Temperature was at around 41’C yesterday at Mylapore and it was the hottest day so far, this year. The sea breeze which usually sets in around 11:30 a.m. set in at about 12:45 p.m. and this could have caused temperatures to shoot up, says a release by the meteorological department. This could be the case for this entire week. The heat, along with the strike in public services, made it a tough day for many commuters.
