When Is Winter 2024 Uk Time. On 27 october clocks will turn back by one hour, as we change from british summer time (bst) to greenwich mean time (gmt). Meteorological seasons consist of splitting.

So, astronomically, the winter season won’t start until then. The actual moment of the solstice in 2024 will occur at 9.21am gmt in the uk, but most people concentrate on the whole solstice day, which has been recognised by holidays and festivals in many cultures around the world.
