The season started on 20 July 2018 and concluded on 19 May 2019.[8] It is the second Ekstraklasa season to use VAR. After the 20th matchday the league went on a winter break between 23 December 2018 and 8 February 2019. The regular season was played as a round-robin tournament. A total of 16 teams participated, 14 of which competed in the league during the 2017–18 season, while the remaining two were promoted from the 2017–18 I liga. The fixtures were announced on 22 March 2018.[8]
Each team played a total of 30 matches, half at home and half away. After the 30th round (in the beginning of April 2019), the league was split into two groups: championship round (top eight teams) and relegation round (bottom eight teams). Each team played 7 more games (teams ranked 1 to 4 and 9 to 12 played four times at home). Therefore, each team played a total of 37 matches. The team at the top of the Championship round won the league title. The two teams at the bottom of the Relegation round were relegated to 2019–20 I liga. This was the sixth season to take place since the new playoff structure has been introduced.
Sixteen teams will compete in the league – the top fourteen teams from the previous season, as well as two teams promoted from the I liga. Miedź Legnica were promoted to the Ekstraklasa for the first time.[9]Zagłębie Sosnowiec will make a return to the Ekstraklasa for the first time since 2008.[10]
