Weekly note

Niseko or Seoul?

1,304 km apart, in Japan and South Korea. 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.

Niseko is the better pick in January to March, July and September; Seoul in April to June and October to November; either in August. December is best avoided at both.

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. Fares are the typical return from Bengaluru, in INR.

Between them

1,304 km as the crow flies, about 2h 30m in the air.Nonstop · 7 airlines. By road, 2,603 km and about 38h 47m.

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.

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.
