When Does the Sun Set in Chattanooga Each Day?

Sunset in Chattanooga occurs between 5:00 p.m. and 8:45 p.m. depending on the date. Winter solstice (around December 21) brings the earliest sunset near 5:00 p.m., while summer solstice (around June 21) delays it until 8:45 p.m. The city sits at roughly 35 degrees north latitude, which determines how dramatically daylight shifts across seasons.

Why Chattanooga's Sunset Times Vary So Much

The 3 hour 45 minute swing between shortest and longest days reflects the city's position on Earth. At higher northern latitudes (like Seattle or Montreal), sunset variation exceeds 4 hours. At lower latitudes (like Miami), the difference shrinks to under 2 hours. Chattanooga's mid-latitude location produces moderate but noticeable seasonal change.

This matters for planning. A dinner reservation at 6:00 p.m. in June still has natural light. The same time in December means full darkness outside. Photographers aiming for golden hour have roughly 20 to 30 minutes of usable light after official sunset, depending on cloud cover and how far west they position themselves relative to the Tennessee River.

Finding Exact Sunset Times for Specific Dates

The National Weather Service operates a Weather Prediction Center that provides sunset data tied to your exact location. You can input your Chattanooga address (or the specific neighborhood, park, or viewpoint) and receive precise times. The agency updates these predictions seasonally as Earth's orbit evolves.

Sunset differs slightly depending on elevation and proximity to horizons. Standing on Lookout Mountain (elevation 2,126 feet) versus the Riverwalk along the lower Tennessee River (elevation roughly 650 feet) will show minor time differences, though rarely more than a few minutes. If you're planning an event at a specific landmark, the Weather Prediction Center allows location-specific queries rather than relying on city-wide averages.

Most phone weather apps (Apple Weather, Google Weather, Weather Underground) auto-detect your location and display that day's sunset time without manual lookup. These pull from the same underlying NOAA data but update hourly.

Daylight Saving Time and Sunset Times

Chattanooga observes daylight saving time (DST), which shifts clock time but not actual solar time. On the first Sunday in March, clocks spring forward one hour. Sunset times jump one hour later on the clock, though the sun still sets at the same moment in the sky. The reverse occurs on the first Sunday in November.

This creates a jarring effect in November: sunset times listed for November 4 (end of DST) show a dramatic earlier time compared to November 3, even though the sun's actual position changes by only one day's worth. The clock change, not the sun, creates the difference.

For outdoor activities, the real consideration is how much daylight remains. In mid-November, you lose roughly 2 minutes of daylight per day as you approach winter solstice. In mid-February, you gain roughly 2 minutes per day as you approach spring equinox. These small daily increments compound quickly; by late February, sunset occurs roughly 1.5 hours later than it did in late December.

Planning Around Chattanooga's Sunset

Local parks and natural areas with sunset viewing potential include Lookout Mountain's various overlooks (free to access, though some areas charge parking fees ranging from $3 to $15 depending on the lot), the Riverwalk near the Hunter Museum and Tennessee Aquarium (free), and Reflection Riding on the north slope (admission typically $5 to $10 for adults, though rates should be confirmed directly). Each faces different directions and offers distinct views.

The Hunter Museum parking area provides river views; sunset occurs to the west across the river valley. Lookout Mountain overlooks face multiple directions depending on which viewpoint you choose. Point Park at the top of the Incline Railway (the railway itself costs around $15 to $18 per ride; verify current rates on their website) positions you above most nearby terrain, extending visible sunset by 10 to 15 minutes compared to ground level.

Cloud cover reduces visibility significantly. Clear skies in Chattanooga are most common in October and November (fall often brings low humidity and stable air masses). Late spring and summer thunderstorms can block views entirely even if sunset times show no obstruction.

Related Questions

Can I predict sunset times several months in advance? Yes. The National Weather Service publishes sunset tables for any location months ahead because Earth's orbital position follows a predictable pattern. Exact times rarely shift more than 1 to 2 minutes from annual predictions unless your location is recorded at higher precision (different elevation or street address).

Does Chattanooga's river location affect when it gets dark? Not meaningfully for sunset itself, though riverfront locations can appear darker earlier if tall buildings or terrain block the western sky. Open ridges and elevated areas see the sun longer. The Riverwalk will darken first; Lookout Mountain viewpoints will retain light longest.
