Weekly note

Boston or Mexico City?

3,665 km apart, in United States and Mexico. Each is scored month by month on the same ten years of climate readings, the public holidays that crowd it, and what the flight costs. This is where they part, and when.

Boston is the better pick in June to September; Mexico City in November to April; either in May and October.

Each cell is that destination's own verdict for the month — sweet spot, ok or avoid — with its typical daily high and its rainy days ("11d"). The pick goes to the better verdict; with the same verdict, to the higher score, unless the two are within a whisker of each other, when it is either. A month both would avoid is neither. A dot marks a busy month.

Between them

3,665 km as the crow flies, about 5h 23m in the air.

The flight time is estimated from the distance. A road, train or bus is named only where it was measured — flights from AeroDataBox, roads from OpenRouteService, timetables via Transitous — and none of it is a fare; the searches on each destination's page are where prices live.

Also compared

Every verdict here is the destination's own: ten years of climate readings, the public holidays that crowd it, and what the flight costs. The comparison is the difference between two pages, not a third opinion.
