London or Paris?

344 km apart, in United Kingdom and France. 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.
