According to the James Hutton Institute data, the wettest single day last month was October 3, when 62mm of rain poured down.
That marks the highest daily rainfall since September 3 2009, when 65.9mm was recorded.
Since 1954, there have only been four months which was more rain: August 2004, December 1978, January 2015 and November 1984.
Those months faced 256.3mm, 215.6mm, 191.7mm and 180.3mm of rain respectively.
Other parts of the country also faced a soaking, with Storm Barbara battering the UK.
As well as being wet, October was also among the darkest months on record in the Dundee area.
Last month was the 19th dullest since 1954, with below average daily hours of sunlight.
The temperatures were warmer than usual for the time of year, however, when compared to a 30-year average.
