Ours are always a week later than my parents' ones, even though they live only 10 miles south of us. They are however lower and nearer the sea.
As a comparison, our daffs are only just poking their leaves above soil level now. My parents' ones are about 6" tall, but have no flower buds yet.
We are all obviously quite a bit behind ........
