Northernmost sunset on June solstice


Three curved, dotted sun tracks across the sky from various heights above the horizon down to the horizon. Northernmost sunset happens in Northern Hemisphere summer.
The path of the sun across our sky – from about noon to sunset – on 3 different days of the year, an equinox and the summer and winter solstices. The June solstice is the Northern Hemisphere’s summer solstice. Notice the northernmost sunset on this day. Marcella Giulia Pace made these observations from Gatto Corvino village, Sicily, Italy.

Northern Hemisphere summer

For us in the Northern Hemisphere, the June solstice signals the beginning of summer. For the Southern Hemisphere, winter starts at this solstice. The solstice is a whole-Earth event. It happens at the same instant for all of us, everywhere on Earth, but our clocks differ by time zone.

This 2021 June solstice happens on Monday, June 21, at 3:32 UTC. Translate UTC to your time. In North America and U.S. time zones, that’s June 21 at 12:32 a.m. Atlantic Daylight Time. But it’s on June 20 at 11:32 p.m. EDT, 10:32 p.m. CDT and so on, all the way to and 5:32 p.m. Hawaiian-Aleutian Standard Time.

The June solstice marks the year’s northernmost sunset and sunrise. It brings the year’s longest period of daylight to the Northern Hemisphere (least daylight in the Southern Hemisphere). North of the Arctic Circle, the sun neither rises nor sets but stays above the horizon continuously, around the clock.

In the Northern Hemisphere, noontime shadows are shortest at this solstice. It’s the year’s highest sun, as seen from the Tropic of Cancer and all places north.

Southern Hemisphere winter

Earth’s orbit around the sun – and tilt on its axis – have brought us to a place in space where our world’s Northern Hemisphere has its time of greatest daylight: its longest day and shortest night. Meanwhile, the June solstice and northernmost sun brings the shortest day and longest night south of the equator.

This solstice marks the beginning of Southern Hemisphere winter.

It marks the lowest sun and longest noontime shadow for those on the southern part of Earth’s globe.

South of the Antarctic circle, the sun neither rises nor sets but stays beneath the horizon for 24 hours.

If you are standing facing east, the sun – from day to day, and week to week – moves progressively to the right (south) between these 2 solstices. Rupesh Sangoi captured separate images of the sunrise, showing the sun’s movement along the horizon between a June and December solstice. He wrote: “Did this for over a year, at sunrise.” Glorious composite, Rupesh! Thank you.

Northernmost sunset, but not latest sunset

The sun sets farthest north on the day of the solstice, bringing the longest day for the Northern Hemisphere. But this summer solstice doesn’t bring the latest sunset. And it doesn’t bring the earliest sunrise. The exact dates vary with latitude, but the sequence is always the same: earliest sunrise before the summer solstice, longest day on the summer solstice, latest sunset after the summer solstice.

For the Southern Hemisphere, where it’s winter now, the latest sunrise – and earliest sunrise – don’t come on the day of the solstice either. Again, the exact dates vary with latitude. But the sequence is always the same: earliest sunset before the winter solstice, shortest day on the winter solstice, latest sunrise after the winter solstice.

Each solstice marks a turning of the year.

Even as this northern summer begins with the solstice, throughout the world the solstice also represents a “turning” of the year.

To many cultures, the solstice can mean a limit or a culmination of something. From around the world, the sun is now setting and rising as far north as it ever does. The solstice marks when the sun reaches its northernmost point for the year.

After the June solstice, the sun will begin its subtle shift southward on the sky’s dome again. Thus even in summer’s beginning, we find the seeds of summer’s end.

At very northerly latitudes now, the sun is up all night. Here is the sun at 3 a.m. as seen near a June solstice by EarthSky Facebook friend Birgit Boden in northern Sweden.
