About 11mm here and it could well stay below 15mm right up to the end of the month.
So this summer a strange pattern. A big NW/SE split in June with a soggy South and average or slightly dry North, and then the extreme opposite for 2 months in a row.
By end of August some places in the South may have had less than 20mm in two months, but the reason there's no drought is because of the deluge in early summer.
Similar state of affairs in France. Large areas South of Paris were having hundred year floods at the end of May, now those same areas are under drought restrictions and hitting the high 30s.
