This is a great little resource.   You can click on any major Indian city to see total average yearly rainfall, and when in the year it falls. As you would expect in such a large and geographically varied country there is a huge difference. Rainfall varies from 325 mm in Jodhpur, Rajasthan (near the Thar desert) to 3,595mm in Mangalore, Karnataka (in the south of India on the west coast). India’s rain mostly comes from the monsoon and the effect is very clear in the accompanying graphs.

2012 was the second wettest year in the UK since records began and the wettest summer. But 1,330 mm of rain in the year is just one third of Mangalore’s rainfall and comes nowhere near the village of Mawsynram in North East India near Shillong which has an average rainfall of 11,872mm, officially the second wettest inhabited place on earth. As I write this newsletter in a cold and wet March I thought a couple of clips of the monsoon in Delhi  (due in July) would cheer us all up
