So you would expect a build up!
Spring is a transitional month, building up to summer.
Not a sudden change to heat just because a mumsnet poster said it was summer on 21st June! Seriously!
you mentioned sudden change, not I.
And i didn't say it was summer on 21st, that's when the sun passes the equator and the northern hemisphere is facing the sun which gives us summer, its been that way for far longer than humans have been a thing, I haven't been back in time and had a word with big beard about it.
The entire UK is commenting on how cold it is yet of course someone has to go against the grain just because they want an argument!
Against the grain by mentioning a system that's eons old.. and i didn't start any argument, you branded my post "Nonsense", i was just responding.
Stick your heating on warm yourself up and have a think about it!
Very condescending and exclamation point heavy but, you'll be glad to know, I don't need my heating its lovely and mild here, and i have thought about it, I've considered the differences between the man made meteorological seasons and the astrological observed and measured seasons and i stand by the astrological and historical seasons and hope summer comes at the end of June and stays until Autumnal Equinox.
Have a great night. x
