Historical charts

Use Historical Charts to review trends and extremes by Day, Month, and Year.

Choose a period

Use the toolbar period picker:

  • Today, Yesterday, One Week Ago, One Month Ago, One Year Ago for daily charts, displaying observation-level samples.
  • This Month, Last Month for monthly summaries.
  • This Year, Last Year for yearly summaries.

On macOS, hover over a chart to inspect values. On iOS, drag across a chart to inspect values.

Available charts

  • Temperature, Humidity, Dew Point, Heat Index, Wet Bulb
  • Rain Rate, Rain Accumulation, Evapotranspiration
  • Wind, Wind Gust, Wind Direction Rose, Wind Gust Direction Rose
  • Pressure
  • Solar Irradiance, UV Index
  • Air Quality: PM1, PM2.5, PM10, AQI Value

Available metrics depend on your provider and installed sensors.

If charts are empty or partial

This usually means one of these conditions:

  • No data exists for that period.
  • The metric is not available from your provider or sensors.
  • History is incomplete for the selected window.
  • A download, import, or summary recalculation is still running.

Run Download and then Recalculate Summaries in Data maintenance if needed.

If charts stay empty, use Troubleshooting.
