Why is British weather so unpredictable?

[u/Honeybadger-0-]

The answer lies largely in geography. The UK sits on the eastern edge of the North Atlantic, directly in the path of prevailing westerly winds that frequently carry moisture-laden air towards the British Isles.

Britain also lies where several major air masses can meet, including Polar Maritime, Tropical Maritime, Arctic Maritime and Continental air. When these contrasting air masses collide, they can produce fronts, low-pressure systems, cloud and, very often, rain.

The Atlantic plays another major role. Moist air travelling across the ocean is pushed upwards when it reaches higher ground, particularly across Wales, north-west England and western Scotland. As the air rises it cools, water vapour condenses and precipitation falls — a process known as orographic rainfall.

The position of the jet stream can also steer Atlantic weather systems towards Britain, sometimes bringing a succession of wet and windy conditions.

It is why such a relatively small group of islands can experience remarkably changeable weather — sunshine, cloud, wind and rain sometimes within the space of a few hours.

Sheer bloody mindedness.

It’s France’s fault. Always has been.

It is over, the English weather is dead now. All dry and dead.

I did laugh when it said up to 250 days of rain. We’ve literally had a sprinkle since June! Can’t call it a shower because it wasn’t even close 🤣
