I suppose we can end all the nonsense about a sunny winter day in New York or Philadelphia or Richmond, VA feeling as warm as a winter day in London then, if there's no difference in sun strength? Or is sun angle only allowed to be mentioned when London loses out as a result, but not when it's in favour?
Of course there is a difference. Richmond is at 37N, that's a 14 degree difference from London, and you notice the difference during the shoulder seasons. But arguing about two high latitude places is a completely different story. You will notice absolutely nothing in June between London and Uppsala.
So there's no difference in sun strength between London and the Med? London is mid-latitude, not high-latitude anyway (Uppsala is just about mid-latitude as well).
So the 8 degrees of latitude between London and Uppsala has no difference in sun strength, yet the 8 degrees of latitude from London to the Med coast has a difference? What rubbish.

You feel the difference much more though, so I can see where he's coming from. The sun isn't really that strong here in summer, and tbh, I couldn't tell that much of a difference even at 68N. The sun is beginning to feel strong in the med though, it's much more noticeable don't you think?

HESUS!
Your original statement was that London feels a lot hotter in summer due to the higher sun angle. I said no, as the sun is at it's zenith for merely less than an hour a day, and humans aren't sensitive enough to notice a difference between a 45 degree sun or 50 degree sun. By both locations being on a high latitude, the sun moves in arch, and the difference in solar altitude is minnow.
Meanwhile, for example on 1 March you can notice a difference in sun strength, and the closer you move to the equator the easier it is to notice.
The sun angle on 1 July at 10 in the morning is 43 degrees in Uppsala. In Miami it's 44 degrees. Do you notice a difference: no. Do you notice a difference during solar noon: yes.

I certainly feel a difference in solar irradiance between Chicago (annually 3.72, peaking at 6.1 in June) and Miami (annually 5.26 peaking at 6.6 in May) depending on the season, but it would be less during the summer.
Can't find Upssala's solar irradiance, but Oslo's (same latitude and nearby) is 2.27 annually and peaking at 4.84 in June. London's is 2.61 annually and peaks in July at 4.61. Looks pretty similar to me. http://www.leidi.ee/wb/media/INSOLAT...EVELS%20EU.pdf

Which was in response to Rams_Lord saying that the summers were basically the same, even though London is noticeably warmer in every month, with stronger sun as well.
I recall many people saying that Seattle (which has pretty much the same summer temps as London) and Paris (which is to London, as London is to Uppsala), were much warmer and had noticeably stronger sun than here, even though they are 2 degrees further south.

I was talking temperature wise, comparing sun strength between these two cities would be rather silly both don't even have strong sun to begin with...
Uppsala gets around 2 more hours of sun than London daily in July, also.
