Weather variables information

  • Temperature (2m) and relative humidity (2m): Comparable to measurements at 2 meters above ground.
  • Tlak: Atmospheric air pressure adjusted to mean sea level as most commonly used for weather reports. The local pressure varies with altitude. Locations at higher elevation have a lower local atmospheric pressure.
  • Množství srážek: Total precipitation amount including rain, convective precipitation and snow. 1 mm at 10:00 is comparable to a rain-gauge measurement from 9:00-10:00.
  • Množství sněhových srážek: Fraction of total precipitation that falls as snow and is converted to cm instead of mm.
  • Celková oblačnost: Percentage of the sky covered with clouds: 50% means half of the sky is covered. 0-25% is mostly clear sky, 25-50% partly cloudy, 50-85% mostly cloudy and above 85% overcast.
  • Nízká, střední a vysoká oblačnost: Cloud cover at different altitudes. High clouds (8-15 km) like Cirrus, are less significant for total cloud cover than mid clouds (4-8 km) like Alto-Cumulus and Alto-Stratus, or low clouds (below 4 km), like Stratus, Cumulus and fog.
  • Sluneční záření: Global radiation (diffuse and direct) on a horizontal plain given in Watt per square meter.
  • Rychlost větru: Hourly average wind speeds at given altitude levels (e.g. 10 and 80 meters above ground) or pressure level (e.g. 900 hPa). Units can be selected.
  • Směr větru: Wind direction in degrees, seamlessly from 0° (wind blowing from North), 90° (East wind), 180° (South wind) and 270° (West wind) to 359°.
  • Poryvy větru: Short term wind speed turbulence in an hour. Gusts are maximum measurable wind speed and indicate the level of turbulence. They are mostly higher than regular wind speeds.


This graph allows a quick look over the data that can be downloaded. Long data series are dynamically aggregated to daily or monthly values. It automatically refreshes on changes.

You can zoom by click and drag to left or right. A click on a weather variable name in the legend below the chart hides the data series for better readability.


Časové pásmo - vyrovnání

All data will use the selected timezone. There is no automatic switching for daylight saving time. Data are either summer or winter-time. The current timezone is selected automatically. We highly recommend GMT+00 for further processing.

Hodinově / Denně

Aggregate data to daily minimum, mean, maximum and summation in CSV download. This simplifies further data analyses in external programs.


Parameter for growing degree days (GDD)

Adjust base and limit parameter for growing degree calculation. A limit-value lower than base, calculates the temperature cold sum.
