You have seen the relative average summer sunshine figures for Glasgow / Prestwick versus Tromso in the North or Norway?
Glasgow & Prestwick [April, May, June, July, August, September]
134.5 180.1 158.9 154.3 146.8 114.9
Tromso [Same Months]
160 218 221 205 167 92
Seems a bit more realistic to me to call northern Norway a Sun Destination than Prestwick...............
Prestwick was never called a sun destination though:P Nor should it ever be called one. You may get away will calling south east UK a sun destination, but that's it, but even there you will face a little trouble:P.
