Istanbul, Turkey Weather and Climate

Geographical location

Istanbul is the most populous city in Turkey. It is also the only city on earth that is partially located in both Europe and Asia.

The city of Istanbul has about 15 million inhabitants and has grown rapidly over the past century. It is one of the 15 largest cities in the world. However, there is no exact count of the population.

The city on both continents is so sprawling that even the locals don’t know where to go. The city continues to grow, developing mainly in the north along the canal, as well as in the south along the coast.

The location of Istanbul has always been strategically valuable, which is why the city can look back on an eventful history under different names, one of which was the old Constantinople. For the Greeks as well as the Romans – today’s Istanbul has always been the center of culture and trade.

The geopolitical transit situation becomes even clearer if one takes a closer look at a map of Europe and Asia. There is the Black Sea, which separates the Asian continent and the European continent. In the south of the Black Sea, however, there is the Bosphorus Canal, which connects the inland sea with the Mediterranean Sea, and Istanbul is on both sides of this canal. The city lies like a bridgehead and has made use of this position over the centuries.

Climate in Istanbul

Istanbul’s climate is Mediterranean, mild and humid. Typically for the region, the winters are comparatively wetter, but always quite mild. Frost and snow are the exception, but have happened again and again in recent years. Normally, the daytime temperatures in Istanbul reach around 10 degrees Celsius even in December and January. With the spring, the temperatures rise steeply.

Already in mid- April, the 20 degree mark is constantly cracked. In summer it becomes very warm in the urban area, whereby the winds (Meltem from the north and the Scirocco from the south) can influence the perceived temperatures. Similar to cold periods in winter, longer lasting heat waves are therefore also possible in summer and have occurred more frequently in the recent past in particular. Autumn in Istanbul is mild with daytime temperatures between 20 and 24 degrees and around 7 hours of sunshine.

When is the best time to visit Istanbul?

Istanbul has a lot to offer in every season, which is why it is difficult to describe an explicit time as the best travel time. Still, spring through fall is the best half of the year for most travelers. Since it can get very hot in the middle of summer, especially in the city center, we recommend the months of May and June as well as September and October as the best travel time.

Basically, the spring months of March and April are ideal for sightseeing and tours with a cultural focus, despite the slightly cooler temperatures. Only the wetter winter months in mid- November until the end of December should not be classified as the perfect travel time, as the weather can now be unpredictable and sometimes unpleasant.

Sights & attractions

The Hagia Sofia, or Sofienkirche, is a once Byzantine church, which was then Orthodox, Catholic and later adapted into a mosque. Today it is a museum. Due to its architectural uniqueness, it is considered a total work of art without a model. It stands out as the last large late-antique church that was built in the Roman Empire. It was built on a gigantic scale. The laying of the foundation stone goes back to the year 532.

Hagia Sofia has a dome with a diameter of 31 meters. It is one of the most outstanding buildings of late antiquity, which is still preserved today.

It also shows the high level of architecture and culture of the past. The palace was the seat of the sultans for many centuries and was also the administrative center of the Ottoman Empire.

The Topkapi Palace is not a single building, but a whole area of ​​buildings with designed open spaces. Overall, the palace is divided into 4 courtyards, each separated by a gate. The beginning of the palace is given as 1453. The breathtaking Cisterna Basilica is also one of the marvels of late antique architecture that you shouldn’t miss. The basilica is sometimes referred to as a sunken palace and served as a water reservoir. The cistern is 145 meters long and 65 meters wide. It was created in the 6th century AD, so it has parallels to Hagia Sofia. The capacity of this underground structure is around 80,000 liters. A mood comparable to 1001 nights.
