The summer solstice happened at 4:24 am on Sunday morning, and our friends at EarthSky explain that in addition to heralding the longest days of the year, the longest sunsets of the year happen around the summer & winter solstices:
That is, it takes more seconds for the body of the sun to sink below your western horizon around the solstices, and fewer seconds around the equinoxes. It’s true whether you live in Earth’s Northern or Southern Hemisphere … At more northerly temperate latitudes, the sunset duration is greater; and at latitudes closer to the equator, the sunset duration is less. Near the Arctic Circle (65 degrees north latitude), the duration of a solstice sunset lasts about 15 minutes. At the equator (0 degrees latitude), the solstice sun takes a little over 2 minutes and 15 seconds to set. Regardless of latitude, however, the duration of sunset is always longest at or near the solstices.
As it turns out, the sunset and sunrise are a tad longer on the December solstice than they are on the June solstice. That’s because the sun is closer to Earth in December than it is in June. Therefore, the sun’s disk looms a bit larger in our sky in December, and so it takes slightly longer to set.

I originally shared Etzel’s tasty sunrise photo back on June 22, 2020 a few days after he shared it. Here’s a couple more great shots, but for sure check them all out in his Chasing SunRise/Set gallery on Flickr.
