Explore recorded weather
Real airport weather reports collected by BadWx over time, covering the airports we currently monitor. Repeated reports are counted once per airport and observation time. Coverage has gaps: these are records within our archive, not all-time weather records or climate averages. Historical conditions are not live and are not loaded into MSFS.

A few things to know
What is BadWx?
A route finder for Microsoft Flight Simulator 2020 and 2024. It uses METAR observations and TAF forecasts to find fog, low cloud, storms and strong winds around your estimated arrival. Check the last-updated time and weather details before choosing a flight.
Does BadWx change my simulator weather?
No. Switch on live weather in your simulator. BadWx helps you choose a route; simulator conditions and your actual arrival may differ from the forecast.
How is arrival weather chosen?
BadWx checks the forecast around your estimated arrival. Open a route’s details to see the adverse weather window and raw METAR/TAF reports. Learn about arrival weather.
How do I create a flight plan?
Open a route in SimBrief with your airports and aircraft prefilled, then review and generate the plan in your SimBrief account. Read the SimBrief workflow.
