WeatherAPI condition codes are numeric — but mapping them to user-facing text in multiple locales breaks in subtle ways. Here’s how to build around it.
SWE is missing from most weather API responses. Here’s why, and how to estimate it from totalsnow_cm, temp, and humidity fields you already have.
Visibility fields in weather APIs behave differently after dark. Here’s why vis_km breaks down at night and how to build fog detection that accounts for it.
feelslike_c can mislead at high elevation. Here’s why wind chill and heat index break down above ~2000m, and how to flag it in your app.
WeatherAPI returns precip_mm of 0.0 even during light rain. Here’s why trace thresholds exist, what they mean for your logic, and how to handle it correctly.
Weather alert deduplication isn’t just checking IDs. Here’s why alert polygons overlap, IDs reset, and what you actually need to store to avoid duplicate notifications.
WeatherAPI’s condition codes can flip between when a forecast is issued and when that hour arrives. Here’s why, and how to build around it.
WeatherAPI’s daily avgtemp_c, maxtemp_c, and mintemp_c aren’t raw observations — here’s exactly how they’re derived and where they silently go wrong.
WeatherAPI condition codes behave differently at night than during the day — here’s why, how we map METAR data to codes, and what it means for your app logic.
Absolute pressure tells you where you are. Pressure tendency tells you where you’re going. Here’s how to derive and use it from WeatherAPI hourly data.
