During the rainy season of 2013, the total rainfall for parts of Danang was slightly higher than the average of many years, heavy rainfall mainly concentrated September, October and November. In 2013, there were a number of days with intense rainfall, such as date August 19th with the rainfall from 200 - 360mm, date October 15th with the rainfall from 150 - 350mm, date November 16th with the rainfall from 280-450mm. However, at the end of the rainy season, the rainfall in Danang and the surrounding areas was deficient compared with the same period of previous years. Especially, there was no rain in Danang from January 30th to March 14th.
 
In late 2013 and early 2014, the northeast monsoon was stronger than the average of previous years, but the intensity was following the rule. However, from December 2013 to January 2014, many northeast monsoons occurred continuously, affecting the weather and distracting fishermen in Danang. During the flood season in 2013, there were 7 floods in most rivers of the Central Region, including 3 small floods and 4 large floods. In Danang, the flood peaked in mid-November, exceeding level 3 in Cam Le.

In the early dry season of 2014, the flows of Vu Gia and other rivers in Danang declined sharply, the average flow of Cai River in Thanh My only reached 6% of annual average flow. As a result, downstream salinity intrusion was more intense than the average of the same period last years.
