Spring versus Fall

The sun has been out quite a bit over the last month or so in southern Finland. Apparently, unlike much of the US, spring is the dry season in Finland and skies are mostly clear a lot of the time. For example, in Helsinki, May is the driest month with 10 days with more than 0.1 mm of precipitation. In contrast, Albany and Oklahoma City have maxima in the number of precipitation days per month in May, with a less pronounced annual cycle.
