Notes

This statement has been prepared based on information available at 10 am on Wednesday 1 November 2006. Basic checks have been made on the data, but it is possible that results will change as new information becomes available.

Normals are 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 for rainfall or 20 years of record for temperature, as they cannot then be calculated reliably.
