Long winters are boring, long summers are boring, every season should last exactly for 3 months, with 1 week of gradual change inbetween. Monday and Friday, it should rain lightly, and Wednesday should be a fucking thunderstorm. Tuesday and Saturday should have no clouds at all, and Thursday and Sunday only lightly clouded. In Winter, the Thunderstorm should be on Friday instead of Wednesday, so that you have fresh snow on Saturday for skiing. Winds should vary every day, but in summer, they should be moderately strong on Saturday, so that you can go windsurfing.
