Boston lies at 42.4° N, and the further a place is from the equator the more slowly the sun sinks at sunset, so the evening golden hour here runs from 37 minutes in March to 45 minutes in December, against 27 to 30 minutes all year at the equator.
Plan a specific day
The lengths above are for a flat horizon and a clear sky. Buildings or hills toward the sunset end the direct light earlier, and standing higher makes sunset a little later. The golden hour calculator takes any date, your obstruction and your height, and adds an exposure ladder for the minutes after sunset.
Questions
How long is golden hour in Boston today?
Between 37 and 45 minutes, depending on the date. The table above gives the 15th of each month; for today’s exact start and end, see the Boston sunset page or the golden hour calculator, which works for any date.
How long is blue hour in Boston?
Under the PhotoPills definition (sun 4° to 6° below the horizon) it lasts 11 to 14 minutes. If you count the whole of civil twilight after sunset, which is what film crews call magic hour, it is 28 to 35 minutes.
When is golden hour longest in Boston?
Around December, at 45 minutes. Near the solstices the sun sets at a shallower angle, so it takes longer to sink through the last 6°. It is shortest around the equinoxes, in March at 37 minutes.
Is the morning golden hour as long as the evening one?
Nearly. On any date the sun climbs through the same angles after sunrise at almost the same rate as it sinks before sunset, so the morning golden hour is within a minute or two of the evening one.
