San Francisco or Seattle?

1,093 km apart, both in United States. 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.

Month by month

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.

Before you go

Both are in United States, so the currency, the plugs and the travel advice are the same: type A and B plugs, driving on the right, paying in the United states dollar. Everything for United States.

Between them

1,093 km as the crow flies, about 2h 15m in the air.Nonstop, about 23 a day · 4 airlines. By train, about 23h 11m · 11 · 527. By bus, about 22h 04m · Greyhound US0500 · Greyhound US0870.

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.
