Tripping when it's snowing is magic. The snowflakes are hypnotic and feel "kind" when they touch you. Since up here in the North the variation between summer and winter is so huge, it obviously affects tripping.
Summers, when it's light 24/7 (the sun does set for a few hours here but it's still not dark), and winters, when there's light only for a few hours. So tripping in the summer is tripping in constant light, while tripping during winter is tripping in darkness basically from the beginning to the end. If you're outside, obviously

The last couple of winters have been so snowy and cold I wouldn't have wanted to trip outside though. Sensations get a bit twisted and you don't always recognize the pain of coldness in your hands or feet. Or then you feel cold somewhere, but can't always localize the place (e.g. fingers). So I prefer the summer and the light, the mystic in light nights (I don't live as far up north as to witness the midnight sun though) is amazing.
What I would want to experience though is to travel further up north and witness Aurora Borealis in winter and the midnight sun in summer while tripping. They're both spectacular even on their own.
