Hi Barbarah
Don’t worry! The hedgehogs out early and those who choose not to hibernate are pretty much pioneers and still a minority. Most of the hedgehogs still hibernate and it is still early for them to be out.
The weather isn’t always an indicator of when and how long a hog will hibernate. Wild food availability can be just as important and some insects, etc. haven’t kept up with climate change and especially not with the occasional warmer than usual interlude. But even accessibility to food isn’t the whole picture either, with some males beginning to hibernate in September when there is still food around.
So you may need to wait a bit longer, but don’t give up. Historically some females have hibernated until April or later (having gone into hibernation later). Hedgehogs are notorious for keeping us all guessing, so hopefully you will eventually get some visiting again.
Good luck. Let us know when you get some hedgehog activity there.
