The wettest areas of the UK are in the north of the west of the country, particularly where there is high ground.
The prevailing warm moist westerly winds mean that the west of the UK is more likely to receive rainfall from Atlantic weather systems. These weather systems usually move from west to east across the UK and as they do so the amount of rainfall they deposit reduces. This is because the mountains in the north and west of the UK cause lots of the rainfall to fall in those locations as the clouds are too ‘heavy’ to move over the higher ground.
The table below shows the average annual rainfall for the top ten wettest places in the UK.
