Thessaloniki is Greece's 2nd largest city and is the capital of Northern Greece also known as the Macedonia region. It is a port side city. The weather in Thessaloniki borders the Mediterranean climate - summers can be hot and humid, while winters can get chilly. Snow has also been witnessed during winter, but it is not frequent. The best time to visit Thessaloniki is Mid August to Mid October when you can enjoy many festivities along with great weather.

Spring brings with it freshness in the air and is always a lovely time to take a trip. You can expect an average temperature of 15°C starting in March and getting warmer by May. The chance of rain is quite rare during these months. Beautiful flowers bloom during this period making the city quite vibrant. Tourism is slow so you can enjoy sights of interest in peace.

The Thessaloniki International Book Fair is held every year in May and is a lovely festival for all book lovers.

Summer is a high tourist season for Thessaloniki. The days are usually hot and sunny with an average temperature of 28°C. No rain is expected. Being the cultural capital of Greece, there are many festivities held here, especially during the summer months.

One of the biggest festivals of Thessaloniki is the Street Mode festival which celebrates urban culture through music, dance performances, street art and more. It is usually held during the end of August. Another popular festival is the Urban Picnic Festival, held every year during the summer. The festival is a combination of great food, great music, open-air cinema, concerts all at the iconic architectural spot of the Roman Agora.

September is still a fairly crowded season and the temperature feels like summer with an average of 25°C. However, by November, the temperature drops to 15°C and the air cools down. There are chances of rain for about 3-4 days per month.

Thessaloniki winters are not too harsh and can be quite enjoyable. Rain can be expected 8-10 days in a month during this time and occasionally it also snows. It can get quite hazy and foggy through the day which adds to the serenity of the place. The average temperature during winter is 6°C and the sun sets at around 5:30 pm, giving you ample time to do your share of sightseeing. The downside is that most of the restaurants do not have outdoor seating, because the evenings are quite chilly so you do miss out on the nightlife liveliness.
