Legend

• Temperature (red line), °C
• −20−10−405102030The area under the temperature line is coloured by temperature: blue below 0 °C (deeper when colder); above 0 °C green, lightening through yellow, then orange and red above 30 °C. Dots with numbers mark each day's highest and lowest temperature.
• Dew point (blue line), °C — the temperature at which the air would become saturated. The closer it is to the temperature, the more humid the air.
• Pink bars along the top of the temperature chart: possible fog. Temperature and dew point are less than 1 °C apart, so the air is close to saturated (about 100% relative humidity), or the provider forecasts fog. Fog or low cloud is likely; on the summits this usually means being inside the cloud. Bars mark spells of 2 hours or more; the readout flags every near-saturated hour.
• Mean wind (dashed brown line), km/h
• Gusts (solid amber line), km/h. A dot and value mark the strongest gust in view.
• Arrows show where the wind is blowing to. Text names where it comes from, e.g. “from SW” with an arrow pointing NE. Below 1 km/h mean wind is shown as calm (hollow dot).
• Sunshine bars: share of each interval with sunshine (0–100%). Numbers above each day: accumulated sunshine hours. A * marks a total that covers only the shown part of that day or has missing hours.
• Freezing level (teal line), m: the height of the 0 °C line, from the Klein Matterhorn forecast and the same on every station page. The highest station's grid cell best represents the free air over the valley; lower cells read cold air pooled in the valley as a low freezing level. Shaded above the line: below 0 °C. Grey lines mark each station's elevation, the current station's darker.
• Background bands: cloud cover per layer, white = clear (0%), grey = overcast (100%). High, mid, and low layers are as defined by the provider (Open-Meteo: low up to 3 km, mid 3–8 km, high above 8 km).
• Symbols above the temperature line show the provider's weather at that time. Precipitation types: slanted drops = rain, dots = drizzle, sun or moon behind the cloud = showers, flakes = snow, drop and flake = frozen mix, red triangles = freezing rain, bolt = thunderstorm.
• Precipitation bars in front of the clouds: amount per hour as water, read against the mm/h scale on the left, which stays the same for the whole forecast. A dot and value mark the highest rain bar in view.
• Bar colour shows the type: blue = rain, turquoise = showers, white = snow, half blue and half white = frozen mix, red = freezing rain.
• ❄︎Over each snow spell: the fresh snow it brings in total, in cm (the provider's estimate). Just the flake when the spell is too narrow for the number.
• Hatched: the provider supplied no value. “Unavailable” is never shown as zero or clear sky.
• Grey bands mark night between the provider's sunset and sunrise times.
