Boston Sunrise & Sunset: A Seasonal Guide to Daylight and Twilight

Seasons of Sunlight in Boston

Boston, Massachusetts, sits at roughly 42.4° N latitude and 71.1° W longitude, experiencing dramatic swings in day length from summer to winter. The city uses Eastern Standard Time (EST, UTC-5) in winter and Eastern Daylight Time (EDT, UTC-4) in summer, which shifts clock time relative to solar noon. Because Boston is west of the 75th meridian that defines Eastern Time, solar noon occurs later than 12:00 PM standard time – typically around 11:45 AM EST or 12:45 PM EDT. This offset affects sunrise, sunset, and the timing of the golden hour, the period shortly after sunrise or before sunset when light is warm and diffused.

Below you’ll find tables for each season in 2026, showing key dates that mark the longest and shortest days, the equinoxes, and the heart of each season. We also discuss how Daylight Saving Time shifts your experience of daylight. For comparison with a major city across the Atlantic, see our article on Boston vs London time difference.

Spring 2026 (March – May)

Spring begins with the vernal equinox on March 20, when day and night are nearly equal. From there, daylight lengthens rapidly, gaining about 2–3 minutes per day by April. Sunrise moves from around 6:55 AM EST on March 1 to 5:12 AM EDT on May 31, while sunset stretches from 5:40 PM to 8:10 PM. The golden hour in spring occurs roughly between 6:30–7:30 AM and 6:30–7:30 PM EDT by late May.

Summer 2026 (June – August)

The summer solstice on June 21 brings the longest day, with sunrise around 5:07 AM EDT and sunset at 8:24 PM EDT — a day length of 15 hours 17 minutes. Civil twilight extends another 30–40 minutes after sunset, so the sky remains bright until nearly 9 PM. The golden hour in deep summer is exceptionally long, often lasting 45 minutes to an hour. By August 31, day length drops to 13 hours 12 minutes as summer winds down.

Autumn 2026 (September – November)

The autumnal equinox on September 22 gives equal day and night. Daylight then shortens rapidly, losing over 2 minutes per day. Sunrise on October 1 is at 6:35 AM EDT, but by November 30 it’s at 6:55 AM EST (after clocks fall back on November 1). Sunset shrinks from 7:05 PM EDT in late September to 4:15 PM EST in late November. The golden hour becomes more noticeable, especially around October when the sun hangs lower.

Winter 2026 (December – February)

The winter solstice on December 21 brings the shortest day: sunrise at 7:10 AM EST and sunset at 4:15 PM EST, giving only 9 hours 5 minutes of daylight. Civil twilight is short, with the sky fully dark 30–40 minutes after sunset. By February 28, day length increases to 11 hours 10 minutes. The golden hour in winter is brief but often spectacular due to the low sun angle. Boston’s time zone offset means solar noon occurs around 11:45 AM, so the afternoon golden hour starts earlier relative to clock time (e.g., 2:30–3:30 PM). Compare to London (GMT) where solar noon is closer to 12:00; see Boston vs London time difference for details.

How Boston’s Time Zone Affects Apparent Solar Time

Boston is located at 71.1°W, which is 4.1° west of the 75th meridian that serves as the standard for Eastern Time. This means that when it is 12:00 PM EST, the sun is not at its highest point; solar noon actually occurs around 11:46 AM EST. In summer (EDT), solar noon is around 12:46 PM. This offset pushes sunrise and sunset later relative to the clock than if Boston were on its own “natural” time. For example, the latest sunset in Boston occurs around June 27, not the solstice, because of this offset. The same phenomenon affects the golden hour: in winter, the best morning golden hour is about 7:00–8:00 AM EST, while in summer it’s around 5:30–6:30 AM EDT. Understanding these nuances helps photographers and early risers plan. If you need to schedule calls or meetings across time zones, check our Business Hours in Boston guide.
