Swiss Weather Forecast (MeteoSwiss) – by Postal Code

Get the official weather forecast of MeteoSwiss, Switzerland's national weather service, for any Swiss postal code – as clean JSON, CSV or Excel. Daily for 9 days or hourly for up to 8 days.

This is the same local forecast that powers the MeteoSwiss app and website. MeteoSwiss blends its high-resolution ICON-CH1/CH2 ensemble models, INCA nowcasting and ECMWF and refreshes it every hour. It covers:

• 📮 every Swiss postal code (~3,200 locations),
• 📡 ~150 MeteoSwiss weather stations,
• 🏔️ mountain points such as passes, peaks and huts (e.g. Simplonpass, Gurnigelpass).

What you get:

• 🌡️ Daily min / max temperature and hourly temperature (with 10%–90% uncertainty range)
• 🌧️ Precipitation in mm – with a low / high estimate (10% and 90% quantiles) and 3-hour rain probability
• 🌤️ MeteoSwiss weather icon code + icon URL (daily and 3-hourly)
• 💨 Wind speed, direction and gusts, ☀️ sunshine minutes, global radiation, ❄️ freezing level

Search by postal code ("8001"), place ("Bern", "Lugano", "Geneva"), station ("BER") or coordinates (nearest point) – or get all Swiss postal codes in one run. No API key, no scraping, no login.

What can I use it for?

• 🏨 Tourism, ski & outdoor – resorts, mountain huts, tour operators: forecasts for the exact village or pass.
• 🛒 Retail, delivery & events – plan staff, stock and logistics by postal code.
• ☀️ Energy – hourly sunshine and radiation for PV forecasts, temperature for heating demand.
• 🏗️ Construction & agriculture – rain, frost and wind gusts for the next days.
• 🗺️ Nationwide datasets & maps – one run returns the whole country by postal code.
• 📱 Apps, dashboards & AI agents – a reliable Swiss forecast feed without signing up for a weather API; works as a tool via the Apify MCP server ("Will it rain in Zermatt on Saturday?").

Notes

• MeteoSwiss updates the forecast every hour; the tool always uses the latest complete run. Schedule it hourly or a few times a day for a fresh feed.
• Hourly data comes as one file per parameter for all of Switzerland (~30 MB each), so hourly runs take a little longer than daily ones – choose only the hourly fields you need.
• Place names use the MeteoSwiss point names (official locality names, e.g. Genève, Luzern); English names of the big cities work too.

Pricing

You pay only per row returned – no monthly fee. A 7-day daily forecast for one place is 7 rows; 24 hours hourly is 24 rows.
