Online alarm clock for 2:01 am
Before handing the tide check to the next person, set the 2:01 am alarm so they know exactly when to take the reading at Napier’s wharf. Confirm which gauge to use and where the result should be recorded, rather than leaving those details for a tired handover. If they are staying through the next round hour, 3:00 am provides a clear point for checking that the observation has been logged.
Because the person taking over may put their phone aside while waiting, test the alarm sound and leave the volume high enough to hear nearby. Do not rely on this browser alarm as the only safeguard for the tide reading: if the browser is closed or the phone goes to sleep, no sound will play. A separate phone alarm or a reminder from someone on the same shift gives the wharf check a practical backup.
Working beside Napier’s waterfront at night can still feel warm indoors if the air conditioning has been running unevenly. Before the handover is complete, agree on a comfortable setting that will not mask the alarm with fan noise, and keep the phone away from the direct airflow. At 2:01 am, placing it on a firm surface near the log sheet makes the signal easier to notice without disturbing more of the building than necessary.
