The financial capital is known for typical Mumbai monsoon rains during the season. Incessant rains bring the vibrant city to a grinding halt on more than one occasion during August. The 2nd rainiest month of the season, August has anormal rainfall of 560.8mm. July tops the list with an average of 919.9mm. November to April literally observe moratorium with insignificant or negligible rains.
This season kick started for the capital city. Month of June and July exceeded the normal with good margin, more so for July. The city had a soaking spell during closing days of July and has gone silent thereafter. The pattern so far, is somewhat similar to August 2018 but that season had picked up later. Whereas there are dim hopes of the monsoon activity reviving soon.
Largely, there are two monsoon drivers for the coastal and rainiest city of Mumbai. First one is the off shore trough, extending all along the Western Ghats and a semi permanent feature for the season. The other one being fresh monsoon systems emerging over the Bay of Bengal, accelerating monsoon stream over the Arabian Sea and heading towards Konkan coast. Third feature, though not very common and also infrequent, is the mid tropospheric cyclonic circulation (MTC) evolving over Gujarat, North Konkan and southwest Madhya Pradesh. None of these features are likely, not even a hint, over the next 10 days.
Monsoon rains will remain absolutely light and fleeting for Mumbai. Mostly single digit rainfall is expected in 24 hours. One odd shower could be moderate between 16th and 18thAug. Rains will turn light and patchy, once again till 24thAug 2023.
