I've looked up the sunshine hours for some North American cities and when i came across New York which apparently has over 2600 hours of sunshine i was quite shocked. A city that certainly isn't known for being very sunny is up there with some of the sunniest parts of Spain, Italy, Australia, France, New Zealand etc. Surely this can't be right. Boston also has similar sunshine hours to the likes of Sydney??? I'm not sure if this has already been discussed but i just wanted to know how accurate these numbers are?
US uses a foster to record sunshine which overstates sunshine compared to other worldwide locations. You're right, no way NYC is as sunny as some northern med places

Do you know where i could get the accurate numbers?
From what I heard, the US system "adds" 150-200 hours. If you subtract that number, NYC and Chicago would have around 2350 sunshine hrs and Los Angeles would be at 2900 or 3000 hrs.

Do you know if the same goes for Canada? Most of the Toronto area has 2100-2200 according to wikipedia, and I always thought of it as "unfair" that Boston and Milwuakee both get like 2500 when they're all kinda similar climate wise

Reason for the "difference" is US sunshine hours are inflated by about 150 to 200 hours,
Canada stats are not.
Toronto annual sunshine hours if calculated using US recorder would be about 2400 hours
US annual sunshine hours are inflated ....not Canada.
I believe Canada used CS (Campbell Stokes) Sunshine recorders, same as in the U.K.
I say "used" ....I don't think Environment Canada bothers to record sunshine hours anymore,
same with NOAA in the States.

So the UK also has inflated sunshine values? Their sunshine values must be really sun****e...
