We often get asked this but are pleased to say that, no, they do not make a ticking noise. The Weather Clocks do, however, make a whirring or burbling sound for a second or two each time the weather forecast is updated. Most people like this as it means the changes get noticed as they happen (and children get very excited!) but would be why we don't recommend hanging a clock in a bedroom as they can change forecast any time of day or night!The Tide Clocks also 'burble' quickly every 30 minutes to update the tide scenery's height. This, again, can be not appropriate in a bedroom setting but absolutely fine in a living area.
