Well, late summer or early fall would be convenient for Sunhee since she's been "recently" changing things up.  That would mean she gets to be redoing her life a little just as the stuff hits anyway.  On the other hand, it might still be so warm that it would look odd for anyone who looks much over 30 to be wandering around some parts of the city with long coats (such as those that might better conceal large weapons), etc.<br/><br/>If it gets more into fall, a little chilly and more frequent patter or drizzle...<br/><br/>Winter is dark enough that a powerful vampire (yes, sliding across the different series) hardly needs more than 4-6 hours in the coffin.  Some days, less.  Snow becomes completely possible, though not common.  Some people who can afford it, depart the area for places with more natural light.  Some days a touch of drizzle, some days the rain just will not end.<br/><br/>Spring has some awesome blossoms in places, otherwise tries to make up its mind between fall and winter.  (There must be more, but I'm mostly thinking of light, temperatures, and rainfall right now.)<br/><br/>Then there is summer proper (all two-three months of it) that is just gorgeous most years: drier, occasional rain with rainbows, nice warm or hot temperature range, you can actually<em>see</em>the mountains all around more often...  And young things like Sunhee would be on vacation, working part-time, or (in her case) picking up something new as soon as possible.<br/>
