GNUtrino is bag on. The village used to be recorded as Gherinstone, Garsington, or Gersington. It’s a mix of Old Norse and Old English, meaning something like “the town with the grassy ings” (an “ing” is a dialect term for a meadow near a river).
Aye, well for July what seems to have happened is that wave after wave of low pressure systems have been dropping lower across the Atlantic, crashing into Britain, and pushing high pressure systems further south into southern Europe, where they’ve been experiencing record-breaking high temperatures.
Well the UK has been getting increasingly warmer in the last few years, which has often been accompanied by extended periods of dry weather. The Lake District in Cumbria typically receives most of the rainfall that comes across the Atlantic to these isles, but we’ve had a lot of summers recently where it didn’t rain for months. This July, by contrast, has been very wet and cool.
