You have asked to explain these,as you call, weather changes in Mumbai.
Let me tell you ,in my 55 years of Mumbai weather observations, I have extremes such as
Heavy December rains in 1966, November thundershowers in 1976,unlikely heat in first week of March ,40c,in 1980, that also first 40c in India, hails in March ( please check year in Extreme Blog), torrential 1day rain of 580 mms at colaba in 1974, Low of 11c and 7c at calabash and scruz many years ago.
Many more in Extreme Blog.
Weather changes occur due to cyclic climate variations.
Yes,for sure,there is a change due to urbanization.
Changes are restricted to urban islands.
Accept these variations,they are everywhere and cyclic.
If in doubt, ask.
It may be unusual,but has happened before.
People's memory is short!
Thank you Rajesh sir for your detailed reply. I was not knowing that.
Agreed that such extreme may happen once a while but my question was is there gradual change in Mumbai climate?
Earlier days rain used to start in early june, Diwali used to be cooler followed by winter till Holi. Summer was not so extreme though humid.
But last few years specially 2021 cold was shorter due to January rains. Heat started in mid February, mid may cyclone and delayed rain. Fortunately monsoon was good. Now November humid warm weather with rain.
Does it indicates weather change in Mumbai? Or this is one of those extreme years.
Even Maharashtra interior experience more rain than earlier years?
When we were kids we use to see cool night temperatures after diwali.we use to do camp fire at night during december. May be city was small and more open spaces less vehicles and more trees at that time in suburbs were the reason to feel cool..Now it's all concrete..
