Does Summer in England start at an earlier date than the rest of the Northern Hemisphere?
True astronomic summer starts in just a few more days, but it already feels like deep summer in the UK, as the weather has been exceptionally warm (hot by their standards).
The (almost) northermost town inside the US, Ft. Kent is at 49’25 North. The southern most in England is Lizard Point, Cornwall, at 49’ 57.
So, that’s why England gets a late start. It’s all above Maine.
