Pictograms

Pictograms​

Weather conditions are graphically summarised by pictograms. These show sunshine, clouds, precipitation type, intensity and thunderstorms for the time period referenced in the forecast. A detailed symbol description is shown below. Pictograms are used in overviews like on the start page and in meteograms. The period for which the pictogram is effective is printed above or below. An hour indicates the end of the interval (e.g. a 3-hour pictogram marked 11:00 includes the forecast from 8:01 until 11:00, and the following 3-hour pictogram marked 14:00 includes the forecast from 11:01 until 14:00).

Daily Pictograms​

The Daily pictograms show a summary of daily weather conditions and are used in the API data feeds. The data feeds for 7-day forecasts use all the 25 Daily pictocodes, the data feeds for 14 days use only the first 16 Daily pictocodes and the json data feed uses 17 of the Daily pictocodes.

Day and Night / Detailed Pictograms​

Day and Night / Detailed pictograms show the weather conditions based on the values for a period of one or three hours during the day and night. They contain more detailed descriptions of weather conditions than the daily pictograms which represent a daily total of weather conditions.

Calculation of the Pictograms​

meteoblue pictograms show the most likely weather conditions for a location, based on a very detailed analysis of local forecast (black squares) in an area (yellow square). The area considered is within 20-30 km of the chosen centre point location (e.g. green points: Évian in Southeast and Morges in Northwest of square).

How_the_weather_pictograms_are_calculated

For each point, a different pictogram is calculated. Main factors considered are:

  • cloud cover: average of all cloud cover in the area.
  • precipitation intensity: average of precipitation for the chosen location.
  • precipitation type: prevailing precipitation for the chosen location.
  • wind (if displayed): average or maximum wind for the chosen location.

Pictogram calculation combines the regional and local forecasts to match our perception: sunshine and cloudiness are perceived regionally, whereas precipitation, wind and temperature are perceived locally.
