\"\"Durchschnittsthemen zu Beginn des Jahres 2026: Temperaturen 2025, Durchschnittsbilder.<\/p>\n

MeteoSchweiz-Blog am 19. Dezember 2025<\/a>: 2025 ist eines der w\u00e4rmsten Jahre seit Messbeginn, auch wenn die Jahresmitteltemperatur nicht ganz an die der drei Vorjahre 2022-2024 herankommt.<\/em> Mitte Januar 2026 wird der definitive Bericht zur Einordnung des Wetters 2025 verf\u00fcgbar sein.  <\/p>\n

F\u00fcr diverse Messstationen wurden am 2. Januar 2026 die Daten zu den Jahresmitteltemperaturen aktualisiert. Damit kann zum Beispiel f\u00fcr Z\u00fcrich Fluntern ein Temperaturstreifen f\u00fcr die verf\u00fcgbaren Messdaten 1864 bis 2025 berechnet werden:<\/p>\n

\"\"In Z\u00fcrich Fluntern war das Jahr 2025 im Vergleich mit anderen Gebieten immer noch recht war (im roten Bereich). Das Jahr 2025 ist in Z\u00fcrich das sechstw\u00e4rmste Jahr seit 1864.<\/p>\n

Klimaschutz \u2013 in erster Linie als Menschenschutz zu verstehen \u2013 ist damit immer noch zwingend erforderlich, siehe dazu meinen Blogbeitrag aus dem Jahr 2025<\/a>.      <\/p>\n

Durchschnitt: zwei Bilder<\/h2>\n

Die JahresDURCHSCHNITTStemperatur ist eine statistische Gr\u00f6sse, die einen Hinweis auf ausgew\u00e4hlte Aspekte des Wetters mit gewissen Bez\u00fcgen zur Klimaver\u00e4nderung ergibt.<\/p>\n

Zur Illustration bietet sich mein digitales Spielzeug \u00abDurchschnittsbilder\u00bb an, siehe zum Beispiel ein Blogbeitrag<\/a> aus dem Jahre 2023. Ich verwende dazu \u00f6ffentlich zug\u00e4ngliche Archive von Webcams. <\/p>\n

Maighelsh\u00fctte SAC, Sektion Piz Terri, in der N\u00e4he des Vorderrhein-Ursprungs <\/h3>\n

Die Maighelsh\u00fctte<\/a> hat derzeit zwei Webcams<\/a>  in Betrieb: eine schon l\u00e4ngere Zeit mit Blick Richtung S\u00fcden, seit Herbst 2025 ist eine zweite Kamera installiert mit Blick Richtung Norden. Drei Bilder pro Tag, jeweils etwa 9, 12 und 15 Uhr, sind in einem im Internet verf\u00fcgbaren Archiv abgespeichert.<\/p>\n

Von der S\u00fcdblick-Kamera habe ich mit den aus dem Jahr 2025 f\u00fcr etwa 12 Uhr im Archiv verf\u00fcgbaren 357 Einzelbilder zu einem Durchschnittsbild zusammengerechnet: \"\"<\/p>\n

PS: Auch bei der Badush\u00fctte der SAC Sektion Manegg<\/a> etwas oberhalb des Tomasees ist eine Webcam installiert. Davon sind jeweils nur aktuelle Bilder verf\u00fcbar; somit ist ein Durchschnittsbild schwierig.<\/p>\n


\n

Im Jahr 2025 war ich 36 mal oben auf dem Uetliberg, in der Regel auf einer Wanderung vom und zur\u00fcck zum Z\u00fcrcher Friesenberg. Die an der Kanzel des Fernsehturms installierte Webcam<\/a> verf\u00fcgt ebenfalls \u00fcber ein Archiv, allerdings nur mit einem Bild pro Tag um 12 Uhr. Somit ergibt sich ein Durchschnittsbild von der Mittagszeit an jenen Tagen, an denen ich am Uetliberg unterwegs war. Offenbar gab es 2025 eine leichte Verschiebung der Kameraausrichtung, sichbar zum Beispiel an der Abbildung des Uetliberg-Aussichtsturms.<\/p>\n
