If it never snows where you are, then I can understand that you might find winter rather underwhelming. For me, the worst weather type is those nothing grey, dry, mild-ish drab days with nothing of interest happening. By contrast, a wet, breezy day like today is invigorating, especially if you dress appropriately (why do people go out in summer clothes and then moan that they're cold and wet?) and get out in it. That being said, lack of sun is a problem for many - my advice is to take vitamin D3 supplements (500-1000IU) and try to make the most of the cold, clear, sunny days. Consider, though, what it's liketo feel unwell every time the temperature goes over 30C and the relative humidity gets above 60%.
