Notes

  • Temperature records began on 1st Jan 2009
  • Figures in brackets refer to departure from average conditions
  • An air frost requires the overnight (21-09) temperature to fall below freezing
  • All figures, unless specified, relate to the period midnight-midnight, this being when daily extremes are reset.
Definition of 'Feels-like' temperature: This displays either the Wind Chill index or the 'Humidex', depending on the temperature and humidity. These indices are attempts to depict what the air actually feels like on a human's skin - either from the warming effect of high humidity, or the cooling effect of the wind. However, they have little physical meaning and their valid use is debatable, so are provided for interest only.
