Tracking the rolling 12-month daily rainfall total allows a ‘real-time’ look whether an area is experiencing a drought or a deluge.

This week’s figure represents the 8th highest at this date since 1962. So not unusual. Until you look at the jump since last year. Some 303.6mm the past 12-months just pips the same period in 1976-77.

What is perhaps most noticeable is that this year follows last year’s negative fall which was the largest since 1961.

It’s one rainfall station BUT the results suggest a climate that is swinging more violently from one extreme to the other.
