How to read these numbers

Season window: from the Monday after the Sunday of the Dead to 22 December, as described in Wikipedia (de): Weihnachtsmarkt; we applied this rule to every season 1991–2025 as a climate window — past opening dates were not checked year by year.
ERA5 is a reanalysis on a 0.25° grid (about 25 km): it counts slightly more light-rain days than nearby weather stations (by about 5–7 percentage points) and gives daytime highs about 1–2.5 °C below station readings, so real hot days were hotter than shown here.
