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.
Processing HRRR and GFS GRIB2 files efficiently isn’t just about parsing — chunk size and field selection decisions dominate real-world ingestion performance.
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 returns wind speed at 10m reference height. Here’s why that causes real discrepancies and how to correct for it in your application.
Burning API quota on retries and duplicate calls is easy to avoid. Here’s how to build a request queue that respects rate limits and protects your monthly cap.
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.
Build a solar and wind energy output estimator using WeatherAPI’s hourly forecast fields. Real field names, formulas, and caveats for developers.
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.
