I take issue with you there Graham.
You
say "normal" is 111.3mm. That might be the average, or the mean, or the
median. I would have thought that your figure to date of 76.3mm is well
within the "normal" range.
There is no such thing as "normal" temperature, rainfall, sun or what have you. Average, median, etc. yes.
