Yes.. January, not so nice over here... Like a lot of places the weather has changed somewhat over the last decade or so..
When I was younger it was really cold from like October to February and would start to warm up a bit in about March... These days it stays fairly mild all the way up to December (no more white Christmas's for us).. The last few years its snowed in more like March/April time of year...
I don't know exactly why its happening but anyone who refuses to see the weather is changing globally are fooling themselves.
As for rain.. Well this is the U.K. . It does what it wants, no way to predict it at all, unless you are in Scotland where it just rains all the time 😄
