How does the weather forecast work?

The forecast at Meteo Info Online is not produced from generic text, but from weather input data, caching rules and our own output layer for localities, regions and thematic centers. The last major update to the methodology was made on March 8, 2026.

How the forecast is generated

For each locality, the current state, the hourly trend and the multi-day trends are loaded from the data flow. These values are then converted into clearly defined blocks for locality, region and thematic-access pages.

What affects accuracy

Short-term trends are usually more reliable than multi-day forecasts. Topography, the density of the measurement network, the quality of the model and the dynamics of the weather situation directly affect accuracy.

How we manage timeliness

A caching and freshness logic is applied over the live data. The data is updated every four hours; when it is too old, incomplete or cannot be clearly assigned to a locality, a module is limited, flagged or simply not published as fully live.
