Where Ascot’s numbers come from

Averages over 30 years, not a forecast.

  • Mean temperature, rain and day counts: HadUK-Grid 1991–2020 averages for the 1 Met Office 2 km grid square whose centre lies inside Ascot’s built-up area.
  • Highs and lows: the Met Office publishes average daily maxima and minima on its 12 km grid; each is moved by the difference between the town’s 2 km mean temperature and the 12 km square’s, which carries the town’s own height and setting over.
  • Weather station and sunshine: Met Office historic station data for Heathrow (London Airport), 11 miles away, months of 1991–2020 averaged.
  • Comparisons: every town and city of 2,500 or more across the UK, all four nations, read the same way.
