Tracking The Monsoon
Is the country having a normal monsoon? A bad one? Or are we getting too much rain? This graphic keeps a daily track of how the monsoon has been for the country, its various regions and states.
Key to gauging the health of the monsoon is the long-period average (LPA), crudely the average rainfall an area has received over 50 years from 1971 to 2020.
If the rainfall a region has received is 0 to 80% of this LPA, it is considered deficient. If it's 81 to 119% of the LPA, it is normal. And if it's 120% or over, it is excess.
Also available below is an option to check how the rainfall for an area compares to the LPA for the whole season. This allows us to essentially understand how far the monsoon has progressed. (Click 'Whole Season' below to learn more.)
