Slot climatology, honestly framed: each row is the weather at this race's usual calendar slot and start hour (ERA5 reanalysis at the start line) — including years when the edition was canceled or moved, because what the slot serves up is exactly the question. A computed slot date is not a claim the race ran that day.
