Set the alarm clock for 3:15 am

Online alarm clock for 3:15 am

Hand over the Napier wharf tide-reading duty with a 3:15 am alarm set for the person taking your place. That gives them time to collect the notebook, check the measuring point and be ready well before 4:00 am, while you finish your part of the shift. Confirm who is responding before you step away, so the reading is not missed between two people.

For this tide check, the alarm needs permission to make a sound even if the phone is currently on silent. Set 3:15 am, choose an audible tone, raise the volume to a practical level and test it briefly before the handover. A browser alarm cannot protect the tide reading if its page is closed or the phone goes to sleep, so keep the page running and the phone awake until the alarm sounds. A separate device alarm is a sensible backup for the person taking over.

A night handover can carry sound through a quiet house, especially when someone leaves early for Napier’s waterfront. Ask the replacement to keep the phone close, use a moderate volume and move promptly when the 3:15 am alarm starts. Placing it on a folded cloth can reduce vibration through a bedside table while leaving the tone clear enough for its intended listener.
