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 returns wind speed at 10m reference height. Here’s why that causes real discrepancies and how to correct for it in your application.
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.
GFS, NAM, and HRRR don’t update continuously. Here’s how model run schedules create a ‘dead zone’ that makes your API forecast older than you think.
Cloud cover percentage in weather APIs measures sky fraction, not ceiling height. Here’s why that breaks for mountain terrain and what to derive instead.
More API requests don’t mean fresher weather data. Here’s why model run cadence caps your real freshness ceiling, and how to poll smarter.
Condition codes tell you what’s happening, not how bad it is. Here’s how to build a real severity layer from WeatherAPI’s raw fields.
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.
