Countdown
76 days to race day
The live race-day forecast unlocks 70 days from now, when September 27, 2026 enters the 7-day forecast window — a start-time read for the scheduled 8:45 AM start. Until then, no made-up long-range forecast — the history below is what race morning usually looks like.
Race-morning weather history
Typically cool (8-15C) and world-record friendly (Kipchoge 2018/2022, Assefa 2023); 2021 ran unseasonably warm (~25C). Wyndo tracks what this calendar slot has actually served up at the start hour — temperature, dew point, wind, and rain — including the years when weather canceled or disrupted the race, and reads the live forecast for the start once race week arrives.
The Berlin Marathon moves around the calendar year to year (Sunday in late September (usually the last Sunday; 2025 ran a week earlier)), so there's no fixed slot to compute an honest year-by-year history from — a table built on guessed dates would be wrong, so we don't show one. We're sourcing the real past edition dates by hand; the history lands here when they do.
