Each cell is that destination's own verdict for the month — sweet spot, ok or avoid — with its typical daily high, from the same ten years of climate readings its page is built from. A dot marks a busy month. The last row counts the sweet spots, and the best months are marked.
Between the stops

Distances are great-circle and the flight time is estimated from them. A road, train or bus line is listed only where it was measured — flights from AeroDataBox, roads from OpenRouteService, trains and buses from public timetables via Transitous — and none of it is a fare; the searches on each stop's page are where prices live.
Every verdict here is the destination's own: ten years of climate readings, the public holidays that crowd it, and what the flight costs. Nothing is said about East Asian cities as a whole that was not first measured at each place in it.
