How long does golden hour last in Nuuk?
Around 93 to 182 minutes each evening. It's shortest in March and September, about 93 minutes, and longest in July, about 182 minutes. In June there's no ordinary evening window: the sun stays high through the night. In January and December the sun stays low all day, so the gold merges into one long window or doesn't come at all. The farther from the equator, the longer it lasts, because the sun crosses the horizon at a shallower angle.
