Maximum Central England Temperature, 2023

Month CET Anomaly notes
January 8.3 1.9 provisional to the 27th

  • Averages so far this year:-
    • Average CET to January: 8.32
    • Normal CET to January: 6.46
    • Anomaly to January: 1.86
    • Anomaly to January (year so far) *: 1.86

    * The anomaly for the year so far to January is calculated by taking an average
    of the monthly anomalies, weighted by the days in the month so far, over the total days in the year so far.
    This prevents the year so far anomaly value being skewed when calculated at the beginning of a month.

  • Comparison with Extreme Annual CETs:-

    The highest annual max CET ever recorded was 15.31, which is 2.22 higher than normal. To beat this record the
    anomaly must be higher than 2.25 for the remainder of this year

    The lowest annual max CET ever recorded was 10.54, which is -2.55 lower than normal. To beat this record the
    anomaly must be lower than -2.9 for the remainder of this year

  • This year's Daily Data to date

    Note that anomalies (and normals) quoted here are w.r.t. the period 1961-1990. This is a standard period
