Shown below are monthly weather summaries from the University of Reading (Berkshire, UK) climatological station. Observations are made each day at 0900 GMT.

Observations up to 0900 GMT on 26 May 2022 are included in the table.

If the date above does not match today's date, then there are still observations to be added to the database. This will apply particularly at weekends or when the University is closed.

Anomalies refer to the "month so far" for the current month, otherwise to whole-month averages - in all cases using data for the period 1991-2020.

Note that the mean temperature (and its anomaly) will, until the end of the month, refer to the average of the mean maximum and mean minimum temperatures applicable up to the day before that shown above - and therefore may not agree exactly with the mean maximum and mean minimum values shown in the table.
