Do you have the top driest years on record by any chance? Finding data is almost impossible unfortuantely for things like that and daily record highs/lows

1921 was the driest year, with 303.8mm recorded at Kew. Some parts of Kent recorded 270mm!
There were 102 days with trace precipitation. A normal year has 140-150 days with trace precip, and 109 days with >1mm. Maybe 60-70 days with >1mm if the ratio of rainfall to condensation was the same?
