When Does the Sun Set in Baltimore?

Sunset in Baltimore occurs between 5:17 p.m. in early December and 8:30 p.m. in mid-June, shifting by roughly 3 minutes per day. The exact time depends on the date, your specific location within the city, and atmospheric conditions. For today's precise sunset, check the National Weather Service Baltimore/Washington office website or use the U.S. Naval Observatory's sunrise/sunset calculator, which accounts for your exact coordinates.

How Sunset Times Shift Across the Year

Baltimore's sunset window spans nearly 3 hours between winter solstice and summer solstice. In late December, darkness arrives just after 5 p.m. By late January, sunset moves to around 5:30 p.m. Throughout spring, the shift accelerates; by May, the sun lingers until 8 p.m. The longest day (around June 20) brings sunset near 8:30 p.m., after which the cycle reverses. This variation reflects Baltimore's latitude at approximately 39.3 degrees north, roughly the same as Denver and the Pennsylvania-Ohio border.

Understanding this pattern matters if you plan outdoor activities, photography, or evening commutes. A concert venue booking a sunset performance in February cannot use the same showtime in July without losing daylight atmosphere. Similarly, joggers and cyclists who rely on natural light need to adjust their schedules by 20 to 25 minutes monthly.

Finding Exact Sunset Times for Your Plans

The National Weather Service Baltimore/Washington operates a forecast office in Sterling, Virginia, and provides Baltimore-specific data. Their website includes a sunrise/sunset calendar updated daily. For maximum precision, the U.S. Naval Observatory (part of the Department of the Navy) calculates sunset times down to the minute based on your latitude and longitude. This matters if you're positioning for photography at a specific location like the Inner Harbor or Federal Hill Park; the view from Canton differs slightly from Federal Hill because of the elevation and westward direction.

Smartphone weather apps typically pull data from the Naval Observatory or similar government sources, so checking multiple apps should yield identical times. If times differ by more than a minute, the app may be using your phone's broad location estimate rather than your precise coordinates.

Why Sunset Times Don't Follow a Simple Pattern

Many people assume sunset occurs 15 minutes later each week between solstices, but the actual shift is uneven. The rate of change peaks in late March and late September (around 2.5 to 3 minutes per day) and slows in January and July (around 1 minute per day). This happens because Earth's tilt and elliptical orbit combine to create an uneven pace. Additionally, atmospheric refraction (bending of light through the atmosphere) causes the sun to appear above the horizon for roughly 2 to 3 minutes longer than it would in a vacuum, which is why sunset seems to happen slightly later than pure geometry would predict.

Twilight extends the usable daylight further. Civil twilight, when the sun is less than 6 degrees below the horizon, lasts roughly 20 to 30 minutes after sunset in Baltimore during spring and fall, and up to 45 minutes during early summer. Nautical twilight and astronomical twilight extend the dimming further, relevant mainly for navigators and astronomers.

Planning Around Sunset for Work and Recreation

If your schedule depends on daylight, build in a 15-minute buffer. Morning joggers and evening dog walkers who start at the same absolute time will lose visible light by late summer. Event planners booking outdoor venues in early winter should not expect usable natural light after 5:30 p.m., while a June event can accommodate activities until after 8 p.m.

Photography during the "golden hour," the 20 to 40 minutes before sunset, requires different scheduling depending on season. Winter golden hour at Federal Hill Park or Canton Waterfront Park occurs around 5 p.m.; in summer, it begins around 8 p.m. This affects not only the timing of shoots but also the direction of light across the harbor and cityscape.

Commuters should account for the seasonal swing in evening light. In December, rush hour (4 to 6 p.m.) occurs almost entirely in twilight or darkness. By June, the afternoon commute remains fully daylit, and rush hour traffic disperses before golden hour begins.

Related Questions

Does daylight saving time change sunset times in Baltimore? Yes. On the second Sunday in March, clocks spring forward one hour, making sunset appear one hour later on the clock; on the first Sunday in November, clocks fall back, making sunset appear one hour earlier. The actual time the sun reaches the horizon does not change, only the clock reading.

How does Baltimore's sunset compare to other East Coast cities? Boston sees sunset roughly 15 minutes earlier than Baltimore; Miami sees it roughly 30 minutes later. This is because sunset times follow lines of longitude more closely than latitude, and Baltimore lies west of Boston and east of cities in the Central time zone.

Can I watch sunset from the Inner Harbor? Yes, though the harbor faces northwest, so the sun sets inland rather than over water, unlike harbors facing west. Canton Waterfront Park and Federal Hill Park both offer clear westward views of the sunset.
