July 17, 2021 6:30 PM |

Monsoon is known for their truant behavior and continue to deviate from the expected lines. No two monsoon seasons are same and the list of  inter seasonal variation grows bigger. The success rate of decoding its nature and performance remains far from  satisfactory as this global phenomenon  keeps testing patience and capacity of collective research across the world.  Onset phase of Indian Sub Continent Monsoon has added yet another feather in its cap of being different from many other seasons. Check out 10 stunning facts of Monsoon 2021 below:

Monsoon arrived over South Andaman Sea with military punctuality on 21st May.  Courtesy cyclone ‘Yaas’ over Bay of Bengal between 23rd-28thMay, the monsoon arrived a day earlier than normal.

After timely onset over mainland, it took a big leap on 06thJune to cover entire Northeast India, Sikkim and Sub Himalayan West Bengal in 24hr.

Monsoon reached Mumbai on 09thJune, a day prior of its normal date and made a resounding onset with 231mm rainfall in24hr.

Monsoon entered Bihar earlier than normal on 11thJune and became the most surplus state in June with 111% excess rainfall.

Monsoon made incremental advance to cover  state of Gujarat between 09th and 19thJune and covered Kutch region well before its normal arrival of 30thJune.

Eastern arm of Monsoon from the Bay of Bengal was stuck from 13thJune till 11thJuly over East Uttar Pradesh, one of the longest haul  in the recent past.

Forecast of early arrival on 15thJune over Delhi failed to make it and it finally reached on 13thJuly with a delay of 2 weeks.

First ever time since 2013, the national capital was covered by monsoon along with the last posts of Jaisalmer and Phalodi in West Rajasthan.

Monsoon 2021 covered 80% of the area in just 10 days.  

Despite delay in reaching North India, Month of June delivered its share and ended with 110% of LPA(long period average)

Maiden low pressure over Bay of Bengal on 11thJune and its subsequent travel over central parts resulted a surplus of 41% rainfall by 20thJune. However, weak monsoon conditions thereafter consumed this surplus and seasonal rainfall became deficit of 8% by 11thJuly.  Courtesy 2nd low pressure area forming on 11thJuly, monsoon became active and the deficiency is now reduced to 5%. Monsoon activity may be subdued for 2 days on 15thand 16thJuly and pick up again to remain good till month end.
