As the monsoon seems delayed by a few days, the nights in the city and adjoining areas have started to get warmer. Meteorologists have correlated this to the weather system developing in the Arabian Sea. The sweltering and stuffy nights might continue until the monsoon sets in, meteorologists have said.

As per the India Meteorological Department (IMD) and Vagaries of Weather, a popular private weather blog, on the night of June 4, the minimum temperature recorded at the Santacruz observatory was 29.5°c (highest this season). A minimum temperature of 28.8°c was recorded at the Colaba observatory.
