Weather Forecast 85% open

Great Britain

What data is expected?

3-day forecasts of temperature, precipitation and wind. Forecasts have to be provided for several regions in the country. Short-term weather forecasts are relevant for the general public to plan activities, while also being reliable. See our methodology section for more information.

  • Temperature extremes
  • Temperature average
  • Wind speed
  • Wind direction
  • Precipitation Amount
  • Precipitation Probability
  • Forecast for current day and four following days

How open is the data?

The data source provides "screen temperature" (the ambient temperature without the effect of wind chill or heat from the sun) and doesn't seem to provide separate data for averages vs extremes. The data source provides probability of precipitation based on precipitation of at lease 0.1mm but does not seem to estimate amounts. A Met Office tutorial indicates the DataPoint service can now be used to download "a complete list of the forecasts for every location in the UK at each available timestep" in either XML or JSON format. I have interpreted that as meaning the whole dataset is downloadable at once. (This obviates the need to revisit last year's debate about whether the separate API on Azure Marketplace really supplies bulk data.) Availability of the data only in machine-readable formats via an API imposes a technical learning curve and therefore reduces the general accessibility of the data. Met Office could for example make the data more accessible by publishing a daily CSV extract of the dataset.

The submission is valid. Precipitation amount was added as a characteristics. The dataset describes it as "Weather Type" (alongside other weather types like sunny, clouded, etc.) Thank you, Owen Boswarva, for contributing to the Global Open Data Index.

Data location - DataPoint UK 3-hourly site-specific forecast. Described as "a quality controlled forecast out to 5 days for more than 5,000 locations."
