Weather data comes from Open-Meteo, an open weather API that draws on national meteorological services. Search any location to see current conditions and the days ahead — temperature, wind, and the general outlook. Because World on Time is built around time zones, every forecast is shown in the location’s own local time, so “tomorrow afternoon” means their afternoon, not yours.
Checking the weather for somewhere you’re travelling to — or where a colleague or family member lives — is more useful when it lines up with their clock. Pair the forecast with the world clock or time zone converter to plan calls, trips, and outdoor events with both the time and the weather in view.
Conditions refresh regularly through the day, and forecasts extend several days out. Accuracy is highest in the near term and naturally softens further ahead.
Weather needs a live connection. If you’re offline, World on Time shows the last data it fetched — reconnect to refresh.
