What are the driest parts of the british isles?

The driest parts of the British Isles are primarily found in the southeast of England, particularly in areas such as East Anglia and the Thames Valley. The region experiences lower annual rainfall compared to other areas, with some locations receiving less than 600 mm (about 24 inches) of rain per year. Additionally, the rain shadow effect created by the surrounding hills and mountains contributes to the dryness in these regions.
