Office 10-day trend: A tale of two halves for September Author: Press Office 25 September 2025 September has been a month of contrasts across the UK, with the weather delivering a tale of two halves. The start of the month was unsettled, bringing plenty of wet weather and changeable conditions. However

to the west creates an environment that is frequently cool, dull and wet. However, the Pennines can cause the cloud to break up downwind, meaning warmer days but cooler nights. If low winter temperatures coincide with high winter precipitation, heavy winter snowfall may occur across Kirklees. Snowfall

experiences more cloudy, wet and windy weather than regions further east. Some upland areas experience harsh weather whilst coastal and lower lying areas enjoy more favourable conditions. Winter mean daily minimum temperatures vary from 0°C in high parts of north and mid-Wales to 3 or 4°C around the coast

decades. • Over land the projected general trends of climate changes in the 21 st century are similar to UKCP09, with a move towards warmer, wetter winters and hotter, drier summers. However, natural variations mean that some cold winters, some dry winters, some cool summers and some wet summers

of a particular place is often described in seasonal periods (e.g. summer/ winter or rainy/ dry season) over the cycle of the year.   The climate can also naturally vary between different years due to the process of Earth system cycles, especially those associated with large circulations of the oceans

of carbon dioxide from the atmosphere. This occurs because La Niña cools the ocean temperature and modifies tropical weather patterns, making many land regions wetter and allowing plants to grow better and absorb more CO2.  2016 saw a record rise due to a near-record El Niño event in addition to high

Observations from 1981-2010 show a moderate increasing trend in temperature compared to other regions of the world, but as the region has a narrow climatic

The strongest winds were around Irish Sea coasts, particularly west Wales, with gusts of 60 to 70 Kt or higher in exposed coastal locations.
