Why Delhi may see a dry spell Experts said the changing rainfall pattern is linked to the monsoon axis not remaining over Delhi.
“It is still fluctuating, and is mainly remaining at the Himalaya foothills. It travels slightly southwards during the night, and thus we saw some rain during the nights on the weekend. However, from Tuesday onwards, the city’s weather is likely to be completely dry, as the axis will move completely to the foothills. Due to this, we are expecting dry weather to remain till the end of August, and even during early September,” said amateur meteorologist Navdeep Dahiya.
