How this is worked out
Every figure is a decade of weather-station observations blended into one typical year, read at midday local solar time, in ten-day sections. A season is quoted for the country only where at least 60% of the 5 cities counted agree it is Good. Being outside is the Easy outdoors rating, Sun is Sunbathing and Walking is Active outdoors, each out of 100: Good from 55. It is what a time of year is usually like, not a forecast.
