  • Local days, 2016–2025, every year weighted equally. Each weekly chart averages its own seven days, without smoothing.
  • Shading shows the 10th–90th percentile of past days, not forecast confidence.
  • A rain day has at least 1 mm, snow included. The last weekly period has eight days.
  • Wind is the average daytime (10:00–18:00) maximum, not gusts. Daylight is calculated from latitude. Missing readings stay blank.
  • Mugginess (dew point) comes from the original daily summaries, on UTC days.
  • The live two-week forecast comes from the Open-Meteo Weather Forecast API. The Weather Index does not use it.
