Bracketed values refer to departure from the relevant long-term climate average; note well that the month and year figures are adjusted for the current date, i.e. compared to the expected conditions for the month/year to-date, rather than the full period.
'Days of' require greater than 0.1 of the quantity (rain in mm or sun hrs).
Sunshine figures are not available for the current day so all periods are upto yesterday, rather than today as for the other variables.
