How to use the online alarm clock
Break away from whatever has occupied you and get ready to begin your Coastguard watch. An alarm set for 2:31 am gives you a clear stopping point, while leaving 29 minutes before 3:00 am for putting things away, gathering your kit and switching your attention to the duty ahead.
Your Coastguard start depends on hearing the alert, so check the sound setting after choosing 2:31 am and setting the alarm. Silent mode can suppress the signal even when the volume was previously high; a quick test alert confirms what will actually be audible. Keep the browser running and the screen awake as well: otherwise the alarm may remain silent and your Coastguard duty could begin late.
Getting to a Coastguard station during the night may take less time on quiet roads, but closures, diversions and reduced overnight transport can make an apparently simple journey longer. Work backwards from the required arrival time, include the walk from parking or a stop, and leave a small margin rather than treating empty streets as a guaranteed shortcut. At 2:31 am, checking the route before setting off also avoids losing those remaining minutes to an unexpected turn.
Common questions
What happens if my laptop goes to sleep before 2:31 am?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
