With 10% taken off NYC has 2,412 sun hours which is still above Calgary.

Plus the "claim" that it was sunny 3-4 days this week in London will not affect the 1981-2010 averages which you should know.
Why "claim"? Do you live here? No. If sun hours are repeatedly being underreported then it most certainly will affect the averages. Ask irlinit, who lives near me, and he will say the same thing.

Once again, an argument about London. Why are there no arguments about other cities?

It's not hard proof and if the sun hours are not being reported properly in your opinion maybe you can be the one who reports the sun for the met office as a job. Anyway back on topic. Cities with BWh climates can be humid which defeats the impression that every city with a BWh climate has dry air. Just look at the cities on Iran's southern coast.

Yeah, that's a rough estimate cut off. It's not really accurate to arbitrarily shave 10%. A 150 to 200 annual sunshine hours gap is reasonable between US and Canadian stations (or between Foster and CS devices). Even then that might only be fair to say in climates that see many days with intermittent clouds and sun. Places such as the desert southwest should not be nearly as effected by the difference in devices since the vast majority of days do not see much in the way of clouds.

Noaa gives New York 2535 sunhours in Central Park

Were the 2680 recorded at a different place?

I think Calgary and New York are about equal in sunshine.

Obviously London is a more pleasant climate than Calgary. One of the largest of images of British climate is that it's cloudy, the numbers agree with that. It's not a mistaken impression. But yea, at that latitude.

Because there are lots of British posters that mention London. And it gets more attention than equally gloomy cities such as Amsterdam since it's a large English-speaking city.

Maybe or maybe a different base period/POR

I found this 1931-1961 sunshine hours map for CONUS. 2600 hours basically runs through Chicago and NYC




and this map has a larger range but NYC and Chicago are within 2400-2800 shade

I think it would be close too. The Great Plains and Canadian Prairies get pretty good levels of sunshine

And one mistaken impression is that Salalah in Oman is extremely hot and dry in the summer when it is actually very cloudy and muggy in the summer.
What is a misunderstanding about the UK climate is the general belief UK dullness is entirely due to cold, rainy weather.

In fact, this is not the case. Compare sunshine totals for London with those for Sept ÃŽles in Québéc (blue), which gets about four metres of snow a year, and for Petropavlovsk-Kamchatsky in Russia (grey), which apparently gets over six metres of snow each winter, and you can see that there is actually more to the UK’s (genuine) dullness than mere abundant rainfall:

Month/London/Sept-ÃŽles/Petropavlovsk-Kamchatsky

January/61.5/104.0/105.4
February/77.9/134.4/115.8
March/114.6/150.8/176.7
April/168.7/170.1/192.0
May/198.5/223.4/192.2
June/204.3/221.2/192.0
July/212.0/240.9/170.5
August/204.7/220.4/176.7
September/149.3/154.0/177.0
October/116.5/131.2/158.1
November/72.6/93.5/123.0
December/52.0/93.7/93.0
Annual/1,632.6/1,937.6/1,872.4

Note how, despite being up to nine degrees cooler and twice and wet as London, Sept-ÃŽles still gets more sunshine in every month of the year, with the difference being greatest in the snowy winters. Patropavolvsk-Kamchatsky, with even snowier winters, gets the same sunshine – twice as much as relatively warm and dry London.

In fact, looking through UK climate data itself is enough to show the UK’s winter dullness is more than just getting a lot of rain. The famously snowy December 1886, with EWP of 145.2 millimetres and CET of 1.9˚C (no month so cold has been so wet) was by a large margin sunnier than any December since, with an estimated UK sunshine of 80 hours or almost twice the average. January 1959, another very snowy month, was clearly the sunniest January on record, and the cold, snowy November 1910, if not so exceptional, was about 25 percent sunnier than average.

The low UK sunshine is actually to a large extent due to “anticyclonic gloom” formed when the Azores High or a polar high extends into the UK, creating very dull, dry weather. December 1890 – the coldest December on record for the CET, but much less cold in Scotland and Ireland – is the most infamous case, but the relatively mild January 1996 and mild, dry February 1993 are just as extreme and more modern.
