Skylight: Weather & Radar

Skylight is a weather app for people who want to know how much to trust the forecast — not just what it says.

Every number tells you where it came from. Radar frames are labeled observed or forecast, never blurred together. Storm risk says it is reading forecast instability, not detected lightning. A trip three weeks out is answered by the climate record, and says so, instead of pretending to be a forecast. Where a provider has no data, Skylight shows you nothing rather than a confident zero.

On iPhone, iPad and Apple Watch. One purchase covers all three.

WHERE THE DATA COMES FROM
Forecasts come from Apple Weather, with Open-Meteo — drawing on the ECMWF, GFS and ICON models — as a fallback where Apple has no coverage. Air quality comes from the EPA's AirNow monitor network. Tides and hurricane tracking come from NOAA. Historical weather is reanalysis of the global climate record, which is a reconstruction rather than a reading taken in your garden, and Skylight says so where it matters.

Skylight Brief is composed from the forecast by rules, so the same conditions always produce the same words. Explain my forecast uses Apple Intelligence on your device — nothing is sent to a server, and it is held to the facts Skylight gives it.

No account. No ads. No tracking. Your location is used to fetch weather and is never stored or sold.
