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).

Day and Night Pictograms

Day and night pictograms show the weather condition for a period of one or three hour values during the day and night. They contain more detailed descriptions of weather conditions than the iday pictograms which represent a daily total of weather conditions.

iday Pictograms

iday pictograms show a summary of the daily weather condition. They are used in the API data feeds. The data feeds for 7 days forecasts use all the 17 iday picto- codes, the data feeds for 14 days use only the first 11 iday pictocodes. The json data feed also uses the 17 iday pictocodes.

01_iday1Sunny, cloudless sky
02_iday2Sunny and few clouds
03_iday3Partly cloudy
06_iday6Overcast with rain
07_iday7Mixed with showers
08_iday8Showers, thunderstorms likely
09_iday9Overcast with snow
10_iday10Mixed with snow showers
11_iday11Mostly cloudy with a mixture of snow and rain
12_iday12Overcast with light rain
13_iday13Overcast with light snow
14_iday14Mostly cloudy with rain
15_iday15Mostly cloudy with snow
16_iday16Mostly cloudy with light rain
17_iday17Mostly cloudy with light snow

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).


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.
