Fire Watch : Fire & Smoke

New: the smoke countdown on your Lock Screen, Apple Watch and in StandBy. Plus burned land and air quality.

Fire Watch shows wildfires detected by NASA satellites across Europe and North America on a map, and simulates smoke plume movement from wind forecasts.

ONE SIMPLE QUESTION: IS THE SMOKE HEADING MY WAY? Tap any fire: Fire Watch simulates its plume hour by hour and tells you whether your location is in its path, and when the smoke could arrive. The simulation starts at the fire's first detection rather than the moment you tap it, so smoke already on its way is visible and the slider spans both past and forecast.

LIVE TRACKING When a plume concerns you, a countdown settles onto your Lock Screen with the expected smoke wave and the arrival marker. The scale adapts to the wait, from one to eight hours. Tracking also appears in the Dynamic Island, on Apple Watch with a dedicated layout, and full screen when iPhone rests on its charger in StandBy. For longer waits, a reminder warns you an hour ahead. Everything is computed on your device.

FRESH SATELLITE DATA • 4 satellite platforms (VIIRS Suomi-NPP, NOAA-20, NOAA-21 and MODIS Terra/Aqua), about 8 observations per day • Continuous age scale, from bright yellow to dark brown across seven days • Fire intensity in megawatts • Permanent heat sources recognized and set aside: industrial sites, gas flares, solar panel glint • The age of the most recent detection and the time of the last refresh are always visible

BURNED LAND • Areas mapped by Copernicus EFFIS across Europe • Official WFIGS perimeters in the US and CWFIS perimeters in Canada • An estimated footprint everywhere else, computed on device • Officially declared US incidents with name, size and containment

AIR QUALITY A colored veil marks areas where air quality is degrading, using the European index, with the value at your location.

A SERIOUS PLUME SIMULATION • Puff model: each puff is carried by the wind forecast at its own position and flight time, so the plume turns and bends as the weather evolves • Choice of wind model: automatic, AROME France high resolution, ECMWF or GFS • Hour-by-hour animation, adjustable parameters

BUILT FOR THE ESSENTIALS • No account, no sign-up, no ads • Your location never leaves your device • Data stays on screen even when a refresh fails • Automatic fire clustering by zoom level

IMPORTANT Fire Watch provides estimates computed from satellite data and weather forecasts. This information can be incomplete or delayed (1 to 3 h satellite latency) and never replaces alerts and instructions from local authorities. In an emergency, always follow official guidance.
