This unweighted mean of monthly means describes an aggregate across months, not a day-weighted annual average or a monthly rainfall total.

This is an unweighted average of monthly means rather than a day-weighted annual figure. September had the largest monthly decrease in mean daily sunshine, with a difference of -0.46 hours/day.
