Weekly note

Chamonix or Zermatt?

69 km apart, in France and Switzerland. 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.

Chamonix is the better pick in January, May and October to November; Zermatt in February and June to July; either in March to April, August to September and December.

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": days with at least 1 mm of rain, as a weather station counts them). 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

69 km as the crow flies, about 1h 00m in the air.

The flight time is estimated from the distance. A nonstop or a road is named only where a record has it — nonstop routes from Wikipedia's airport articles (CC BY-SA 4.0), roads from openrouteservice.org by HeiGIT — 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.
