It was a separate municipality but became administratively a part of Havířov in 1960. It has a population of 901 (2020). The village lies in the historical region of Cieszyn Silesia.
The name is of topographic origin, supposedly derived from an older name of a hypothetical river or stream Sucha, literally dry, therefore disappearing. The supplementary adjective Dolní (German: Nieder, Polish: Dolna) means Lower denoting its lower location in comparison to sister settlements: Prostřední Suchá (Middle) and Horní Suchá (Upper).
The village was first mentioned in a Latin document of Diocese of Wrocław called Liber fundationis episcopatus Vratislaviensis from around 1305 as item in Sucha utraque. It meant that there were two villages of that name (utraque meaning both in Latin), the other being Horní Suchá.
Politically the village belonged initially to the Duchy of Teschen, formed in 1290 in the process of feudal fragmentation of Poland and was ruled by a local branch of Silesian Piast dynasty. In 1327 the duchy became a fee of the Kingdom of Bohemia, which after 1526 became a part of the Habsburg Monarchy.
After the Revolutions of 1848 in the Austrian Empire, a modern municipal division was introduced in the re-established Austrian Silesia. The village as a municipality was subscribed at least since 1880 to political district and legal district of Freistadt.
According to the censuses conducted in 1880, 1890, 1900 and 1910 the population of the municipality grew from 944 in 1880 to 2,237 in 1910. In terms of the dominant language spoken colloquially the situation was shifting through the censuses.

There was a coal mine in the village - Dukla Mine. It was founded in 1905 as Kaiser Franz Joseph Schacht. The mining operations began in 1911-1912.
