The Regional Meteorological Centre, Chennai, says the mercury will creep up considerably in the days to come. The maximum day temperature will hit anywhere between 31 deg C and 35 deg C, while the nights will be about 10 degrees cooler. While the good news is that evenings will be 8 to 10 degrees cooler, this still may not be cool enough for residents to be comfortable without turning on the fan fully or reaching for the AC remote.
