...for the same reason that determines the price of a house...location! The British Isles sit smack on the boundary of three weather zones - The Mediterranean, Continental and Maritime zones - which means we can get loads of different types of weather depending on the wind direction. The predominant weather is maritime - a prevailing wet westerly wind coming off the Atlantic.
As for Summer weather, that depends on the Jet Stream, a high-speed high-altitude current of air that runs west to east over the top of us. It is along the track of the Jet Stream that depressions (wet-weather systems) run. In Summer, the Jet Stream can often shift direction and head North-East rather than due East. In this case, the depressions all miss us and pass by to the north. All too often, it just keeps right on going over the top of us! If it's in a fickle mood, it will waggle a bit, so we get a mixed Summer. So, if you believe in the power of collective will, let's all push the Jet Stream north with our intention and get a well-deserved blistering-hot Summer!
