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.
humidity_pct alone tells you almost nothing about water demand. Here’s how to derive ET₀ estimates from WeatherAPI’s hourly fields — and where the math breaks down.
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.
Condition codes won’t catch a frost before it forms. Here’s how to combine dewpoint, temp, and cloud cover fields to build an early frost alert that actually works.
Dew point tells you more about outdoor discomfort than humidity does. Here’s how to detect the exact forecast hour it crosses into oppressive territory.
Build a nuanced thermal comfort score for outdoor apps using temp, humidity, wind, and solar radiation from WeatherAPI’s hourly forecast endpoint.
Condition codes flag thunderstorms too late for most apps. Here’s how to use pressure trend, dewpoint, and humidity together to catch risk early.
WeatherAPI doesn’t return freezing level altitude directly. Here’s the exact method to derive it from temp, dew point, and lapse rate — with real code.
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.
