How cold will it get in Delhi?

The Captial experienced the coldest morning of the season with the lowest minimum temperature of 1.4 degrees Celsius recorded at Safdarjung Observatory, according to weather expert Navdeep Sigh Dahiya.

The minimum temperature at Lodhi Road was 1.6 degrees on Monday. It was 2 degrees at the Ridge and 5.3 degrees at the IGI Airport, Palam, the report says.

The weather office had predicted that minimum temperatures are likely to plummet by about 2 degrees celsius over several parts of northwest and central India until Tuesday.

The temperature might go up by Wednesday. On January 18, the temperature will record 4 degrees Celsius, failing to give respite to Delhiites from cold wave conditions, the Met office said.

A severe cold wave is when the minimum temperature dips to 2 degrees Celsius or the departure from the normal limits is by more than 6.4 notches.
