Heat

I have been flying between Frankfurt and Stockholm at least 20 times in the last few years. Every time I noticed a considerable difference in the weather. I estimated the temperature to be in average about 5 degrees higher in Germany. This time, Sweden turned out to be warmer for the first time. And much warmer. I was able to take off two layers of clothes at ones. Nice. The north seems to give me a great welcome home.

By the way, I found a good slogan for the cheapest European airlines. Check it out:
Ryanair -- if it fits.
