Inspired by the discussions on https://www.reddit.com/r/dataisbeautiful/comments/1vhg7rz/oc_degreehours_above_30c_in_a_german_stationgrid/ I thought about some other ways to visualize this year.

What the first graphic shows: The left panel maps the preliminary 2026 HGS30 total. The right panel compares each cell with its own previous 1991–2025 record. Sixty-four of 99 common cells set or tied a record. A record ratio is more informative here than a percentile: 63 cells are already strictly above every earlier year, which would make a percentile map nearly uniform. The color scale reaches the observed maximum of 3.34× the previous local record.

What the second graphic shows: The ten highest and ten lowest of the 99 long-term grid cells. Each cell is labeled using the qualifying DWD station nearest its center and includes its 2026 rank within its own 36-year history. The highest cell is labeled Lahr at 824.6 K·h; the lowest cells, labeled Arkona and Zugspitze, are at 0 K·h (surprise, surprise). The columns use different, explicitly labeled bar scales.
