Does Radlett get more rain than nearby London?

Is there a weather warning system for Radlett?

How does the weather affect school holidays in Radlett?
Hertfordshire school holidays follow standard UK dates. The live forecast above helps plan half-term breaks, but spring and autumn are generally mild, so outdoor plans are usually fine with a light jacket.
