Goa September '13 Rainfall Analysis - Monsoon Revival!

September 30, marks the end of the official monsoon season, a season which began on June 1!

However this year on September 30th, there is still no sign of the monsoon ending, at least till good part of October. In fact as pointed out in the previous post, there is a revival of sorts of monsoon, which had retreated officially from Rajasthan and NW India. As on date and for the next two three days rains monsoon like rains are expected again in these areas. For a more technical explanation check this video explanation by Rajesh Kapadia in his blog 'vagaries of the weather'

It's no different in Goa!

After the deficient rains in August the trend continued into September and for the first 15 days there was hardly any rains. But then, the rains revived, and with a vigour! The daily September 2013 chart for Margao illustrates the trend as below:


These second half rains have brought the month of September more than the normal rains as recorded for Panaji:


At the beginning of the monsoon season, this post in 'Weather in Goa' Blog had speculated about a few things:

1. Would Valpoi reach 250 inches?
2. Would Panaji (Goa) reach 150 inches?
3. Would Ponda figure in the top 3 places receiving heaviest rainfall?
4. Would Margao get more rains than Panaji?

While Valpoi reached 200 inches on September 30, 250 inches seem out of reach! After the initial excellent rains of July, Panaji struggled to reach 100 inches and did so only due to the late spurt in the rains in September! Sakhali appeared suddenly in IMD's rain centres pushing Ponda to fourth place and YES, Margao finished above Panaji by a large margin!!

So the final seasonal rains are as below:





Thus it appears that it has rained more than 100 inches everywhere in Goa.

Valpoi with the highest and Mormugao with the lowest.

Canacona received the highest rains in September 23.74 inches, followed by Margao at 21.41 inches.



The temperatures recorded during September were as under:

Max Day Temperature : 32.1 C
Min Day Temperature : 27.3 C

Min Night Temperature : 21.6 C
Max Night Temperature : 24.4 C

Average Day Temperature : 30.1 C
Average Night Temperature : 23.5 C

Of course we'll continue to track the rains into October!
