Kerala faces the South-West Monsoon which starts by the end of May and brings heavy rain. The climate is cooled. Uttar Pradesh on the other hand lies to the north, in the interior. It will get the rain from the Bay of Bengal branch of the South-West Monsoon which will reach there by the end of June or beginning July. This rain will also be much less as the winds continue dropping their moisture on the way. The plains are very hot in the month of June.
