- When was the last white Christmas in Pant-y-Caws?
- The most recent modelled Christmas snow signal for Pant-y-Caws was 2009, in our 1991–2024 reconstruction. This covers falling snow on 24 or 25 December; it is not a verified observation of snowfall on Christmas Day.
- Was there snow on the ground near Pant-y-Caws on Christmas Day?
- Our Aberporth station archive, about 27 km away, contains no positive Christmas Day snow-depth observations among 10 recorded Christmases (1991–2000). Missing years are unknown, and the station does not represent every part of Pant-y-Caws.
- How many white Christmases has Pant-y-Caws had?
- Our reconstruction flags 3 of 34 Christmases in 1991–2024 for possible falling snow on 24 or 25 December. This modelled count is different from the calibrated long-range probability of 5%, and is not a tally of officially verified white Christmases.
- Why does the snow history end in 2024?
- That is the end of the currently processed HadUK-Grid model archive. Later years are not assumed snow-free. Nearby station observations have a separate coverage period and may extend further.
