Simple weather – built on four Nordic institutes.
Nordic Weather makes weather simple. We weigh together forecasts from SMHI, YR/MET, DMI and FMI for you and show one clear answer – so you don't have to open four apps and interpret radar maps yourself. All the accuracy, none of the hassle.
Why four sources – and not one?
No single forecast model is best everywhere. We weigh them together.
Each meteorological institute trains its models on its own region. SMHI is strongest along the Swedish coast; YR/MET has an undeniable advantage in the Norwegian fjords and mountains; DMI dominates marine Denmark and the Baltic Sea; FMI has the best resolution in the Finnish archipelago.
By continuously comparing the forecasts against measured weather, we can weight the sources according to historical accuracy for your specific location. In other words, you always get the forecast that statistically has been most accurate where you're standing.
Fewer misses, less noise
Combining models smooths out deviations and catches cases where a single model is systematically wrong.
Fresh data, every 15 minutes
New model runs are fetched as soon as the institutes publish them – without you having to refresh manually.
The right model for the right place
We weight the sources by how well they have matched your specific town over the last 30 days.
How it works
From raw model runs to a forecast in your pocket.
We fetch new forecast runs from four institutes, normalise them to a common time resolution and project each point onto the same grid. Then the models are weighted based on each location's historical accuracy – a process that runs 96 times per day per location.
For the user, only the result is noticeable: a clear forecast, a probability, and – when meteorologically justified – a deviation notice telling you that the models don't agree.
