Rhineland-Palatinate

Pick one of the 9 cities above to open a page where you put any two time periods side by side. Temperature, sunshine hours, precipitation, and peak wind all come as daily and monthly means. If you would rather see several years of the same month next to each other, follow the climate-trend link on any city card. It shows up to ten years at a glance.

To get a first sense of Rhineland-Palatinate, start with the most populous city on the list. The weather data for each city is drawn from a tight grid, so the contrast between coast, plain, and low mountain range in the region is visible straight from the numbers. If extremes are your focus, heat waves, cold snaps, or heavy-rain events, compare the same calendar window between two different years.

All values come from the ECMWF ERA5 reanalysis dataset, delivered via the Open-Meteo archive API. ERA5 blends global satellite and station measurements into a gap-free grid that serves the same variables for every city in Rhineland-Palatinate: daily high and low temperature, sunshine duration, total precipitation, and the maximum wind speed at ten metres above ground. The time series reaches back to 1940, so historical heatwaves and cold winters compare cleanly with the current state.

Because the data is reanalysed, meaning retrospectively calibrated with every available observation, the values stay consistent from long-ago years into the recent past. That makes comparisons across Rhineland-Palatinate fair: numbers from 1970 and from 2025 come from the same product, only with different observation densities in the background. The comparison is free and ad-free. For details on a single city, just open its card above.
