The monsoon season just touched its half way mark on July 31, but the city has already recorded 75% of its annual average, with two months still left.

The average rainfall observed in the city each year is 2,258mm. On Sunday, however, the Santacruz weather station, representative of Mumbai, recorded 1,693.3 mm till 8.30pm - this means the city is just 565mm short of completing it’s annual average performance.

The city recorded 1,693.3mm in June and July, 370mm more than the average rainfall of 1,323mm for the first two months, even though the southwest monsoon set in 10 days late.

Keeping with the trend of heavy rain over the weekend, you could expect heavy to very heavy rain on Monday and Tuesday. Weathermen said three factors are likely to lead to heavy rain.

“Upper air cyclonic circulations over eastern Uttar Pradesh, the Bay of Bengal and a trough over south Gujarat have led to active weather conditions along the western coast,” said Shubhangi Bhute, director, India Meteorological Department (IMD).

“An offshore trough from Maharashtra to Kerala is also drawing a lot of moisture along the Konkan coast and will result in heavy to very heavy rain over the north Konkan areas, including Mumbai.”

On Sunday, the suburbs recorded more rain than south Mumbai. Between 8.30am to 8.30pm, the Santacruz weather station recorded 72.1mm, but Colaba only recorded 22mm. Thane and Navi Mumbai also recorded recurring spells of heavy rain through the day.

However, overnight rain was comparatively less as compared to the two days of heavy rain.

Under the India Meteorological Department’s (IMD) new classification, 15.6mm to 64.4mm of rain is considered ‘moderate’, 64.5mm to 115.5mm is ‘heavy’, 115.6mm to 204.4mm is ‘very heavy’ and more than 204.5mm is ‘extreme’.

On Sunday, day temperatures were a degree Celsius below normal at Colaba, at 28.6 degrees Celsius. Santacruz recorded day temperature almost 3 degrees Celsius below normal at 26.9 degrees Celsius. On the other hand, night temperatures were closer to normal levels. Colaba and Santacruz recorded 25.2 degrees Celsius and 25 degrees Celsius.

Moisture levels were high on Sunday as Santacruz and Colaba recorded 92% and 95% humidity.

Meanwhile, various parts of the state also received heavy rain in the last 24 hours. Harnai received a whopping 127.8 mm of rain, followed by Ratnagiri where 103.7 mm of rainfall was recorded. Other areas to have received good rains include Dahanu 103.6 mm, Bhira 67 mm, Alibag 72.4 mm, and Mahabaleshwar 53.6 mm.
