Notes
This statement has been prepared based on information available at 12 pm on Friday 1 June 2007. Some checks have been made on the data, but it is possible that results will change as new information becomes available.
Normals are long-term
means based on observations from all available years of record, which vary widely
from site to site. They are not shown for sites with less than 30 years of record(except
maximum temperature with 10 years record), as they cannot then be calculated reliably.
The median is sometimes
more representative than the mean
of "normal" rain.
