Scotland is famous for its weather probably all over the world. I don't think there are many places which can boast about worse weather conditions than here.
So what is the weather like here? In short, it depends. Unlike in much of mainland Europe, you don't really see clear distinctions between different seasons when it comes to atmospheric conditions. It's true that the skies are (almost) never clear in winter as opposed to summer when it can be sunny sometimes even for several consecutive days, but temperatures rarely rise or drop significantly. If you don't like heat, you'll most probably find the Scottish summer pleasant but if you, like me, love the sun, go further south, preferably until you reach the Mediterranean.
Because summers are so short and almost negligible in comparison to the rest of the year, and winters are not true winters like I used to know them, I like to say that there are only two seasons here - light and dark. I think naming them like this is more appropriate.
It was the longest day of the year just a few days ago and, although the sun was below the horizon, it didn't get dark until after midnight, and only then it wasn't long (about three hours) before it got light again. Combine this with temperatures in the 20s and you're in for a lovely experience.
Wintertime, I'm afraid, is quite a different story. Long dark hours and almost constant rain and wind can really make you depressed.
The weather here is also very changeable. Some say that there can sometimes be all four seasons in one day. I personally wouldn't go as far as that but it is true that after a warm and cloudless morning, the sky can become completely clouded and temperatures can plummet rapidly only to go back to how they were just a few hours earlier.
