Overview

Daily forecast up to 10 days and hourly up to 96 hours for a point. MET Norway is preferred for Baltic/Nordic points, Open-Meteo (ICON-EU) elsewhere.

Authentication

Every request requires the x-api-key header. Credits used and remaining quota are returned in response headers (x-api-credits-used, x-api-remaining-credits, x-rate-limit-*).

Request

GET query.

Parameters

Name	Type	Required	Default	Options	Description
`latitude`	number	* Required	—	—	Point latitude -90..90.
`longitude`	number	* Required	—	—	Point longitude -180..180.
`granularity`	string	Optional	`daily`	`daily` `hourly` `both`	daily, hourly or both. Default daily.
`days`	integer	Optional	`10`	—	Daily forecast days 1–10. Default 10.
`hours`	integer	Optional	`96`	—	Hourly forecast hours 1–96. Default 96.
`fields`	string	Optional	—	`temp` `tmin` `tmax` `tmean` `precip` `precipprob` `snow` `wind` `windgust` `winddir` `humidity` `pressure` `cloud` `uvi` `dewpoint` `et0` `sunrise` `sunset` `daylight` `weathercode`	Comma-separated field list. All fields when empty. Valid keys are listed under Options (tmin/tmax/tmean... daily only, temp hourly only).

Response

Name	Type	Description
`granularity`	string	Granularity used.
`fromDate`	string	First daily date (daily/both).
`toDate`	string	Last daily date (daily/both).
`fromTime`	string	First hourly time UTC ISO (hourly/both).
`toTime`	string	Last hourly time UTC ISO (hourly/both).
`daysReturned`	integer	Number of daily rows returned.
`hoursReturned`	integer	Number of hourly rows returned.
`gridLatitude`	number	Latitude of the 0.1° grid corner around the request (interpolation reference).
`gridLongitude`	number	Longitude of the 0.1° grid corner.
`gridInterpolated`	boolean	true: values bilinearly blended from the 4 surrounding cells. false: single cell.
`sources`	array	Data sources that contributed: copernicus-era5-land, open-meteo, openweather, met-norway. For past days (older than about a week) Copernicus ERA5 / ERA5-Land takes precedence; UV, precipitation probability and the weather code of wet hours / days are derived from ERA5-Land variables, wind gust comes from ERA5 (0.25°); cloud cover and the weather code of dry hours / days are filled from other sources when available. At coastal / sea points ERA5-Land values come from the nearest land grid point.
`disclaimer`	string	Decision-support disclaimer and source attribution.
`daily`	array	Daily rows when granularity is daily.
`daily[].date`	string	Day YYYY-MM-DD (UTC).
`daily[].tmin`	number	Minimum temperature °C.
`daily[].tmax`	number	Maximum temperature °C.
`daily[].tmean`	number	Mean temperature °C.
`daily[].precipMm`	number	Total precipitation mm.
`daily[].snowMm`	number	Snow mm (approx. water equivalent).
`daily[].windKmh`	number	Max wind km/h.
`daily[].windGustKmh`	number	Max wind gust km/h. For past days from ERA5 (0.25° grid, daily max of end-of-hour hourly gusts); may be lower than mean wind (windKmh, 0.1° ERA5-Land). May be null.
`daily[].windDirectionDeg`	number	Dominant wind direction degrees.
`daily[].humidityPercent`	number	Mean relative humidity %.
`daily[].pressureHpa`	number	Mean pressure hPa.
`daily[].cloudPercent`	number	Mean cloud cover %. May be null.
`daily[].uvi`	number	Max UV index (forecast only).
`daily[].dewPointC`	number	Mean dew point °C.
`daily[].et0Mm`	number	Reference evapotranspiration ET0 mm (FAO-56).
`daily[].sunrise`	string	Sunrise UTC ISO.
`daily[].sunset`	string	Sunset UTC ISO.
`daily[].daylightMinutes`	integer	Daylight duration minutes.
`daily[].weatherCode`	integer	OpenWeather-style condition code (800 clear, 5xx rain ...).
`hourly`	array	Hourly rows when granularity is hourly/both.
`hourly[].time`	string	Hour UTC ISO.
`hourly[].tempC`	number	Temperature °C.
`hourly[].humidityPercent`	number	Relative humidity %.
`hourly[].windKmh`	number	Wind km/h.
`hourly[].windGustKmh`	number	Wind gust km/h (max gust over the preceding hour). May be null.
`hourly[].precipMm`	number	Precipitation in that hour mm.
`hourly[].precipProbability`	number	Precipitation probability 0–1 (when available).
`hourly[].cloudPercent`	number	Cloud cover %. May be null.
`hourly[].weatherCode`	integer	OpenWeather-style condition code.

Errors

HTTP	code	Description
`400`	`-257`	latitude/longitude missing or out of range (lat -90..90, lon -180..180).
`400`	`-258`	Invalid date parameter.
`400`	`-259`	granularity/days/hours/metric/op/comparator is invalid.
`429`	`-316`	Daily new location (cell) limit (50) reached. Previously requested locations keep working; new locations next day (UTC). Retry-After header gives seconds until end of day.
`503`	`-261`	No stored weather for this location yet. Cells were created; the collector is filling them. Retry shortly.
`401`	`-100`	x-api-key is missing, empty, malformed, inactive, banned, expired, IP-restricted, or not allowed for this API.
`429`	`-221`	Per-minute request limit exceeded. Response headers: x-rate-limit-limit, x-rate-limit-remaining, x-rate-limit-reset.
