Weather Insight is a real competitive advantage


Spire Forecast API

Spire Forecast API is an easy to use API that offers access to our state of the art weather forecast data. Spire’s APIs are developer-friendly, so you can plug and play effortlessly adding new data and key insights into your systems. In addition to the complete documentation, we also offer outstanding support to help you start ingesting data and building apps quickly.

More valuable forecasts

50+ high precision weather variables available anywhere on the planet in 1/8th-degree resolution (approx. 12km).

Make better decisions

The forecasts are output hourly for 24 hours and every 6 hours for up to 7 days.

Quick and easy to use

Integrate advanced weather data, available in JSON or GRIB2 formats, directly into analytics platform easily and quickly.

Spire’s offer also includes hindcast. Contact us directly for more details.

Spire Forecast API is organized into specific bundles. Each bundle groups together weather variables that are needed for a specific domain. Bundling data in this way allows us to tailor specific types of data that are industry specific for your business.


Standard Bundle

The most commonly used weather surface variables:

  • Temperature
  • Relative humidity
  • Dewpoint temperature
  • Wind speed and direction (as u-wind/v-wind components)
  • Mean sea-level pressure
  • Accumulated precipitation
  • Wind gust speed
  • Maximum and Minimum temperature


Maritime Bundle

The Maritime bundle provides the following oceanographic forecasts at sea level:

  • Sea Surface Temperature
  • Ocean Currents speed and direction
  • Total waves (wind and swell combined):
    • Significant Wave Height
    • Mean Wave Direction
    • Mean Wave Period


Maritime Wave Bundle

The Maritime Wave bundle provides the following oceanographic forecasts at sea level:

  • Significant Wind Wave Height
  • Mean Wind Wave Direction
  • Mean Wind Wave Period
  • Significant Total Swell Wave Height
  • Mean Total Swell Wave Direction
  • Mean Total Swell Wave Period


Upper air Bundle

The Upper Air bundle provides forecasts at multiple Isobaric levels:

  • Geopotential height
  • Temperature
  • Wind speed and direction (as u-wind/v-wind components)
  • Relative humidity
  • Vertical velocity
  • Absolute vorticity
  • Cloud water mixing ratio
  • Cloud ice mixing ratio


Thunderstorm Bundle

For thunderstorm conditions the following information is available:

  • Convective Available Potential Energy at whole atmosphere
  • Convective Inhibition at whole atmosphere

  • Storm motion (northward component)
  • 0-6 km shear vector (eastward component)
  • 0-6 km shear vector (northward component)
  • Precipitable Water


Aviation Bundle

The aviation bundle brings forecast to flight levels:

  • Air temperature
  • Relative humidity
  • The eastward-component of the horizontal wind
  • The northward-component of the horizontal wind
  • The horizontal surface visibility
  • The height (above sea level) where the maximum wind speed is found
  • The eastward component of the maximum horizontal wind
  • The northward component of the maximum horizontal wind
  • Potential severity of clear-air turbulence associated with wind shear (not due to mountain waves or convection)
  • Potential for aircraft icing


Agricultural Bundle

For agriculture or soil the following surface level forecast is available:

  • Skin (surface) temperature
  • Specific humidity
  • Soil moisture (0-10 cm, 10-40 cm, 40-100 cm, 100-200 cm)
  • Soil temperature (0-10 cm, 10-40 cm, 40-100 cm, 100-200 cm)
  • Latent heat flux
  • Sensible heat flux
  • Incoming shortwave radiation from above
  • Incoming longwave radiation from above
  • Outgoing longwave radiation from the surface
  • Outgoing shortwave radiation from the surface
  • Outgoing longwave radiation from the top of the atmosphere


Renewable Energy Bundle

A bundle dedicated to wind and solar power with:

  • The eastward and northward components of wind at 80m
  • The eastward and northward components of wind at 100m
  • The eastward and northward components of wind at 120m
