Munich in October: 14°C / 57°F afternoons, 6°C / 43°F nights, the last four days of Oktoberfest, then sunset soon after five from the 25th.
Dress for the city after the Wiesn. NOAA's figures for the DWD-run Nymphenburg station give Munich's October 14°C / 57°F by day and 6.1°C / 43°F at night, with 67mm of rain over about 12 days. Oktoberfest closes on Sunday 4 October; then the month shortens fast. Statistisches Amt München counts about 123 hours of sunshine against 170 in September, and on the 25th the clocks go back, pulling sunset from about ten past six to about ten past five. The bright days belong to the Föhn, a warm, dry wind off the Alps that DWD says lifts temperatures well above the seasonal norm. Pack for the Lange Nacht der Museen on the 17th and the Auer Dult the next morning: wool you open indoors, a trench you belt outside.
The Wiesn gets the first four days of October. Munich gets the other twenty-seven, and spends them in galleries, at market stalls and on the walk home after dark.

Wear it open at noon and belted after dark. A camel trench to the knee sheds a 67mm month without the weight of a wool coat, and the double-breasted front closes over a cashmere crew when the night settles at 6°C / 43°F. It is what you queue in at Odeonsplatz for the Lange Nacht shuttle, and it folds over an arm in every heated gallery after that.

Of everything worn at the Wiesn, this is what carries on past 4 October. The muenchen.de outfit guide calls the Janker jacket "suitable for cooler evenings", and a charcoal boiled-wool cardigan in that cut, with a round neck and a column of engraved buttons, covers a tent on the 1st and a Schwabing Wirtshaus on the 20th. Boiled wool shrugs off a passing shower that soaks a plain knit.

Seven hours of galleries rest on this layer. The Lange Nacht der Münchner Museen runs from 18:00 to 01:00 on 17 October across more than 100 venues, in and out of heated rooms and onto shuttle buses, and a cashmere crew keeps you warm at a 6°C / 43°F stop without overheating you indoors. Heather-oat stops the charcoal cardigan and the brown trousers reading as one dark block.

Wool flannel stays warm at 6.1°C, where cotton chinos go cold the moment the light goes, and after the 25th that happens at about ten past five. Choose a brown so dark it reads almost black under gallery lighting, then let the camel, chestnut and oxblood warm it in daylight. One pair covers the Dult on a Sunday morning and a Wirtshaus table the same night.

Plan to walk on Sunday 11 October. The Munich Marathon starts at 9am from Olympiapark and runs past the Siegestor, through Marienplatz and the Englischer Garten, so the centre belongs to runners that morning. Chestnut leather sheds a shower across about 12 wet days, elastic sides pull on in one move at the hotel door, and the plain toe still looks right at dinner.

Add it on the 25th. When the clocks go back, a 6pm walk that still had light on the 24th happens in the dark, and the temperature falls with the light toward 6°C / 43°F. A long oxblood scarf wraps twice at the open throat of a trench, and it is the only colour in a capsule of camel, charcoal, oat and brown.

Carry it to the Auer Dult. About 250 stalls of enamelware, ceramics and antiques fill Mariahilfplatz from 17 to 25 October, open 10:00 to 19:00, and zipped pockets keep a wallet shut while your hands turn over a jug. The long strap goes across the body in a crowd, and tan-brown leather sits between the chestnut boots and the camel trench.

October is drier than September, 67mm against 80, and only about 7 of its 12 wet days bring more than 2.5mm. That is compact-umbrella weather, not full-canopy weather. It folds into the shoulder bag between shuttle buses on the Lange Nacht, and the other five wet days are drizzle the trench handles on its own.
Camel trench open · heather-oat cashmere crew · dark brown wool trousers · chestnut Chelsea boots · tan leather shoulder bag. The Auer Dult on Mariahilfplatz when the stalls open at ten, coffee in the Au, the Alte Pinakothek by early afternoon.
Charcoal Trachten cardigan over the cashmere · same trousers and boots · trench belted · oxblood scarf · compact umbrella in the bag. The Lange Nacht der Museen from six on 17 October, the shuttle bus from Odeonsplatz, home after one at 6°C / 43°F.
A suggested look — camel trench coat, heather-oat cashmere crew, dark brown wool-flannel trousers, chestnut chelsea boots.
Cool, damp and shortening. NOAA NCEI's figures for the München-Nymphenburg station, which Deutscher Wetterdienst (DWD) operates, give an average October high of 14.4°C and a low of 6.1°C / 43°F, with 67mm of rain across about 12 days of measurable rain. Only about 7 of those bring more than 2.5mm, so about five are drizzle. Statistisches Amt München counts about 123 hours of sunshine, down from 170 in September. The exception is a Föhn day, when a warm, dry wind off the Alps clears the cloud and lifts the afternoon well above the norm.
A camel double-breasted trench, a charcoal Trachten-style cardigan, a heather-oat cashmere crew, very dark brown wool-flannel trousers, chestnut leather Chelsea boots, a long oxblood wool scarf, a tan leather shoulder bag with zipped pockets and a black compact umbrella. That covers 14°C / 57°F at the Auer Dult at noon and 6°C / 43°F at a shuttle stop after the Lange Nacht. Add a dirndl or Lederhosen only if you reach the Wiesn before it closes on 4 October. Leave suede at home; about 12 wet days will mark it.
Whatever you can sit in on a bench for hours. The city's outfit guide on muenchen.de is plain about it: "There is no dress code at Oktoberfest; any outfit is permitted." The 2026 festival's last four days run from Thursday 1 to Sunday 4 October, and the same guide says the Janker jacket suits cooler evenings, which in early October means the walk out of the tent toward 6°C / 43°F. For a seat, avoid Saturday 3 October: German Unity Day is marked very busy from 3pm on the official crowd barometer.
Late October for the city, early October for the festival. The first eleven days hold the last four of Oktoberfest, ending Sunday 4 October, and the Munich Marathon on Sunday 11 October, which starts at 9am at Olympiapark and passes the Siegestor, Marienplatz, the Englischer Garten and the Werksviertel. The second half has the Lange Nacht der Münchner Museen on Saturday 17 October, 18:00 to 01:00 across more than 100 venues on a €20 ticket that includes the shuttle buses, and the Kirchweihdult on Mariahilfplatz from 17 to 25 October. From the 25th, sunset comes an hour earlier.
October sits in the middle of a steep drop. DWD's figures give September 19°C / 66°F by day and 8.5°C / 47°F at night; NOAA's Nymphenburg record gives October 14.4°C and 6.1°C, and November 8.1°C / 46°F and 1.9°C / 36°F. The afternoon falls 4.6 degrees into October and another 6.3 into November. September needs a light coat for an evening at a beer-garden table, and November a loden coat against Hochnebel fog. October is the month between: a trench and a Trachten cardigan, with the Wiesn at one end of the month and the early dark at the other.
Wool, and more of it once the Wiesn is over. Lodenfrey began in 1842, when Johann Georg Frey, 21, took out a weaving licence in Munich; its water-repellent loden won a gold medal at the 1855 Paris World Exposition, and the Maffeistraße flagship, bombed in 1944, reopened in 1949. Full dirndl and Lederhosen go back in the wardrobe after 4 October, but single pieces stay out: a Janker or a loden jacket over dark trousers and a knit. Bogner, which Willy Bogner Sr. opened as a ski shop on Schommerstraße in 1932, covers the sportier end.
