Mean Central England Temperature, 2024

Note that the estimated mean value may not be equal to (max+min)/2 because there is always one more minimum
value than maximum. This discrepancy is exaggerated during the first part of the month and when the nights have
suddenly become significantly colder or warmer.  

• Averages so far this year:-
• Average CET to October: 11.75
• Normal CET to October: 10.27
• Anomaly to October: 1.49
• Anomaly to November (year so far) *: 1.46

* The anomaly for the year so far to November 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 mean CET ever recorded was 11.18, which is 1.71 higher than normal. To beat this record the
  anomaly must be higher than 4.22 for the remainder of this year

  The lowest annual mean CET ever recorded was 6.86, which is -2.6 lower than normal. To beat this record the
  anomaly must be lower than -42.22 for the remainder of this year
