May 2015 has been the most uncomfortable in recent years in Calcutta as both of the two parameters - temperature or humidity were high compared to those in the same period in 2014 and 2013, when at least one of the two parameters - temperature or humidity - was relatively low. But unfortunately, this year the whole month of May was about 10 notches more humid than last May and a degree-and-a-half hotter than the year before. So, this May was a horrible month to the Calcuttans.
