1. Affenhitze - scorching heat

When translated directly, Affenhitze means monkey heat, but in this instance it is actually used to describe exceptionally hot weather or scorching heat.
So if you want to comment on what a scorcher of a day it is, you should say "Heute ist eine Affenhitze".
2. Sauregurkenzeit or Sommerloch - the quiet when everyone is on holiday

Much like Affenhitze, this term also has a funny literal translation. Sauregurkenzeit means pickle time, and originates from 18th century Berlin, when pickles from the local Spree Forest would make it to shop shelves during the late summer.
The mid-summer weeks in July and August were typically when schools and offices were empty. There wasn't much going on in the city since the inhabitants went on holiday during this period, and consequently businessmen found it tricky to make money. Hence Sauregurkenzeit became synonymous with the quiet when everyone goes on holiday.
Sommerloch, (summer hole) has the same meaning, and is typically used by the media when they have difficulties filling their newspapers for lack of events when politicians flee the city.
3. Sommerfrische - summer retreat

And where do all of the city folk rush off to during the Sauregurkenzeit? To their Sommerfrischen of course.
A Sommerfrische, a slightly outdated term for summer holiday retreat, can be in the mountains, by the sea, or tucked away in the countryside. Such retreats are popular with those who can afford to escape their busy city lives and enjoy the pleasant summer temperatures in a relaxed atmosphere.
4. Hitzefrei - when schools have to shut due to hot weather

Schools in Germany can have classes running into July and August. Hence, teachers and pupils sometimes end up working in warm temperatures, though Germans do draw the line if thermometers register between 25C and 30C in the shade. At this point, staff and students are sent home, and the day is deemed Hitzefrei, or heat-free.
5. Kaltstellen - to chill something in the fridge

In theory you can use this word at any time of year, but you'll probably find yourself employing it more in summer when the baking hot weather leaves you in want of a cold beer, a chilled glass of wine or refreshing summery cocktail.
Kaltstellen means to keep something cool in the fridge, and can also be used colloquially to mean to sideline someone or throw someone out.

June 20th or 21st is the the longest day of the year, the summer solstice. Germans in the northern states of Schleswig-Holstein, Lower Saxony and Mecklenburg-Western Pomerania welcome it by enjoying a large bonfire.
The bonfire may be part of a Volksfest (fair), where sausages and beer among other items are on sale.
