vis_km in WeatherAPI responses isn’t what most developers assume. Here’s what the field actually represents and how to avoid the common mistakes.
Fog detection via weather API is trickier than it looks. Here’s how to combine visibility, dew point spread, and condition codes reliably in your app.
WeatherAPI condition codes are not a direct METAR passthrough. Here’s what the mapping actually does, where it loses fidelity, and when raw data matters.
HRRR, NAM, and GFS aren’t interchangeable. Here’s how each model works, where each breaks down, and how to pick the right one for your app.
Wind shear data from weather APIs is often misread or ignored. Here’s what the numbers mean, why they matter, and how to actually use them in your app.
How to use WeatherAPI temperature, pressure, and humidity data to compute density altitude in real time — with code and the edge cases that bite pilots.
Learn how to programmatically detect IFR, MVFR, and VFR flight conditions from WeatherAPI data — with real thresholds, edge cases, and Python examples.
METAR strings are compact but full of edge cases. Here’s how to parse them correctly and fill the gaps with structured API data for aviation apps.
