The data above are for the month of May 2023 ending at 06GMT on day 01.

Averages refer to the period 1991-2020 in all cases.

09GMT MSL Pressure (mb) : mean, highest and lowest MSL pressure at 0900GMT
Rainfall (mm) : total starting 0600GMT/1st, and greatest 12-hour fall ending 06GMT or 18GMT
Maximum Temperature (degC) : for the period 06-18GMT, mean, highest and lowest
Minimum Temperature (degC) : for the period 18-06GMT, mean, highest and lowest
Sunshine (h) : total and highest daily value
Mean Temperature (degC) : the average of the mean maximum and mean minimum
Temperature anomaly (degC) : the departure from the climatological average
Rainfall percentage (%) : the monthly total as a percentage of the climatological average
Sunshine percentage (%) : the monthly total as a percentage of the climatological average (an asterisk denotes site now uses a Kipp-Zonen instrument). This change was made to the tables on 27.08.2008. Climatological averages are for 30-years of pseudo-KZ observations in this case)
Pressure anomaly (mb) : the departure from the climatological average
