Monthly number of rain days in the UK 2015-2024

There were nearly 13 raindays in the United Kingdom in July 2024. A rainday is when one millimeter or more of rain occurs in a day. The highest number of raindays was recorded in December 2015, at 22.2 

Fourth quarter the wettest

The wettest periods of the year tend to be the start and the end. In 2023, the fourth quarter was the wettest, with an average of 419 mm of rainfall. October and December of that year recorded the highest levels of monthly rainfall at 177 and 189 mm, respectively.

Regional weather

Due to the United Kingdom’s geographical location and landscape, weather conditions can vary greatly. Scotland is on average the wettest country. The majority of rainfall is concentrated in the Scottish Highlands, as precipitation often occurs in mountainous regions. As rainfall comes in from the Atlantic, it is the northern and western parts of the UK that are most susceptible to precipitation. This explains why England is the driest of all the regions, as rain deposits reduce as they move east.
