MUMBAI: The city experienced high overnight temperatures between Saturday night and Sunday morning owing to an overnight cloudy sky.
A spike in mercury levels was recorded, especially in south Mumbai as the minimum temperature shot up by 2.2 degrees Celsius above normal with the Colaba weather station recording 29.8 degrees Celsius. The weather station at Santacruz also recorded night temperatures 1.5 degrees Celsius above normal at 29 degrees Celsius.
Weathermen on Sunday said the city can expect a partly cloudy sky during the day on Monday and light rain accompanied by thundershowers by the evening.
“Moisture levels are high along the coast and this is leading to cloud formation. The clouds are trapping the heat from radiating outside during the night, which is leading to a high temperature. However, we expect this phenomenon will lead to light rain during the coming week,” said VK Rajeev, director, western region, India Meteorological Department.
Day temperatures at both south Mumbai and the suburbs were also almost 2 degrees Celsius above normal. Between 5.30pm Saturday and 5.30pm Sunday, Colaba recorded 35.7 degrees Celsius, 1.8 degrees Celsius above normal while 35 degrees Celsius was recorded at Santacruz, which was 1.5 degrees Celsius above normal.
Meanwhile, high temperatures, moisture accompanied by fast moving winds dispersed pollutants from the city on Sunday. Mumbai recorded an air quality index (AQI) of 97, falling under the ‘good’ category.
Pollution levels are expected to increase on Monday as an AQI level of 102 (moderate) was predicted by the System of Air Quality Weather Forecasting and Research.
