Summer is followed by South West Monsoon that starts pouring in the month of June and continues till September. Though there is no distinct difference in the climatic conditions only with the increase in humidity .Sometimes the downpour may continue persistently even for two or three days. In this period, maximum rainfall is received by Vaithiri-Kuttiyadi range in Malabar and Peerumedu in Idukki. The rainfall is comparatively much less in the Lakshadweep islands. In the northern regions of Kerala, the rainfall is around 80% and in the southern regions the rainfall ranges from 40-50%. Actually the existence of the Western Ghats on the eastern side of the state of Kerala creates a barrier across the path of the southwest monsoon. This resulted in the creation of a significant climatic variation with abundant rainfall on the windward side and a dry belt on the lee eastern side.
The North East Monsoon begins in the month of October and stops at the end of December.
With the arrival of winter there is certain drop in the temperature and you can feel a slight chill due to the cold wind. Winter is truly enjoyable in Kerala and lasts from from November to January or February. Occasionally very little rainfall accompanied by thunder and lightning takes place in the northern region of the state. Highest rainfall is received by Kottayam during this winter season.
