Istanbul in February

April through May and September through October are Istanbul's sweet spots. Spring brings blooming tulips to Gülhane Park and comfortable walking weather. You'll see why Ottomans were obsessed with tulips. Fall delivers crisp air and fewer crowds at major sights. Summer gets brutal—35°C heat, packed tourist sites, and hotel prices that'll make you wince. But the rooftop bar scene peaks, and you can swim at nearby Princes' Islands beaches. Winter surprises visitors. Snow occasionally blankets the Blue Mosque's domes, creating postcard moments. Indoor attractions like the Basilica Cistern feel more atmospheric. Hotel rates drop 40%, and you'll have Topkapi Palace nearly to yourself. The downside? Days end at 5 PM, and that Bosphorus ferry ride gets chilly. Ramadan timing varies yearly but affects restaurant hours and cultural sites. Many locals fast during daylight, so street food vendors close until sunset. Plan accordingly.
