Data sources and how we calculate

  • Point forecasts — cards, summit pages, route forecastData: MET Norway Locationforecast 2.0 (Norwegian Meteorological Institute). For the Carpathians it is based on the global HRES model of the European Centre for Medium-Range Weather Forecasts (ECMWF): ≈ 9 km grid, 10-day forecast, updated 4 times a day. We request the 0.1° cell around the place and keep the answer up to 3 hours so as not to overload the service. Licence: CC BY 4.0 and NLOD 2.0.
  • Our own calculations — estimates, not model outputTemperature is shifted to the real altitude of the place: −0.62 °C per 100 m. The model smooths the mountains, so wind on an open ridge at 1000–2000 m is multiplied by 1–1.5; gusts, when the model has none, are ≈ 1.5 × the wind (marked «≈»). The freezing level on the cards is computed from the temperature at height (−6.5 °C per km). The hiking verdict weighs the start, the highest point and the finish of the route, walking time from length and ascent, and daylight; it accounts for thunderstorms, wind, rain, snow and ice, frost and wind chill, heat and fog. For towns it is a city walk, not a hike.
  • ElevationsSummit and place heights come from our checked data and the Copernicus DEM GLO-30 elevation model (≈ 30 m; © DLR, Airbus, EU Copernicus programme and ESA). Where a place has no height, the model terrain height is used.
  • Sunrise and sunsetAn astronomical calculation for the place coordinates (PHP date_sun_info) in local time. Mountains on the horizon are not taken into account: in a deep valley the sun rises later.
  • Forecast map: precipitation, wind, freezing levelThe ICON-EU model of the German Weather Service (DWD): ≈ 7 km grid, runs at 00 and 12 UTC, forecast to +120 hours; we refresh the map twice a day. Precipitation — rate over the interval and type (snow share); wind — at 800 hPa (≈ 2000 m, ridge height); freezing level — height of 0 °C. Licence CC BY 4.0, source: Deutscher Wetterdienst.
  • Official warningsUkraine — Ukrainian Hydrometeorological Center, Poland — IMGW-PIB, Slovakia — SHMÚ (open CAP data, CC BY 4.0). We check every 30 minutes and show them as published: the source is official, we only display it. The Romanian service ANM publishes no open feed, so for Romania there is only a link to the ANM warnings. Avalanche bulletins and mountain rescue are in the «Official services» block.
  • Times and «updated at …»All times are the local time of the country: Ukraine and Romania UTC+2 (+3 in summer), Poland and Slovakia UTC+1 (+2 in summer). «Updated at …» is when we last received the data; «model run of …» is the start time of the model run the forecast comes from.
  • Limitations and safetyA forecast is a guide, not a guarantee: mountain weather changes fast, and valleys and ridges have their own microclimate. Check the official warnings before you go and tell someone your route. In an emergency: Ukraine 101 or 112; Poland 985 or 601 100 300; Slovakia 18 300; Romania 0725 826 668 (Salvamont) or 112.
