Open-Meteo

Look up the weather anywhere in the world through Open-Meteo's keyless API, across every dataset it publishes. Current conditions, forecasts by the 15 minutes, the hour and the day out to 16 days, and measured weather back to 1940. Ensemble forecasts that say how confident the outlook is, seasonal forecasts months ahead, and climate projections to 2050. Air quality and pollen, marine waves and swell, river discharge for flood watches, satellite measured solar irradiance, and ground elevation. Plus the archive of past forecasts, single model runs, and a geocoder for turning a place name into coordinates. No account or API key required.

Actions

Action	What it does
Compare forecast runs	See how the forecast for each hour has moved as that hour drew closer.
Get 15 minute forecast	Get a forecast in 15 minute steps instead of whole hours, for the next few hours or the next few days.
Get a single model run	Read one named run of one weather model exactly as it was issued.
Get air quality	Get air-quality indices and pollutant levels for a place: European and US AQI, particulates, gases, dust, UV index, and (in Europe) pollen, now and, optionally, hour by hour.
Get climate projection	Read downscaled IPCC climate model output for any date from 1950 to 2050, at a resolution of around 25 km.
Get current weather	Get current conditions for a place or an exact coordinate: temperature, feels-like, humidity, precipitation, wind, cloud cover, and a readable description of the weather code.
Get daily forecast	Get a day-by-day forecast for up to 16 days: highs and lows, precipitation totals and chance, wind, UV, and sunrise and sunset, returned as one row per day.
Get elevation	Look up how high the ground is at a place, or at up to 100 coordinates in one call.
Get ensemble forecast	Run the forecast dozens of times over from slightly different starting conditions and get back how far the runs disagree.
Get historical weather	Read the weather that actually happened over a past date range, from Open-Meteo's archive of reanalysis data going back to 1940.
Get hourly forecast	Get an hour-by-hour forecast for up to 16 days, returned as one row per hour so a workflow can loop over the timesteps.
Get location details	Look up one place by the id that a search returned, and get the fuller record: the postcodes it covers, the whole chain of administrative areas it sits in, its elevation, time zone and population.
Get marine forecast	Get sea conditions for a point on the water: wave height, direction and period, wind waves and swell separately, ocean currents, and sea surface temperature, now and by the hour and the day.
Get past forecast	Read the forecast that was being issued on a past date, from the archive of model output kept since 2021.
Get river discharge	Get the daily flow of the river nearest a point, in cubic metres per second, for up to a year ahead and three months back.
Get seasonal forecast	Look months ahead, out to about seven, with ECMWF's seasonal forecast.
Get solar radiation	Read solar irradiance as weather satellites actually measured it, rather than as a weather model predicted it, going back as far as 1983.
Search locations	Search the GeoNames database for places matching a name and get back their coordinates, elevation, time zone, region, and population.

Compare forecast runs

See how the forecast for each hour has moved as that hour drew closer. For every hour it returns today's forecast beside the forecasts issued one, two and more days ago, plus a drift figure per variable: how much the outlook has shifted on average. Use it to tell a settling forecast from a wobbling one before committing to an outdoor booking, a delivery slot or a shutdown.

Get a single model run

Read one named run of one weather model exactly as it was issued. Every other forecast action answers with the freshest data available for each hour, stitched across runs; this one pins a single computation, so the whole series is internally consistent.

Get climate projection

Read downscaled IPCC climate model output for any date from 1950 to 2050, at a resolution of around 25 km.

Get elevation

Look up how high the ground is at a place, or at up to 100 coordinates in one call. Heights come from the Copernicus digital elevation model on a 90 metre grid, in metres above sea level, and describe the terrain rather than anything standing on it. Paste a column of coordinates from a spreadsheet to profile a route or rank a list of sites.

Get ensemble forecast

Run the forecast dozens of times over from slightly different starting conditions and get back how far the runs disagree. Where the members agree the forecast is confident; where they scatter it is not, which is the difference between 'it will rain' and 'it might'. Each row gives the lowest, highest and mean member value per variable, so a workflow can act on the confidence rather than only on the headline number.

Get marine forecast

Get sea conditions for a point on the water: wave height, direction and period, wind waves and swell separately, ocean currents, and sea surface temperature, now and by the hour and the day. The wave models only cover open water, so a point inland comes back as an error saying so rather than as a row of blanks.

Get past forecast

Read the forecast that was being issued on a past date, from the archive of model output kept since 2021.

Get seasonal forecast

Look months ahead, out to about seven, with ECMWF's seasonal forecast. This answers a different question from a daily forecast: not what the weather will be on a given day, but how a whole week or month is leaning against its own long run normal. The anomaly variables carry that lean, which is what a planting date, a heating budget or a stock forecast turns on.

