Weather in Llangollen
Llangollen lies deep in the Dee valley, with the River Dee running through the town beneath Castell Dinas Brân. The steep valley sides shelter the town from strong winds but can hold low cloud and fog, and heavy rain upstream raises the Dee quickly, which matters for anyone on the river.
