Usage

Example:

from meteogalicia_api.interface import MeteoGalicia
meteogalicia = MeteoGalicia()
meteogalicia.get_forecast_data("32054")
meteogalicia.get_observation_data("15023")

Custom session and timeout:

import requests
from meteogalicia_api.interface import MeteoGalicia

session = requests.Session()
meteogalicia = MeteoGalicia(session=session, timeout=10)
meteogalicia.get_forecast_data("32054")

Tide forecasts are dated in Europe/Madrid, including when the caller runs in another timezone. The date field describes today's RSS item; todayDate, tomorrowDate and yesterdayDate are local calendar dates in ISO format. The tomorrowTides field contains all tides for tomorrow, while tomorrowFirstTide remains available. RSS items are selected by forecast date rather than their order in the response. Timezone rules fall back to the packaged tzdata when the host has no IANA database.

Town hall or city data methods:

meteogalicia.get_forecast_data("32054")
meteogalicia.get_hourly_forecast_data("32054")
meteogalicia.get_medium_term_forecast_data("32054")
meteogalicia.get_warnings_data("32054")
meteogalicia.get_max_warning_levels_data("32054")
meteogalicia.get_observation_data("15023")

Parameter id's are available at https://www.meteogalicia.gal/datosred/infoweb/meteo/docs/rss/JSON_Pred_Concello_es.pdf

Hourly and medium term forecasts:

Both methods return the original JSON dictionary, including the forecast wrapper. They return None if the request fails, the forecast container is missing or is not an object, or its prediction list is missing, empty or is not a list. Individual records are returned unchanged; the client does not validate every field.

• Hourly dataPredicion values use local time in Galicia (Europe/Madrid) and contain no UTC offset. The client does not convert them to UTC. Consumers must account for the local time zone and daylight saving changes.
• MeteoGalicia uses -9999 for unavailable weather values. The client preserves this sentinel; consumers should treat it as missing data, not as a temperature, probability or valid weather code.
• Medium term icoCeo1, icoCeo2 and icoCeo3 are possible sky conditions with corresponding probIcoCeo1, probIcoCeo2 and probIcoCeo3 probabilities. They are not morning, afternoon and night forecasts. Use the probabilities when choosing a representative condition.
• The medium term forecast starts after the short term forecast. The number of days and hours varies with availability; combine daily forecasts using their dates rather than assuming fixed list lengths.

data = meteogalicia.get_hourly_forecast_data("15030")
if data is not None:
    for day in data["predHoraria"]["listaPredDiaHoraria"]:
        for hour in day["listaPredHora"]:
            temperature = hour.get("tMedia")
            if temperature is not None and temperature != -9999:
                print(hour["dataPredicion"], temperature)

Official response schemas and weather codes: hourly forecast and medium term forecast.

Warning methods:

# Detailed warnings: level, alert type and validity period.
warnings = meteogalicia.get_warnings_data("15030", day=-1)

# MeteoGalicia's own maximum warning level summary.
levels = meteogalicia.get_max_warning_levels_data("15030", day=-1)

The optional day argument accepts 0 (today), 1 (tomorrow), 2 (the day after tomorrow) and -1 (all available days). Both methods return the original MeteoGalicia JSON dictionary. In both endpoints, including requests for a single day, listaDiaConcellos contains day objects with a dia field and either listaAvisosConcellos or listaNiveisMaximos. Select days by dia, not their position in the list.

if warnings is not None:
    for daily in warnings["listaDiaConcellos"]:
        print(daily["dia"], daily["listaAvisosConcellos"])

An empty daily list is a valid response: for detailed warnings it means there are no warnings for that day. Malformed responses and request failures return None.

• get_warnings_data() uses jsonAvisosConcellos.action and exposes individual warnings, including idNivel, dataAviso, dataIni, dataFin, idTipoAlerta, tipoalerta_gl and tipoalerta_es.
• get_max_warning_levels_data() uses jsonConcellosNivelMax.action and exposes MeteoGalicia's nivelMax summary (0 normal, 1 yellow, 2 orange, 3 red).

Official documentation: complete municipal warnings and maximum municipal warning level.

Configuration catalogs:

# Static municipal catalog, optionally filtered by province.
concellos = meteogalicia.get_concellos("A Coruña")

# Live MeteoGalicia station catalog, optionally filtered by province/concello.
stations = meteogalicia.get_stations(
    province="A Coruña",
    concello="Santiago de Compostela",
)

get_concellos() returns dictionaries containing idConcello, concello and provincia. Municipal identifiers are maintained as a static catalog because they are effectively stable and are used by forecast and warning services.

get_stations() reads MeteoGalicia's current station catalog and returns the original station dictionaries, optionally filtered by province and concello. Station identifiers (idEstacion) are separate from municipal identifiers (idConcello); callers should not interchange them.

Station methods:

meteogalicia.get_observation_dailydata_by_station("10144")
meteogalicia.get_observation_last10mindata_by_station("10144")

Parameter station id's and the live station catalog are available at https://servizos.meteogalicia.gal/mgrss/observacion/listaEstacionsMeteo.action?request_locale=gl

Tides methods:

meteogalicia.get_forecast_tide("3")

id availables at: https://www.meteogalicia.gal/datosred/infoweb/meteo/docs/rss/RSS_Mareas_gl.pdf

Errors:

• Methods return None when no data is available or the request fails.
