Real-world weather for flight simulators
The whole world's weather.
Every 15 minutes.
FSGRW builds a global weather snapshot from live observations and model data: a full weather report for about 240,000 stations, from every airport to the open ocean. Your simulator flies through it.
Why FSGRW
Weather that comes from somewhere
Every value in a snapshot has a source. Observations come first; the model fills in only what nobody observed.
Observations first
A value is only calculated from model data when no usable observation provides it. A METAR's cloud base wins over the model's.
Combined value by value
Sources are combined for each value, not for each report. One report can take its cloud amount from a METAR and its winds aloft from the model.
No gaps
Stations cover land, coasts and the open ocean, about every 15 nm over land. Each has a complete report: surface, clouds, precipitation, winds aloft, turbulence and icing.
Products
One weather source, one product per simulator
The snapshot doesn't depend on any one simulator. Each product turns it into its simulator's own weather model: X-Plane 11, X-Plane 12, MSFS 2024, FSX and Prepar3D 6 so far. Every product can also fly the weather of a past date and time, up to 30 days back.
FSGRW for X-Plane 12
Weather that varies across the map, the way it does outside. Distant storms are visible as storms, and the weather at the airport matches its ATIS.

FSGRW for MSFS 2024
The same global weather for Microsoft Flight Simulator 2024. The weather where you fly, from the ground to the flight levels, updated while you fly.

FSGRW for Prepar3D 6
The same global weather for Prepar3D v6. Every station around your aircraft gets its current weather, from the ground to the flight levels, with Prepar3D's volumetric clouds.

FSGRW for FSX
The same global weather for Microsoft Flight Simulator X. Every station around your aircraft gets its current weather, from the ground to the flight levels.

FSGRW for X-Plane 11
The same global weather for X-Plane 11. The airports around you get their current reports, and the winds aloft come from the FSGRW snapshot.

FSGRW for FS2004
The same global weather for FS2004. Weather stations all around your aircraft get their current weather, from the ground to the flight levels.
