September 2026 has been one of the busier stretches on the Counter-Strike 2 calendar, with several S-Tier events overlapping alongside A-, B- and C-Tier competitions across Europe, Asia, the Americas and Oceania.
According to a calendar overview, the top of the schedule this month has run through events including BLAST Open Porto, FISSURE Playground 3, StarLadder StarSeries Fall and Logitech G Play Connect, with StarSeries Fall closing out the S-Tier run around the 20th. Some regional B-Tier series — such as CCT South America and CCT Europe editions — spill past month's end into October.
A practical reminder for anyone tracking results: calendars shift. Several C-Tier entries this month were cancelled or rescheduled, so it's worth confirming an event is actually live before planning around it. Our match pages reflect the schedule as pulled from tournament data, updated regularly.
