Snow in Caernarfon: what to expect
Caernarfon is in Gwynedd, in the Met Office’s Wales warning region. At around 12 m above sea level, Caernarfon is low-lying, so snow here often turns to sleet or melts unless the cold air is well established. Of the last 5 winters, the snowiest here was 2024/25.
The answer above is worked out for Caernarfon’s own position. YES means snow is falling now, SOON means it is forecast in the next 24 hours and NO means neither, with a note if ice, freezing rain or lying snow could still cause trouble.
Will it settle?
Snow only settles when the surface it lands on is cold enough. The air can be below freezing while the ground is still holding heat from a mild week, so the first flakes melt as they land. We look at the forecast ground temperature as well as the air: at 0°C or below, snow settles almost everywhere; between about 1°C and 2°C it collects on grass, car roofs and garden furniture first while roads and pavements stay wet; above that, most of it melts. Heavy snow can beat a warm ground by cooling it, which is why a short burst often settles when a long, light fall does not.
