The best time to visit Saint Petersburg is during the late spring to early summer, particularly from mid-May through June. This period, known locally as the "White Nights," is famous for nearly round-the-clock daylight and mild temperatures that typically range from 10°C to 23°C (50°F to 73°F). The White Nights phenomenon occurs due to Saint Petersburg's northerly position, which barely dips below the horizon at night, resulting in a twilight that lasts all evening. Tourists will find this the perfect time to experience the city's outdoor festivals, open-air concerts, and the famous Scarlet Sails event – a celebration with fireworks, water shows, and a fleet of ships adorned with red sails.
Late spring and early summer also bring vibrant blooms and lush greenery to the city's many parks and gardens, making it an ideal time for leisurely walks and picnics. However, it's essential to note that this is the peak tourist season, and attractions may be crowded. If you are looking for a quieter visit with fewer crowds, consider coming in the early fall, particularly September, when the weather is still pleasant with cooler temperatures ranging from 8°C to 15°C (46°F to 59°F). The cultural calendar remains full, and the city's theatres return from summer breaks with new performances, making it an excellent time for cultural aficionados.
