The pressure seems wrong

Dirk Tempelaar Oct 19, 2016 04:23PM UTC


I'm using the API, but the data seems wrong.

For example, for my city Hoek van Holland (ID 2754007), Netherlands. I got pressure as 1029.21 hPa by the API.
However, the real pressure at this time would be around 1014 by some other forecast.

Thanks by advance,

I am experiencing the same error with several parameters in The Hague (Den haag), the Netherlands
-The main website ( shows different values in the left table (which are correct) and on the right part of the screen. Are two different sources used here?
-Comparing the values with official values from the KNMI (Dutch Meteorological Office:, the values differ in:
Pressure: 1024 hPa (KNMI) vs 1040 hPa (Openweathermap)
Humidity: 91% (KNMI) vs 100% (Openweathermap)
Wind speed:3 m/s (KNMI) vs 4.5 m/s (Openweathermap).

Any ideas where the differences are coming from?

Kind regards,
