Monthly temperature records by country
These records are based mainly on digitised data held by the Met Office. Last updated December 2011.
* Highest daily maximum and lowest daily minimum temperature records (including all records pre-1959) appear in Daily Temperature Extremes for Britain, J.D.C. Webb and G.T. Meaden, 2000. Weather 55, 298-315
Lowest daily maximum temperature records exclude stations above 500 m AMSL
When compiling these tables, an attempt has been made to verify all records by comparing values with neighbouring stations. A ^ symbol denotes some reservations about the record value quoted
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We do not quote highest/lowest maximum/minimum day-time and night-time records separately.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.
