Direct temperature comparison for Berlin, Hamburg and Munich in MeteoDeck
Several temperature curves on one shared timeline.

Temperature

Shows the hourly temperature trend for each place. Apparent temperature is displayed alongside air temperature to account for the effect of wind, humidity and radiation.

Hourly temperature and apparent temperature curves in MeteoDeck
Air temperature and apparent temperature for each place.

Sunshine

Visualises forecast sunshine duration by hour. This makes it easy to find longer sunny periods and see which location is expected to have the best conditions.

Hourly sunshine duration for several cities in MeteoDeck
Yellow bars show the expected sunshine duration.

Precipitation

Displays hourly precipitation amount and probability. The two values answer different questions: how likely rain is and how much is expected to fall.

Precipitation amount and rain probability in MeteoDeck
Rain amount as bars and probability as a line.

Clouds

Shows cloud cover as a percentage throughout the day. Low values indicate clearer skies, while high values represent heavy cloud or a fully overcast sky.

Percentage cloud cover throughout the day in MeteoDeck
Colour levels distinguish clear skies from heavy cloud.

Wind

03 FORECAST MODELS

Best Match, ICON, ECMWF and GFS

Best Match

Automatically selects a locally suitable forecast with the best available spatial resolution.

DWD ICON

The German Weather Service forecast system is particularly useful for Germany and Europe.

ECMWF IFS

A global forecast model from the European Centre for Medium-Range Weather Forecasts.

NOAA GFS

A global forecast model from the US National Oceanic and Atmospheric Administration.

Different models can produce different results. Forecasts are model-based estimates, not guarantees, and do not replace official severe-weather warnings.
