1) Whether you’re planning your Australian holiday around the weather, or want to travel when things are most affordable, here’s the rundown on the best times to visit Australia.
2) It’s no wonder that Istanbul is often mistaken as the capital city of Turkey. It is the largest city, and the city’s total area keeps expanding due to the population increase. It’s the city of business. It’s also the historic center of different empires, and it’s the only city in the world on two continents: Europe and Asia.
3) April, May, September and October are pleasantly warm, with temperatures of 68°F to 86°F, so are typically the best times to visit Turkey’s grand array of ancient sites.
4) In November and December it's quite chilly throughout most of the country, with the exception of the southeast (around Antalya) which remains fairly warm. 
5) In Turkey, the days are longer in summer (June to September) than in winter (December to March). With up to about 15 hours, there are the longest days in June. The longest dark nights, on the other hand, are in winter. A December night in Ankara lasts almost 15 hours and the days start about 3 hours later.
