... I know I shouldn't get worked up about these things, but I'm getting rather tired of watching breathless weather presenters telling me that .... " June 2017 has been amongst the wettest on record ..." with no qualification at all in many cases.
However, a look at the Met Office's own map (below) shows that, as is often the case, the excess of PPN has been highly regionalised with Scotland, parts of the north of England, some extreme western areas of Wales having the 'wet', whilst large swathes of England & Wales (where an awful lot of people live) have had average, or below-average rainfall. It's sloppy presentation and diminishes the usefulness of such summaries. For the record, the provisional England & Wales PPN value means that I can find at least 35 Junes that were wetter than this one past, and down here, we've just about managed about 10% excess on 1981-2010 climatology. In SE Dorset, 90% of the rainfall for June came in just three 'rain-days' - with the majority of the month dry with lengthy periods of 'NIL' rainfall.
