Scientific Explanation: Why is September Weather in London like this?

The shift in London's weather in September is a consequence of several meteorological factors. The most significant is the change in the position of the sun. As autumn approaches, the sun's path across the sky shifts southward, resulting in shorter days and less direct sunlight. This reduction in solar radiation leads to a decrease in average temperatures.

Furthermore, the jet stream, a high-altitude wind current, becomes more erratic in September. This increased variability leads to the passage of more weather systems across the British Isles, resulting in increased rainfall and greater temperature fluctuations. These weather systems often originate from the Atlantic Ocean, bringing with them moisture and cooler air masses. The combination of shorter days, decreased solar radiation, and more active weather systems contributes to the characteristic weather pattern experienced in London during September.
