations in the afternoon for a few hours owing to clear sky and strong sunlight. The outlook for the subsequent six days is that the air quality is likely to be in the moderate to poor category,' the AQEWS bulletin said on Tuesday evening. With both mercury and pollution levels running high, residents have been advised to stay indoors during peak afternoon hours, stay hydrated, and avoid strenuous activity — precautions that could prove crucial as the Capital braces for more extreme days ahead.
