Dusk and twilight in Marco Island on September 23, 2026
Civil dusk in Marco Island on September 23, 2026 is at 7:44 PM — the moment the sun reaches 6° below the horizon and the sky loses its last usable natural light. That is about 23 minutes after the 7:21 PM sunset, the gap during which street lights and headlights start to take over.
Twilight then deepens in stages: civil dusk at 7:44 PM gives way to nautical dusk at 8:11 PM (sun 12° down, horizon fading) and finally astronomical dusk at 8:38 PM, after which the sky is fully dark for stargazing. The best photographic slice sits just before civil dusk — the 7:38 PM – 7:44 PM blue hour, when the sky glows an even cobalt.
How long that whole hand-off lasts depends on latitude: at 25.9°N, Marco Island sees a moderate seasonal change in day length, so twilight stretches out in autumn compared with the tropics. With the days are drawing in through September, dusk creeps a little earlier each evening. Step the date above to plan any night.
