US Weather Wake Up (Java Version) allows you to set an alarm clock to wake-up you up earlier or later depending on actual weather conditions at the time of the alarm.

You specify the weather criteria and the (US) location of the weather conditions you want the alarm to monitor for deciding between an early or later wake-up.

E.g. a weekend sailor might set his or her Sunday morning alarm to 6am provided the weather conditions in his or her location at 6am show sufficient wind and no gales or thunderstorms, but delay the alarm until, say, 7:30am if the weather is not favourable for sailing.

Or, a weekday commuter might specify an alarm half an hour earlier than usual if snow is falling and slowing the roads, or half an hour later if there is no snow.

Whether you're a golfer, sailor, hiker, biker, photographer, or any kind of outdoor hobbyist, sportsman or sportswoman, this alarm is for you.
