Now, with the anticyclone well placed over the North and the west, it seems the monsoon has finally moved out and widhrawn from the peninsular, at least from above the 15°N. I say it seems as the IMD has not officially widhrawn the monsoon from below the 20°N. till 12th October. From my personal jottings, I read that one of the later dates of monsoon widhrawal for Mumbai, in the recent past was 17th October in 1983.

For the month of October, Mumbai (Colaba) has had 246mm of rain and Santacruz 200mm as on date. However, for the rcords, the wettest October for Colaba was in 1917, when the month had 507 mm.

With the monsoon now over from the major portion of North and central India, the temperatures are rising due to the absence of W.D. and cooler winds from the North West. Temperatures in most parts of India, except the South, are 3-5°c above normal. See map.

Also, most of the sub continent is quite (after4 months), and will remain so for a week at least, before the winter rains start in the south. There may be some precipitation in the extreme north due to the W.D. now over the middle east.
