IMGW-PIB Polish Weather Stations & Open Data Explorer
Explore observations across Poland
Discover weather stations in Poland and compare observations published by the Institute of Meteorology and Water Management – National Research Institute (IMGW-PIB). Choose hourly, daily or monthly resolution, filter the network by date coverage, select a station, and inspect the available values on maps, plots or a data table.
IMGW-PIB produces and publishes the source records. Climate Explorer independently retrieves selected public files, translates column labels, and presents the observations; it is not affiliated with or endorsed by IMGW-PIB.
Click the Maximize button in the top-right corner of the explorer frame to expand to Full Screen mode for optimal map and chart visibility. Click it again or press Esc to exit.
Dataset facts
- Official source
- Coverage
-
Polish station observations at hourly, daily and monthly resolutions. Explorer metadata contains station-dependent periods from January 1869 onward, but availability and continuity vary by station type and resolution.
- Update frequency
-
IMGW-PIB documents archive publication around the fifth working day after month-end for synoptic-station files. Climatological and observer-operated precipitation-station files can follow a longer schedule, around the tenth working day of the second following month.
- Licence
-
Reuse is governed by the IMGW-PIB public-data terms. The terms require the source statement “Źródłem pochodzenia danych jest Instytut Meteorologii i Gospodarki Wodnej – Państwowy Instytut Badawczy”. When data are transformed, they also require “Dane Instytutu Meteorologii i Gospodarki Wodnej – Państwowego Instytutu Badawczego zostały przetworzone”.
- Important limitation
-
Station metadata, available variables and record length vary. Current-year files may be corrected and replaced, and the provider notes that some data can be unverified when that is the only version available at publication time.
Custom Climate Dashboards & Data Pipelines
Climate Explorer engineers custom meteorological solutions tailored to research institutions, public agencies, and enterprise operations. We build high-performance web applications and interactive dashboards using Next.js, React, Node.js, DuckDB, Shiny, and Python FastAPI, alongside automated data scraping & ingestion pipelines, historical observation archives, and specialized spatial homogenization & extreme-event analyses.
What you can compare
- Hourly observations: Examine within-day temperature, humidity, wind, pressure, cloud, visibility, precipitation and snow fields when supplied by the station and source product.
- Daily observations: Compare daily temperatures, precipitation, sunshine, snow and weather-phenomenon durations over event or seasonal windows.
- Monthly observations: Review provider-supplied monthly temperature and precipitation statistics, sunshine, snow and event-day counts over longer periods.
The same variables are not available for every station. Stations Info shows the station identifier, name, WMO identifier, type, represented parameter groups, coordinates, elevation and metadata period before a dataset is loaded.
Read station and status fields carefully
These are point observations, not gridded estimates or a national average. Elevation, urban surroundings, Baltic exposure, lowland terrain and mountain location can make nearby stations differ. A selected series describes its observing site and should not automatically be generalized to a voivodeship or to Poland as a whole.
The explorer displays Synoptic and Climatological classifications from its station catalogue. They help identify the represented product family, but they do not establish present staffing, current instruments or continuous availability of every parameter.
IMGW source files pair many measurement columns with status fields. In the provider documentation, a blank status accompanies a reported value, 8 means no measurement, and 9 means no phenomenon. A missing measurement is not zero. The interface translates these statuses for readability, but the official format descriptions remain authoritative.
For cross-border near-real-time comparison, use the EuroMeteo hourly station explorer. For selection, field interpretation, Excel export and official ZIP/CSV access, read the IMGW-PIB observation and download guide. For the wider policy and access context, read the evidence-led article on Europe’s open weather-data portals.

Frequently Asked Questions
Which IMGW-PIB time resolutions can I explore?
The interface provides hourly, daily and monthly modes. Station and variable availability depends on the selected resolution and period.
Does a missing measurement mean zero?
No. IMGW-PIB documents status 8 as no measurement and status 9 as no phenomenon. Only the latter can appropriately become zero for the associated phenomenon when the source field is otherwise empty.
Are the displayed hourly timestamps guaranteed to be UTC?
No. The source format descriptions expose year, month, day and hour fields but do not state a universal time zone. Climate Explorer creates a machine-readable timestamp for plotting; verify the provider’s intended clock basis before combining hourly data with another time system.
Does Climate Explorer replace the official archive?
No. Climate Explorer provides an independent viewing and workbook-export layer. IMGW-PIB remains the authoritative source for files, formats, status codes, corrections and reuse conditions.
