FGalah is right about one thing. Lots of CIDP's in Portmsouth. If you go on google streetview you see loads of them. London not so much at all. It will look very nice on that seafront in Portsmouth when all those palm trees are nice and tall. I think they should plant more palm trees all over the city. You'd never see that in these parts.
So 7 miles away and the sun hours increase by over 120 hours. How come everyone was saying that the difference between Detroit and Windsor couldn't be correct, yet the two airports are much further than 7 miles. Portmsouth must be some little isolated island of sunshine then compared to places surrounding it.
Yes. The figures are from Southsea, which is the southern part of Portsmouth & the weather station was right by the sea, even just 1 mile inland can make a big difference on the south coast, like I said it really is only the extreme coastal strip itself that sees more sunshine. Thorney Island is 8 miles from Southsea, Shanklin is only 11 miles from Southsea & Bognor is only 18 miles away (the 2 sunniest Met Office sites). So Bognor is only 10 miles away from Thorney island, but also receives much more sunshine. Portsmouth does indeed have its own little micro-climate, if you look on the regional maps you will see not only more sunshine is localised to Portsmouth, but also warmer temperatures (mean & in winter especially), less rainfall, little snowfall, few frosts etc...

Except there's a geographic reason for it: being adjacenet to the sea. Detroit and Windsor don't have one.
Well then maybe Boston does have a hundred or more hours than Blue Hill Obs given that Blue Hill is 12 miles inland from Boston.
You would expect some marine layer when the station is closer to the water. I don't know if it would amount to 100 hours a year in a span of 12 miles. Rockford which is 60 miles from Chicago. I don't have annual sunshine hours for Rockford, but I it is unlikely that it's that high. I could be wrong though.
Chicago is the least sunniest city in Illinois and the reason is that it's on the shores of Lake Michigan
Quote:
According to Dr. Jim Angel, Illinois State Climatologist, it isn’t Rockford. And that’s exactly what one would expect. Because the state of Illinois is long (from north to south), the city at the southern tip is the sunniest. Cities to the north are the cloudiest because of the persistent stormtrack, jetstream placement to the north. This makes Chicago the cloudiest city in Illinois (with additional clouds because of fog and a marine layer). -
Btw, I vote for London. Helsinki's winters are proper, but the rest of the year is too darn cold.

Yeah I was basically looking at the huge difference in spring and autumn which is why I gave London the nod. It looks as if I would enjoy winter there but not the rest of the year
Move away from the UHI in London, and the difference between the cities is minimal during the 5 warmest months. And Helsinki is sunnier.
Of course the shoulder seasons are much better in London.
Heathrow is not in the UHI (UHI doesn't affect daytime highs anyway).
Places such as Wisley and Haywards Heath are typical for rural locations in SE England, but they still comfortably beat Helsinki's temps in the warmest half of the year.
London for being warmer with more sunshine year round with still offering the possibility of snow a few times a winter. Helsinki is too gloomy in winter and it's latitude would mean depressingly low daylight hours.
