Why have we done this?

National weather records are shown in the tables below. Last updated December 2011.

These weather records are only given for stations with standard instruments and exposure, to ensure consistency. Although there are a few instances where records have been broken by non-standard stations, these are not accepted as official records for this reason.

More information about daily temperature records.

All daily maximum and minimum temperature records quoted below are based on the period 0900–0900 GMT

Automatic weather stations also report day-time 0900–2100 GMT and night-time 2100–0900 GMT maximum and minimum temperatures.

Day-time and night-time values should not be compared directly against daily records, particularly for highest daily minimum and lowest daily maximum. In some unusual weather situations the day-time minimum may be lower than the night-time minimum. Alternatively, the night-time maximum may be higher than the day-time maximum. In either situation this makes a comparison with the daily records invalid.

We do not quote highest/lowest maximum/minimum day-time and night-time records separately. The main reason is that manual climate stations only report daily 0900–0900 GMT maximum and minimum temperatures. These manual stations form a significant proportion of the overall station network, particularly further in the past. Therefore the compilation of day-time and night-time temperature records would be based on an incomplete station network.
