Web alarm clock for 8:16 a.m.
You are waking up at 8:16 am, before you have started gathering your gloves, sack, and footwear to clear seaweed at low tide. This alarm gives you a clear cue to get out of bed and check the shoreline conditions without drifting back to sleep. With 9:00 am approaching, there is still room for a quick wash, some water, and a final look at the tide information before you head out.
Your seaweed clearing can start late if the alarm sound quietly goes to headphones left connected across the room. Before settling down, disconnect them or place them where the alert will be unmistakable, then keep the volume high enough to hear from bed. The alarm must remain active in an open browser on an awake phone; otherwise, your seaweed clearing may begin without its planned wake-up cue.
Once you are up, use the early start to protect a buffer before your next commitment later that day. Set out only the tools you expect to use, note when you need to leave the shore, and allow extra time to rinse sand and salt from your gear. That margin keeps the low-tide task from pressing into breakfast, travel, family plans, or work scheduled after 9:00 am.
