What this is

Say what a good day is to you — how warm, how dry, how still — and this replays the record against it: several years of daily readings from — weather stations in — countries.

A day counts where every switched-on term holds. The map shows where that happened, the timeline when, and the standings who gets the most of it. Land drawn grey has no station within 200 miles.
