How come British meteorologists announce "the end of summer"?

Question

...Twenty days early? Officially, northern hemisphere summers end September 20?

Answer 1

Well they might as well be in Ireland too, we had our 1 day of summer for this year and it was this Saturday just gone, I took a photograph of 2 peacock butterflies on the buddlia as proof for the disbelievers out there.

Funnily enough the frost came a month early last year, usually 20 October thereabouts we can expect the first ground frost but last year it was 25 September.  

I blame our American friends for everything.  

Answer 2

There is a definition called meteorological seasons, not just in Britain. When it started and who started it I don't know. I only heard it last year for the first time.

Answer 3

I remember some years ago, there was a program on T.V called "Tomorrows world" in one episode they said they would soon be able to change the weather to suit. I often wonder if the weather we are now getting, is a consequence of their scientific meddling.

Answer 4

I hadn't actually noticed that the summer had even started this year!

Answer 5

For meteorological purposes summer is june, july and august. Autumn is september, october and november.

Answer 6

Ah, that is coz summer is wet and mild whilst winter is wet and cold. Warm and dry is as rare as snow on Christmas day.

Answer 7

Summer = rain, rain, rain, rain and more rain for Britain.  

Answer 8

apparently, meteorologically speaking autumn started today, don't know why. maybe they just go by each season being 3 full calendar months.

Answer 9

Because we only get one day of summer, and that was Saturday!
