Site specific forecasts for over 5,000 sites in the UK, including airports, major landmarks and beaches. Each site has the following weather forecast data available for it in 3-hourly intervals out to five days:

  • Wind direction (16 point compass)
  • Wind speed (mph)
  • Screen temperature (degrees Celsius)
  • Weather Type (weather ID)
  • Visibility (code)
  • Screen relative humidity (%)
  • Wind gust (mph)
  • Feels like temperature (degrees Celsius)

Met Office provides a restricted API to the forecast data. restrictions registration and used under licence. Data is provided in XML and JSON. Data is not available for bulk download.

HOWEVER the Cabinet Office provides an API to all of the data, with unlimited access: API on Azure Marketplace. The only requirement is that you register, which is reasonable when the Met Office data is about 20GB per day. Since there is no size restriction with this API, beyond technical constraints, you can easily download what you want, so that should be considered easy bulk access.

Some historic data is available for download but other historic data must be purchased.
