Longest dry spell (days under 1 mm of rain), within one year

Consecutive days with less than 1 mm (0.04 in) of rain, the longest run within a year. The dates are not kept, so the list gives the year (within the year).

Longest wet spell (days with 1 mm or more of rain), within one year

Consecutive days with 1 mm (0.04 in) or more of rain, the longest run within a year. The dates are not kept, so the list gives the year (within the year).

A run belongs to the year it started in, even when it ran on into the next year. A station appears once per list, with its longest run in a complete year. Dry and wet spells are the longest run within a year. Lists use complete years only, so a long run in a year with gaps in the record is not counted.
