Munich weather is a liar. Honestly, if you check your iPhone weather app before a trip to the Bavarian capital, you’re only getting half the story. One minute you’re sipping a Radler under a chestnut tree in a beer garden, basking in 25°C heat, and the next, a wall of water is dumping on your Schnitzel.
It's unpredictable.
The weather in München Germany is defined by its proximity to the Alps. This isn't just a scenic backdrop for your Instagram photos; the mountains act as a giant atmospheric playground that dictates exactly how miserable or magnificent your day is going to be. You’ve probably heard of the "Foehn" wind, right? It’s this weird, warm, dry wind that sweeps down from the mountains. Locals blame it for everything—headaches, irritability, even a spike in crime.
When the Foehn hits, the sky turns a crystalline, impossible blue. You can see the Alps so clearly they look like a cardboard cutout. But that beauty comes with a price: a sudden, jarring jump in temperature and a dry pressure that makes some people feel like their head is in a vice.
Why the "Best Time to Visit" is Kinda Subjective
Most travel blogs tell you to visit in June or July. They aren't lying, but they aren't telling the whole truth either. July is technically the hottest month, with average highs around 24°C, but it’s also frequently the wettest.
Think about that for a second.
You pack for a summer holiday and end up spending 40% of your time under a drugstore umbrella. The rain in Munich isn't usually that depressing, grey drizzle you get in London. It’s more dramatic. You get these massive, booming afternoon thunderstorms (Gewitter) that clear the air and leave the cobblestones steaming.
The Shoulder Season Secret
If you want my honest opinion, May and September are the sweet spots.
In May, the city is literally waking up. The beer gardens open their heavy wooden gates, and the chestnuts start to bloom. Temperatures hover around a comfortable 18°C. September is even better, provided you aren't allergic to crowds. While the "weather in München Germany" during Oktoberfest is notoriously hit-or-miss—it’s actually rained during the opening parade more times than I care to count—the "Old Wives' Summer" (Altweibersommer) often brings stable, golden days that are perfect for hiking nearby Tegernsee or just lounging in the Englischer Garten.
Breaking Down the Seasons (The Real Version)
Winter (December – February)
It gets cold. Not "Arctic tundra" cold, but a damp, biting chill that gets into your bones. January is the freezer of the year, with averages sitting right around 0°C.
Snow? It’s a toss-up.
Some years, Munich looks like a snow globe for three months straight. Other years, it’s just grey slush. If the Siberian anticyclone decides to pay a visit, temperatures can plummet to -15°C. You’ll want layers. Many, many layers. But there is a massive upside: the Christmas markets (Christkindlmärkte). Drinking hot Glühwein in the freezing cold is a core Munich experience that just doesn't work if it's 10°C outside.
Spring (March – May)
March is a tease. You’ll get one day of 15°C sunshine where everyone rushes to the Isar river to grill, followed by three days of surprise snow. This is what locals call Aprilwetter—April weather—which is basically a synonym for "mood swings." By May, things stabilize. The rainfall starts to pick up, averaging about 100mm for the month, but it’s the price you pay for the city turning lush and green.
Summer (June – August)
This is "Eisbachwelle" season. If you’ve seen those surfers on the standing wave at the edge of the park, this is when they’re most active. Highs can occasionally spike into the mid-30s during a heatwave, and since air conditioning is still relatively rare in Munich apartments and older hotels, it can get sticky.
Autumn (September – November)
October is when the light changes. It gets lower and more golden. While the daytime is pleasant (around 14°C), the nights start to drop toward freezing. November is, quite frankly, the "ugly duckling" of Munich months. It’s cloudy about 64% of the time. It’s dark. It’s damp. But hey, the museums like the Alte Pinakothek are world-class, so it's a good time to stay indoors.

The Foehn: Munich’s Meteorological Ghost
You can’t talk about weather in München Germany without mentioning the Föhn.
It is a meteorological phenomenon where moist air from the south hits the Alps, loses its moisture as rain on the Austrian side, and then tumbles down into the Bavarian basin as warm, dry air. It can raise the temperature by 10 degrees in an hour.
People in Munich are obsessed with it.
If a colleague is grumpy or someone makes a mistake at work, they’ll often shrug and say, "It’s the Foehn." There’s even a term for it: Föhnkrankheit (Foehn-sickness). While scientists debate how much of this is psychosomatic, the physical effect on the atmosphere is undeniable. The visibility becomes insane. If you go to the top of the Alter Peter church tower during a Foehn event, the mountains look like you could reach out and touch them, even though they’re 50 miles away.
What You Actually Need to Pack
Forget the fashion show. Munich is a "functional clothing" kind of city. Even the fancy people at the opera usually have a sturdy coat in the cloakroom.
- The Layering Rule: Even in July, bring a light sweater or denim jacket. When the sun goes down, the proximity to the mountains means the temperature drops fast.
- The Rain Strategy: A flimsy travel umbrella will be destroyed by a Munich thunderstorm. Get something with a bit of backbone or a decent raincoat.
- Footwear: If you’re visiting in winter, forget sneakers. The salt they put on the roads to melt ice will ruin suede and leather. You need something with a rubber sole and some grip.
Real Talk: Dealing with the Rain
Munich gets more rain than Berlin. There, I said it.
The city averages about 900mm of precipitation a year. Because of this, the city is prepared. There’s an entire culture of "indoor" Munich. The city has some of the best museums in Europe (Deutsches Museum is massive enough to get lost in for three days), and the shopping passages like the Fünf Höfe are covered.
Don't let a rainy forecast ruin your trip. Most of the time, the rain is just a passing phase of the day.
Actionable Insights for Your Trip
If you are planning your visit right now, here is exactly how to handle the Munich climate like a local:

- Check the "Regenradar": Download a local weather app like WarnWetter (from the German Weather Service) or check a rain radar. The "chance of rain" percentage is useless; look at the actual radar movement to see if a cell is passing through.
- Beer Garden Etiquette: If the sky looks dark, look at the locals. If they aren't moving, the storm is far away. If they start packing their Brotzeit bags, run for cover.
- Mountain Trips: If you're heading to Neuschwanstein or Garmisch, check the weather there, not in Munich. The mountains create their own microclimates. It can be sunny in the city and a blizzard at the Zugspitze.
- Embrace the "Gemütlichkeit": If it’s pouring, find a traditional Wirtshaus (tavern). There is nothing better than watching rain lash against a window while you’re inside eating Schweinebraten and drinking a dark beer.
Basically, Munich weather is a bit of a diva. It demands your attention, changes its mind constantly, but when it decides to perform, there is nowhere more beautiful on earth. Pack for everything, expect the unexpected, and always keep an eye on those mountains.
