Explanation:

Second statement should read as maximum intensity of Tropical cyclones developing is during the monsoon months (September to November).

Actually there are few tropical cyclones during the southwest monsoon season because southwest monsoon is characterized by the presence of strong westerly winds in the lower troposphere (below 5 km) and very strong easterly winds in the upper troposphere (above 9 km). This results in large vertical wind shear. Strong vertical wind shear inhibits cyclone development.
