Measured tools (7)

search
Search MeteoSwiss website content in multiple languages (DE, FR, IT, EN). Returns relevant pages with URLs that can be passed to the fetch tool. Always returns up to 10 results per page — the upstream API has a fixed page size that cannot be changed. Note: pagination may return duplicate results across pages (upstream API limitation).
Parameters:
- query (required) — string — The search query string
- page — integer — Page number for pagination (1-based). The upstream API always returns 10 results per page; page size is not configurable.
- sort — string — Sort order for results. Note: date-asc severely degrades relevance — results are dominated by page age rather than query match.
- language — string — The language for search results
- contentType — string — Filter by content type. Defaults to "content" to exclude application pages. Use "publication" for official reports.

fetch
Fetch full content from a MeteoSwiss webpage and convert to markdown or plain text. Use the search tool first to discover valid page URLs, then pass the full URL as the id parameter.
Parameters:
- id (required) — string — Identifier of a MeteoSwiss page to fetch. For this server the id is a full URL returned by the search tool. Example: https://www.meteoschweiz.admin.ch/klima/klimawandel/steigende-temperaturen.html
- format — string — The output format for the content
- includeMetadata — boolean — Whether to include metadata in the response

meteoswissLocalForecast
Get a multi-day weather forecast for any Swiss location. Returns daily summaries (temperature, precipitation, sunshine, wind, weather icon) plus a hierarchical hourly breakdown of every series. This uses official MeteoSwiss Open Data — the same forecasts powering the MeteoSwiss app and website. Accepts: - Postal codes: "8001" (Zurich), "3000" (Bern), "1200" (Geneva) - Station abbreviations: "SMA" (Zurich Fluntern), "BER" (Bern) - Place names: "Zurich", "Basel", "Lugano" Coverage: ~6000 Swiss locations (all postal codes + weather stations + mountain points). Forecast horizon: up to 9 days. Updated hourly. Each day's summary fields: temperature_min_c, temperature_max_c, precipitation_total_mm, sunshine_total_minutes, wind_avg_kmh, wind_gust_max_kmh, weather, weather_icon_url. Each day also includes "hourly": one array of per-hour objects covering every series together — { time, temperature_c, precip_mm, sunshine_minutes, wind_kmh, wind_gust_kmh } — useful for judging *when* rain, sun, or wind is expected, not just the daily summary: - Each entry's "time" is already local wall-clock time for the location (Europe/Zurich), with the UTC offset included, e.g. "2026-07-09T14:00:00+02:00". It is NOT UTC — do not convert it. - A dry/calm/sunless hour is reported as its measured value (often 0), not omitted. A fully dry day is still a full array of zero-precipitation hours, not an empty array. - Each field is independently null if just THAT series has no reading for a given hour — the other fields for that same hour are still populated. An hour is omitted entirely only when every series is missing for it. - "hourly" itself is null when no hourly breakdown exists for this location at all (a total data gap); [] only when this location supports hourly data but none was available for that specific day. - For weather stations, temperature_min_c/temperature_max_c/precipitation_total_mm are MeteoSwiss's own official daily aggregates — a different, separately-curated product from the hourly series shown alongside them. They can legitimately NOT match summing/ averaging the hourly entries for that day; this is expected, not a data error. sunshine_total_minutes/wind_avg_kmh/wind_gust_max_kmh have no official daily product for stations and are always derived from the hourly series. For postal codes/mountain points, every summary field is derived from the same hourly series shown alongside it, so it always matches summing/averaging that series exactly.
Parameters:
- location (required) — string — Swiss location: postal code (e.g., "8001"), station abbreviation (e.g., "SMA"), or place name (e.g., "Zurich")
- days — integer — Number of forecast days (1-9, default 5)

meteoswissCurrentWeather
Get real-time weather measurements from ~300 Swiss automatic weather stations (~160 full weather + ~140 precipitation-only). Returns temperature, precipitation, wind, humidity, pressure, sunshine, and more. Data updates every 10 minutes. Precipitation-only stations return only rainfall data. For 8 stations (Zurich, Basel, Chur, Sion, Altdorf, Säntis, Jungfraujoch, Grand St-Bernard), also includes daily visual observations: cloud cover, fog, rain, snowfall, hail, and snow coverage. Accepts station names ("Zurich"), abbreviations ("SMA"), addresses ("Bahnhofplatz 1 Bern"), or WGS84 coordinates. Automatically finds the nearest station.
Parameters:
- station — string — Swiss weather station or location: name (e.g., "Zurich"), abbreviation (e.g., "SMA"), or address (e.g., "Bahnhofplatz 1 Bern"). Provide either this or `coordinates`; if both are given, `coordinates` takes precedence.
- coordinates — object — WGS84 coordinates (alternative to station name)

meteoswissStations
List and search MeteoSwiss measurement stations. Filter by name, canton, or browse the full network of ~300 stations (~160 full weather + ~140 precipitation-only) across Switzerland.
Parameters:
- limit — integer — Maximum number of results (1-200, default 20)
- canton — string — Filter by canton abbreviation (e.g., "ZH", "BE", "GR")
- search — string — Search by station name or abbreviation
Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
meteoswissPollenData
Get current pollen concentration data from MeteoSwiss monitoring stations (~15 stations across Switzerland). Shows pollen levels for 7 measured species (alder, birch, hazel, beech, ash, oak, grasses) — each is always included, with a "no-current-data" status when out of season. Ambrosia (ragweed) is a MeteoSwiss forecast-only category and is not part of this OGD measurement network, so it is not included. Useful for allergy sufferers.
Parameters:
- station — string — Pollen monitoring station name or abbreviation. Omit for an overview of all stations.

meteoswissClimateData
Get homogeneous climate measurement series from Switzerland's National Basic Climatic Network (NBCN). Returns temperature, precipitation, sunshine, radiation, wind, pressure, and climate indicators (frost days, summer days, heat days) going back decades. 29 climate stations + 46 precipitation stations with daily, monthly, and yearly resolution. Use cases: "What are typical January temperatures in Zurich?", "How has precipitation changed in Basel over 50 years?", "How many heat days did Lugano have last year?" Accepts station names ("Zurich", "Basel"), abbreviations ("SMA", "BAS"), or WGS84 coordinates.
Parameters:
- limit — integer — Maximum number of data rows to return (default 30)
- station — string — Climate station name or abbreviation (e.g., "Zurich", "BAS", "Davos"). Part of the National Basic Climatic Network (29 climate + 46 precipitation stations). Provide either this or `coordinates`; if both are given, `coordinates` takes precedence.
- end_date — string — End date filter (YYYY-MM-DD). Only rows on or before this date are returned.
- resolution — string — Data resolution: daily (temp min/max/mean), monthly (full climate summary), yearly (annual summary)
- start_date — string — Start date filter (YYYY-MM-DD). Only rows on or after this date are returned.
- coordinates — object — WGS84 coordinates (alternative to station name)
