Delhi weather: Delhi on Wednesday recorded a minimum temperature of 28.7 degrees Celsius, 5.4 degrees above normal, the weather office said.
The India Meteorological Department (IMD) forecasted a generally cloudy sky with light rain. The relative humidity at 8.30 am was 74 per cent.
The maximum temperature is expected to settle at 34 degrees Celsius, the IMD said. The air quality was recorded in the moderate category as the Air Quality Index (AQI) at 9 am stood at 107.
According to the Central Pollution Control Board (CPCB), an AQI between zero and 50 is considered ‘good’, 51 and 100 ‘satisfactory’, 101 and 200 ‘moderate’, 201 and 300 ‘poor’, 301 and 400 ‘very poor’, and 401 and 500 ‘severe’.

Boating relaunch at Purana Qila draws huge crowds
Boating at Delhi’s 16th-century Purana Qila has made a comeback after nearly a decade, and the response has been overwhelming. The facility, revived by the Archaeological Survey of India (ASI) and managed by the Sabhyata Foundation of the Dalmia group, has already tripled footfall at the monument, officials said. “Due to the closure of the zoo, footfall increased. Every day, 2,500–3,000 people visit. Before the zoo closure, we would get around 800–1,200 or sometimes 1,500 on weekends. Now it touches 2,500 or around 3,000 on weekends,” said an ASI official.
Researchers, led by those at the Indian Institute of Technology (IIT) Delhi, have developed an AI tool that can predict performance of HVAC filters and help design smarter ones, essential for improving indoor air quality. The COVID-19 pandemic, which necessitated people to stay at home, brought to fore an urgent need to improve indoor air quality, especially through better air filtration in heating, ventilation, and air-conditioning (HVAC) systems, said the team including researchers from Sweden. The challenge is that filters trapping more harmful particles often block airflow, making systems less efficient and more energy hungry, they said.
