Online alarm clock for 4:47 pm
You’re wrapping up an evening surf as the wind drops, and 4:47 pm is the moment to catch the last wave, paddle in and start heading off. Setting the alarm now gives you a clear finish point without repeatedly checking the time from the water. By 5:00 pm, you can be rinsing the salt from your gear and making your way out of the beach car park.
With wet hands and your attention on the swell, the alarm sound needs to reach the right place. Check whether your phone has quietly routed audio to headphones tucked inside a bag or left in the car, then set a volume you can hear near your towel. A browser alarm depends on the page remaining open and the phone staying awake; otherwise your surf pack-up may pass without any sound. A quick audio check before paddling out helps confirm where the alert will play.
Leaving the water at 4:47 pm can protect the sleep you want later, especially when an afternoon session could otherwise stretch into dusk. Allow enough time to dry off, secure the board and have a calm trip home rather than turning the final minutes into a rush. Keeping the finish near 5:00 pm also leaves space for dinner, a shower and an easier wind-down before bed.
Common questions
Will the alarm still ring if I close the browser tab?
No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.
Does the alarm work if my laptop goes to sleep?
Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.
Do I need to create an account or download anything?
No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
Can I change the alarm sound?
Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.
