I dont think the summer solstice matches up with the longest day of the year (because of refraction), just like the winter solstice doesnt match up for the shortest day of the year, and the days and nights arent of equal length on the equinox either.  I do believe that the sun does achieve its highest angle at solar noon on the summer solstice though-- and that is its true significance.  Correspondingly, the sun has its lowest angle at solar noon on the winter solstice.

You'll find that the time of sunset stays very similar from now to about the first week of July and may be a minute or two later around June 24-27, but the time of sunrise will start to get later after tomorrow.

I remember being near the Yukon-NWT border on July 8 to 11 of 1974 and the nights at that latitude (about 63N) were just brief intervals of twilight, the sun "sets" in the NNW then rises a few hours later in the NNE. In between it gets dark enough to see the brighter planets and stars but not all the other stars. There is also a glow on the northern horizon like a sunset glow. Very different from what we're used to down south.

Considering the averages are 41/32, that's not really cold for them.

I definitely wanna see the midnight sun one day.

I'll probably be happy for at least a couple of weeks. This mid 90s thing down here is getting old.

Great post! We have 15 hour and 39 minutes of light here in Ottawa today, at least at the airport. I'm slightly north of the airport, so it's probably more like 15 hours and 40 minutes at my place.

In terms of latitude, I'd love to live between 50 and 60 degrees north. Cities like Edmonton, Dublin, Edinburgh, Copenhagan and Moscow would be ideal for me in that regard. I find our summer daylight hours to be too short, even at 45.3 north. While I'd love to see the midnight sun someday, I think a place like Barrow or Fairbanks might be too extreme, even for me.

I was trying to find the most southerly city/community in the world, using Wunderground and it looks like it's either Puerto Williams or Ushuaia, Argentina. I don't know about anybody else here, but I really like the Wunderground site as it's the only one that shows you the sunset time for a location, as well as the times of civil, nautical and astronomical twilight.

It's interesting how the daylight hours differ greatly between 50 and 60 north as opposed to between 30 and 40 north.

The summer and winter soltices are the days with the longest (and shortest) amount of daylight hours. What does not match up is latest sunset and earliest sunrise time (for summer), and this is due to the equation of time.

See http://imagine.gsfc....rs/980116c.html

Also, as a practical matter, the total daylight time differential between the solstice days and neighboring days is less than a minute.

I think this is mainly because we record sunrise/sunset at the time the first/last edge of the solar disc appears above a level horizon, thus the sun's diameter (at Earth-rotation speed) gets "double-counted" in day length.

I've often wondered: why is it that after the winter solstice, the time of sunset begins to get later almost straight away (actually a few days before the solstice) while after the summer solstice, it's the sunrise times that immediately begin to change?

I am almost positive that it's Ushuia, they claim that at least. There's a ski resort near there that claim to be the southernmost.

While in the USAF I spent a year at King Salmon, Alaska (58.4N) and though there was a short period of darkness (in the wee hours after midnight), there was an awfully long period of twilight.

For window blinds in our two-man rooms, we had vertically sliding sheets of steel, painted black.

We also had to wear mosquito nets when going outdoors during early summer. (King Salmon is in the Tundra, 12 miles inland from the mouth of Bristol Bay on the Naknek River.) As summer progressed, the mosquitoes lightened up.

58.4N is far from the Arctic but still profoundly different than the Mid-Atlantic.