Get solar radiation

Read solar irradiance as weather satellites actually measured it, rather than as a weather model predicted it, going back as far as 1983. This is the number a solar yield or panel performance calculation wants. Set the tilt and the compass bearing of an array to get the irradiance falling on the panels rather than on flat ground.

Inputs

Locationlocationtext: Place name to look up, for example 'Berlin' or 'Springfield, Illinois'. The closest match is used. Leave blank if you are providing latitude and longitude instead.
Latitudelatitudenumber: Latitude of the location (-90 to 90). Use with longitude instead of a place name for an exact point.From -90 to 90.
Longitudelongitudenumber: Longitude of the location (-180 to 180). Use with latitude instead of a place name for an exact point. Locations in the Americas take a negative longitude.From -180 to 180.
Hourly variablesvariablestext: Which irradiance readings to return hour by hour.One or more of: shortwave_radiation (Global horizontal irradiance (GHI)), direct_radiation (Direct horizontal irradiance), diffuse_radiation (Diffuse horizontal irradiance (DHI)), direct_normal_irradiance (Direct normal irradiance (DNI)), global_tilted_irradiance (Global tilted irradiance (GTI)), shortwave_radiation_clear_sky (Clear sky shortwave radiation), terrestrial_radiation (Terrestrial radiation), sunshine_duration (Sunshine duration), is_day (Is day or night). Default: ["shortwave_radiation", "direct_radiation", "diffuse_radiation", "direct_normal_irradiance"].
Daily variablesdaily_variablestext: Which readings to total or summarise per day.One or more of: shortwave_radiation_sum (Shortwave radiation sum), sunshine_duration (Sunshine duration), daylight_duration (Daylight duration), sunrise, sunset.
Additional variablesadditional_variablestext: Comma-separated Open-Meteo variable names to request on top of the ones ticked above, for example 'soil_temperature_0cm' or 'temperature_850hPa'. See the Open-Meteo docs for the full list.
Start datestart_datetext: First day to return, as YYYY-MM-DD. Use with an end date to read a fixed past range instead of a window around today.
End dateend_datetext: Last day to return, as YYYY-MM-DD.
Forecast daysforecast_daysnumber: How many days ahead to forecast, from 1 to 16. Defaults to 7.From 1 to 16. Default: 7.
Past dayspast_daysnumber: How many days of already-issued forecasts to prepend, from 0 to 92. Defaults to 0. For measured weather further back, use the 'Get historical weather' action instead.From 0 to 92. Default: 0.
Panel tilttiltnumber: Angle of the panels from horizontal, 0 to 90 degrees. 0 is flat. Needed for the tilted irradiance variable.From 0 to 90. Default: 0.
Panel bearingazimuthnumber: Compass bearing the panels face, 0 to 360 degrees, where 0 is south, 90 is west and 270 is east.From 0 to 360. Default: 0.
Satellitesmodelstext: Which satellite to read. Leave blank to let Open-Meteo pick whichever one watches the location. Each watches its own part of the globe and its own span of years.One or more of: satellite_radiation_seamless (Whichever covers the location), eumetsat_sarah3 (EUMETSAT SARAH3 (Europe, from 1983)), eumetsat_msg (EUMETSAT MSG (Europe and Africa)), eumetsat_iodc (EUMETSAT IODC (Indian Ocean)), jma_jaxa_himawari (JMA JAXA Himawari (Asia Pacific)).
Time steptemporal_resolutiontext: How closely spaced the rows are. 'Native' keeps whatever the model produces. The others resample to that many hours, which is a way to cut a long series down to a readable size.One of: native (As the model produces it), hourly_1 (Every hour), hourly_3 (Every 3 hours), hourly_6 (Every 6 hours). Default: native.
Time zonetimezonetext: Time zone the timestamps are returned in, as a time-zone database name such as Europe/Berlin. Defaults to 'auto', which uses the local time zone of the location: the right choice for daily rows, which would otherwise be split across the wrong days.Default: auto.

Outputs

countrytext: Country of the resolved place
dailyobject: One row per timestep, each carrying every requested variable, plus the units the values are in
elevationnumber: Elevation of the grid-cell, in metres above sea level
hourlyobject: One row per timestep, each carrying every requested variable, plus the units the values are in
latitudenumber: Latitude of the weather grid-cell used
locationtext: Resolved place name, or empty when coordinates were given
longitudenumber: Longitude of the weather grid-cell used
timezonetext: Time zone the timestamps are in, e.g. 'Europe/Berlin'
timezone_abbreviationtext: Abbreviation of that time zone, e.g. 'CEST'
utc_offset_secondsnumber: Offset of that time zone from UTC, in seconds
