No Snow In Assassins Creed III?

Perhaps you are in summer season you must few hours to get be in winter season

 

wha...? i'm sure if you play longer perhaps the snow will come

 

There's a pivot which allows you to change seasons, after you've finished the campaign and are on the epilogue (after credits) it should be one of the first pivots in Boston you find, I apologies if I named them wrong but yeh there is one to change the seasons to Summer - Winter

 

if you got to setting when you finish the game there is a setting on what weather you want
