India's Wettest Places - Walakkad, Kerala - Series No.1

Whenever people in India ask for wettest / Rainiest places they only know Cherrapunji or Mawsynaram or Agumbe. In these weekly series, you will come to various places which i have identified to be wettest places of India. This series will be published every weekly. If you are fan of Heavy Rains and want to know more than Cherrapunji. Please Read it. Its only a compilation of data from various sources / articles / research materials.

Walakkad which it has crossed 9000 mm rainfall in 5 years of the 12 years available rainfall data is the first in the long series.

 Dhar et al (1978) carried out a study ot the heavy rainfall stations in India. For the purpose of the study, stations with mean annual raintall of 5000 mm were considered as heavy rainfall stations. Of the total 14 stations across India, Only two were from KeraIa namely Neeriamangalam (5880 mm) and Peermade (5000 mm). The rainfall data was available only for less number of years. Over the years the averages have caught up with these two stations and their averages have fallen less than 5000 mm considerably. But rain gauges were installed at many other locations which were experiencing very heavy rains during the monsoons.With the data obtained and analysed, these stations were experiencing more rainfall than Agumbe (7640 mm) called as Cherrapunji of South India. One such place is Silent Valley, where rainfall data is available for Walakkad, Pochipara, Silent Valley, Neelikkal and Sairandhri.
