How to Describe the Weather in German: Summer Phrases

Introduction: Why Germans Love Talking About the Weather

There is a common stereotype that only British people are obsessed with the weather. But spend just a few weeks in Germany during the warmer months, and you will quickly realize that weather talk is the ultimate social currency here too. Whether you are striking up a conversation with a neighbor in the hallway, chatting with a colleague by the coffee machine, or ordering a cold drink at a Munich Biergarten, knowing how to talk about the weather in German is an essential skill.

Summer in Germany can be beautifully diverse. It ranges from mild, breezy days perfect for hiking in the Black Forest, to scorching, humid heatwaves where everyone flees to the nearest lake (Badesee). Being able to accurately describe these conditions not only helps you navigate daily life but also integrates you deeper into German social culture. In this comprehensive guide, we will cover everything from basic grammatical structures to colorful slang expressions that will make you sound like a native speaker.

1. The Golden Rules of German Weather Grammar

Before we dive into specific summer vocabulary, let's look at how weather sentences are structured in German. Fortunately, it is relatively straightforward, but there are a few key grammatical patterns you need to master.

Using the Dummy Subject "Es"

Just like in English, German uses a dummy pronoun to describe atmospheric conditions. In English, we say "It is hot" or "It is raining." In German, this pronoun is es (it).

• Es ist warm. (It is warm.)
• Es ist heiß. (It is hot.)
• Es ist windig. (It is windy.)

Verbs vs. Adjectives

Some weather phenomena are expressed using verbs directly, without needing the helping verb sein (to be). For example:

• Es regnet. (It is raining. / It rains.)
• Es donnert. (It is thundering.)
• Die Sonne scheint. (The sun is shining.)

Pay close attention to this distinction. While English speakers often say "It is sunny," Germans are just as likely to say "Die Sonne scheint" (The sun shines) as they are to say "Es ist sonnig" (It is sunny).

2. Essential Vocabulary for Sunny and Warm Days

When the clouds clear and the German summer finally arrives, you will want to have these essential nouns and adjectives ready. German is famous for its descriptive vocabulary, and summer weather is no exception.

Key Adjectives

• warm (warm) — Used for pleasant, comfortable temperatures.
• heiß (hot) — Used when the temperature starts to get uncomfortably high.
• sonnig (sunny) — Perfect for those cloudless days.
• schwül (humid/muggy) — That heavy, sticky air that often precedes a summer storm.
• trocken (dry) — When there is low humidity.
• wolkenlos (cloudless) — Literally "cloud-less."

Key Nouns (and How to Combine Them)

German speakers love combining nouns to create highly specific terms. For instance, you can combine die Sommer (summer) and die Hitze (heat) to talk about the intense summer heat. To understand how these words fit together, you can read our guide on German compound nouns to master building long German words easily.

Here are some of the most common nouns you will hear during a German summer:

• der Sonnenschein (sunshine)
• die Hitzewelle (heatwave)
• der Sonnenbrand (sunburn)
• die Sonnencreme (sunscreen)
• die Sonnenbrille (sunglasses)
• der Schatten (shade) — E.g., "Lass uns im Schatten sitzen." (Let's sit in the shade.)

3. How to Talk About Temperatures in German

In Germany, as in the rest of Europe, temperatures are measured in degrees Celsius (°C). If you want to discuss the forecast or complain about how hot your top-floor apartment (Dachgeschosswohnung) is, you will need to know how to state temperatures.

To state the temperature, use the phrase: "Es sind... Grad." (It is... degrees.)

• Es sind heute 25 Grad. (It is 25 degrees today.)
• Die Temperaturen steigen auf 30 Grad. (Temperatures are rising to 30 degrees.)
• Morgen wird es über 35 Grad heiß! (Tomorrow it will be over 35 degrees hot!)

4. When Summer Gets Dramatic: Thunderstorms and Rain

Summer in Central Europe is not always sunshine and ice cream. Heatwaves are frequently broken up by dramatic, sudden thunderstorms known as Sommergewitter. These storms can bring rapid drops in temperature and heavy downpours. According to the official German Meteorological Service, the Deutscher Wetterdienst (DWD), these sudden weather shifts are a standard feature of the region's climate.

Here is how to describe these dramatic atmospheric shifts:

• das Gewitter (thunderstorm) — E.g., "Ein Gewitter zieht auf." (A thunderstorm is brewing/approaching.)
• der Blitz (lightning) and der Donner (thunder)
• es gießt or es regnet in Strömen (it is pouring rain)
• die Abkühlung (the cooling down / relief from the heat) — This is a highly positive word in summer. After days of heavy, humid heat, a thunderstorm brings the much-needed Abkühlung.
• es hagelt (it is hailing)

5. Idiomatic Expressions and Slang for Hot Summer Days

If you want to move beyond textbook German and sound like a true local, you need to use colloquial expressions. Germans have some wonderfully colorful (and sometimes dramatic) ways to describe being hot.

"Es ist affenheiß!"

Literally translating to "it is monkey-hot," this is a very common, informal way to say that it is extremely hot. You might also hear "eine Affenhitze" (a monkey-heat).

"Ich schwitze wie ein Schwein."

Just like the English phrase "I am sweating like a pig," this is a highly colloquial, slightly vulgar, but incredibly common way to complain about the heat. Use this with friends, but maybe avoid saying it to your German boss!

"Die Sonne brennt."

This translates to "the sun is burning" or "the sun is scorching." It is used on those intense mid-day afternoons when there isn't a cloud in the sky and the sun feels physically heavy on your skin.

"Kaiserwetter"

Literally "Emperor's weather," this term refers to a perfectly beautiful day with bright sunshine, crisp air, and a cloudless blue sky. It originates from the Austrian Emperor Franz Joseph, who was said to always have beautiful weather on his birthday celebrations.

6. Planning Your Summer Activities: Grammar Tips

Talking about the weather is usually a gateway to making plans. If the weather is nice, you might want to go to a lake, fire up the grill (grillen), or visit a beer garden. However, expressing these plans requires a bit of grammatical precision, particularly when using conditional clauses.

When you want to say "When the weather is nice, we go to the lake," you have to choose the right conjunction. In German, this is usually wenn (if/when). If you are talking about past summers or setting up conditional sentences for your summer plans, make sure you understand the rules by reading our article on Als vs. Wenn in German past tenses.

Here are some practical examples of how to propose summer activities based on the weather:

• Wenn es morgen sonnig ist, gehen wir an den See. (If it is sunny tomorrow, we are going to the lake.)
• Es ist zu heiß, um drinnen zu bleiben. Lass uns ein Eis essen gehen! (It is too hot to stay inside. Let's go get an ice cream!)
• Hoffentlich bleibt das Wetter am Wochenende schön. (Hopefully, the weather stays nice over the weekend.)

7. Cultural Insights: German Summer Survival and "Lüften"

To truly understand German weather talk, you have to understand German weather culture. If you look at the general Climate of Germany, you will notice that summers are generally temperate but are increasingly seeing extreme heat spikes due to climate change. Despite this, air conditioning (Klimaanlage) is incredibly rare in German residential buildings.

Because of this lack of AC, Germans have developed a highly structured, almost scientific approach to managing indoor temperatures during the summer. This centers around the sacred ritual of Stoßlüften (shock-ventilation).

In the summer, the rule is simple: open all windows wide early in the morning (between 5:00 AM and 7:00 AM) to let the cool air in. As soon as the sun starts to rise and the temperature climbs, you must shut all windows completely and roll down the external blinds (Rollläden). If you open a window during the heat of the day, prepare to receive a stern lecture from your German roommates or neighbors about letting the "warm air" in!
