Factors Influencing September's Weather

Several factors contribute to the UK's varied and often unpredictable September weather:

The Gulf Stream: This warm ocean current moderates temperatures, especially in the southern and western regions, leading to milder conditions than other areas at similar latitudes.
Atlantic Depressions: Low-pressure systems originating in the Atlantic Ocean bring frequent rainfall and changeable weather to the UK, particularly in the west and north.
Jet Stream: The position of the jet stream influences the weather patterns, directing Atlantic storms towards the UK or pushing them further north.
Altitude: Higher elevations, like the Scottish Highlands or the Welsh mountains, tend to be significantly cooler and wetter than lower-lying areas.
