I spent three weeks in the British Isles during the month of January back in the 70’s once, and I was amazed at how warm it could get from time to time. In fact, I remember being so impressed at how green Ireland was at that time of the year and was told, “That’s because of the Gulf stream.”
They were referring to the Gulf Stream from the Gulf of Mexico, believe it or not. Apparently, it can have a big effect in that neck of the woods at that time of the year.
I remember that the entire time I was in Scotland, I NEVER saw the sun. Not once. On a side note, I’m a pretty well-traveled man, and I have never been ANYWHERE where the people were as warm and kind as they are in Scotland.
Finally, in England, it was rainy and damp the entire time I was there. That, I think, is typical for that time of the year. I might also suggest that you Google “Weather By Month In England (or Scotland)” and read what they have to say about average temps and rainfall amounts.
Then, of course, that WAS in the 70’s when I was there. There was that Global Cooling thing going on back then, if I recall.
