Very low dewpoint recorded around 14:00 UTC on 5/4/21:

-12C with corresponding air temp of 6.1C giving a humidity of 26%

Conditions were bright sunshine, exceptional visibility with 8kt NW wind.

It followed after a rapid drop after 13:00  from  -7C so a rapid influx of very dry air had occured. It remained below -10C for a further hour before slowly rising during the later afternoon and evening.

This was my lowest recorded dewpoint since 24-25 Dec 2010 when -14.9C was recorded. For comparison, the lowest during the cold spell of late Feb/early Mar 2018 was -10.4C on 28 Feb.
