With September 2023 breaking global records, where does the UK sit? Author: Press Office 5 October 2023 September 2023 was the world’s warmest September on record for global average temperature according to the Copernicus Climate Change Service. The September average temperature was 16.38°C which is 0.93°C

.  Monitoring global mean surface temperature is useful because it is linked to many important climate impacts and it has a long and reliable historical record.  However, Earth’s surface temperature, even its global average, is strongly affected by internal climate variability, and is not necessarily

This April, the UK experienced a range of weather conditions and while no new records were set, we take a look at how this April compares to years gone by

As we head towards the end of the month, we can use Met Office data to compare how the weather experienced in April 2025 so far compares to years gone by, and which years hold the records for certain extremes. Temperature Extremes In April 2025 so far, the highest daily maximum temperature
