This map shows the number of consecutive "sunwave days" from official sites up to the selected date, combining data from non-QC'd SYNOPs and the Met Office's QC'd MIDAS database. A "sunwave day" is arbitrarily defined as any single day where either the daily sunshine total exceeds 12 hours, or 90% of the theoretical maximum for that day (you can choose which measure to use). A "sunwave" could be plausibly said to have occurred when 3 or more consecutive "sunwave days" occur.

Data is available from 1887, to the present day. All times quoted are GMT.
