Weather and Moods

WEATHER, CLIMATE AND MOODS

I am surprised at how locations and weather can change a mood. The photo is the view I can see whenever I want. But this week I am in England, where the weather is grey and damp, chilly and not very nice. My happy and relaxed mood is steadily getting more unhappy and tense, and I am so looking forward to returning to where I feel comfortable.
I have a friend who was born and raised in a warm sunny climate, but loves being in England and winter is her favourite season. This is something I can't understand.
Is this SAD or is everyone affected by weather and climate in one way or another?
