In Patna, as in most of Bihar, the summer temperatures rise very high as the hot tropical sun beats down with all its intensity coupled with a heat wave which though is not as severe as say in Delhi. The city, being near four large rivers, experiences a rather high humidity throughout the year.

The summer begins in April and peaks in June/July with the temperature soaring up to 46° C till the moisture laiden monsoon wind bring some much-needed relief to the parched fields. The rains last through August & September and continue into early October. The northern Indian winters bring bitter cold nights and sunny days to Patna from November to February till the arrival of the spring that brings the weather to a full cycle.

The local almanac divides the year into six seasons of roughly two months each. Apart from the usual four seasons: Summer, Monsoon, Winter and Spring, you may add mild winter between Monsoon and Winter and Mild summer just before the onslaught of the severe north Indian summer.
