Mumbai continues to reel under warm and sultry conditions with high humidity levels, throughout the day. After the withdrawal of the southwest monsoon, Mumbai undergoes a reversal of wind pattern with land breeze becoming dominant in the night and morning hours. Sea breeze sets in, anytime after 12 p.m, raising the humidity level and increasing the discomfort in the afternoon. The evening breeze acts as a soother, more so, right along the coast and a bit less, away from it.
Mumbai has an extended dry weather period from October to March. It gets interrupted only by some post-monsoon freak storm in the Arabian Sea, coming closer to the Konkan Coastline. After the retreat of the monsoon, the months of October and November find similarities. Day temperatures continue to hover around 33°-34°C, during both these months. Yes, the night temperature does see a drop from 24°-25°C in October to about 21°C in November.
Weather conditions over Mumbai gets dictated by the pattern over the plains of North India and more so, Punjab and Rajasthan. After the establishment of a winter anticyclone over Rajasthan in November, the cool winds reach as far as, North Gujarat, North Madhya Maharashtra and Konkan, including Mumbai. This pattern is yet in the making and therefore, little delay is likely.
Even the plains of North India are witnessing unusually warm days and nights. There is no active western disturbance, even for the higher ranges of the mountains. Without the snowfall in the higher areas of Jammu & Kashmir and Himachal Pradesh, the winter chill does not trickle down to the plains. The cascading effect of this cold sweep only reaches further over parts of Gujarat and Maharashtra. With likely delay expected for the typical wintry weather over North India, the Konkan Coast and Mumbai will have to bear with an extended spell of warm and sultry weather.
