Istanbul weather in October

We vacationed with my family in October in Istanbul. According to the weather, it is believed that this is the beginning of autumn. The air temperature at this time drops significantly, the average amount of precipitation increases. While Istanbul in general is still relatively warm and pleasant, it is much colder and wetter than the summer months and is no longer beach weather. The average temperature in Istanbul in October is 16°C, the maximum is only 19°C. The highest temperature may be 35°C, so perhaps you can still sunbathe a little, but overall this is not the best time for a beach holiday in Istanbul. When the temperature drops, the sea also cools down. The average sea temperature in October is 18 degrees. The days are also shortened, with an average of only 7 hours of sunshine each day.
