Stockholm’s location just south of the 60th latitude means that the number of daylight hours is relatively small during winter – about six hours, while in June and the first half of July, the nights are relatively short, with about 18 hours of daylight. Around the Summer solstice the sun never reaches further below the horizon than 7.3 degrees This gives the sky a bright blue colour in summer, also when looking straight up towards the zenith, with few stars visible. This is not to be confused with the Midnight sun, which occurs north of the Polar circle, around 7 degrees further north.
