DATA SOURCE

Open-Meteo weather forecast APIs use weather models from multiple national
weather providers. For each location worldwide, the best models will be combined
to provide the best possible forecast.

Weather models cover different geographic areas at different resolutions and
provide different weather variables. Depending on the model, data have been
interpolated to hourly values or not all weather variables are available. With
the drop down Weather models (just below the hourly variables), you can select
and compare individual weather models.

You can find the update timings in the model updates documentation. Weather

API DOCUMENTATION

The API endpoint /v1/forecast accepts a geographical coordinate, a list of
weather variables and responds with a JSON hourly weather forecast for 7 days.
Time always starts at 0:00 today and contains 168 hours. If &forecast_days=16 is
set, up to 16 days of forecast can be returned. All URL parameters are listed
below:

Parameter Format Required Default Description latitude, longitude Floating point
Yes Geographical WGS84 coordinates of the location. Multiple coordinates can be
comma separated. E.g. &latitude=52.52,48.85&longitude=13.41,2.35. To return data
for multiple locations the JSON output changes to a list of structures. CSV and
XLSX formats add a column location_id. elevation Floating point No The elevation
used for statistical downscaling. Per default, a 90 meter digital elevation
model is used. You can manually set the elevation to correctly match mountain
peaks. If &elevation=nan is specified, downscaling will be disabled and the API
uses the average grid-cell height. For multiple locations, elevation can also be
comma separated. hourly String array No A list of weather variables which should
be returned. Values can be comma separated, or multiple &hourly= parameter in
the URL can be used. daily String array No A list of daily weather variable
aggregations which should be returned. Values can be comma separated, or
multiple &daily= parameter in the URL can be used. If daily weather variables
are specified, parameter timezone is required. current String array No A list of
weather variables to get current conditions. temperature_unit String No celsius
If fahrenheit is set, all temperature values are converted to Fahrenheit.
wind_speed_unit String No kmh Other wind speed speed units: ms, mph and kn
precipitation_unit String No mm Other precipitation amount units: inch
timeformat String No iso8601 If format unixtime is selected, all time values are
returned in UNIX epoch time in seconds. Please note that all timestamp are in
GMT+0! For daily values with unix timestamps, please apply utc_offset_seconds
again to get the correct date. timezone String No GMT If timezone is set, all
timestamps are returned as local-time and data is returned starting at 00:00
local-time. Any time zone name from the time zone database is supported. If auto
is set as a time zone, the coordinates will be automatically resolved to the
local time zone. For multiple coordinates, a comma separated list of timezones
can be specified. past_days Integer (0-92) No 0 If past_days is set, yesterday
or the day before yesterday data are also returned. forecast_days Integer (0-16)

possible. forecast_hours
forecast_minutely_15
past_hours
past_minutely_15 Integer (>0) No Similar to forecast_days, the number of
timesteps of hourly and 15-minutely data can controlled. Instead of using the
current day as a reference, the current hour or the current 15-minute time-step
is used. start_date
end_date String (yyyy-mm-dd) No The time interval to get weather data. A day
must be specified as an ISO8601 date (e.g. 2022-06-30). start_hour
end_hour

weather models. Per default, the best suitable weather models will be combined.
cell_selection String No land Set a preference how grid-cells are selected. The
default land finds a suitable grid-cell on land with similar elevation to the
requested coordinates using a 90-meter digital elevation model. sea prefers
grid-cells on sea. nearest selects the nearest possible grid-cell. apikey String

HOURLY PARAMETER DEFINITION

The parameter &hourly= accepts the following values. Most weather variables are
given as an instantaneous value for the indicated hour. Some variables like
precipitation are calculated from the preceding hour as an average or sum.

Variable Valid time Unit Description temperature_2m Instant °C (°F) Air
temperature at 2 meters above ground relative_humidity_2m Instant % Relative
humidity at 2 meters above ground dew_point_2m Instant °C (°F) Dew point

Apparent temperature is the perceived feels-like temperature combining wind
chill factor, relative humidity and solar radiation pressure_msl

(msl) or pressure at surface. Typically pressure on mean sea level is used in
meteorology. Surface pressure gets lower with increasing elevation. cloud_cover

Preceding hour mean W/m² Shortwave solar radiation as average of the preceding
hour. This is equal to the total global horizontal irradiation direct_radiation
direct_normal_irradiance Preceding hour mean W/m² Direct solar radiation as
average of the preceding hour on the horizontal plane and the normal plane
(perpendicular to the sun) diffuse_radiation Preceding hour mean W/m² Diffuse
solar radiation as average of the preceding hour global_tilted_irradiance
Preceding hour mean W/m² Total radiation received on a tilted pane as average of
the preceding hour. The calculation is assuming a fixed albedo of 20% and in
isotropic sky. Please specify tilt and azimuth parameter. Tilt ranges from 0° to
90° and is typically around 45°. Azimuth should be close to 0° (0° south, -90°
east, 90° west). If azimuth is set to "nan", the calculation assumes a
horizontal tracker. If tilt is set to "nan", it is assumed that the panel has a
vertical tracker. If both are set to "nan", a bi-axial tracker is assumed.

this location. Available soil water is considered. 1 mm evapotranspiration per
hour equals 1 liter of water per spare meter. et0_fao_evapotranspiration
Preceding hour sum mm (inch) ET₀ Reference Evapotranspiration of a well watered
grass field. Based on FAO-56 Penman-Monteith equations ET₀ is calculated from

assumed. ET₀ is commonly used to estimate the required irrigation for plants.

snow) sum of the preceding hour snowfall Preceding hour sum cm (inch) Snowfall

15-MINUTELY PARAMETER DEFINITION

The parameter &minutely_15= can be used to get 15-minutely data. This data is

regions data is interpolated from 1-hourly to 15-minutely.

15-minutely data can be requested for other weather variables that are available
for hourly data, but will use interpolation.

PRESSURE LEVEL VARIABLES

Pressure level variables do not have fixed altitudes. Altitude varies with
atmospheric pressure. 1000 hPa is roughly between 60 and 160 meters above sea
level. Estimated altitudes are given below. Altitudes are in meters above sea
level (not above ground). For precise altitudes, geopotential_height can be
used.
