High Noon. That would come at about 1pm this time of year, right (thanks to daylight savings time)? If we were about 300 miles south, we’d be right on the Tropic of Cancer, the northernmost latitude at which the sun appears directly overhead at its zenith.
At high noon, look at a vertical post in the sun on the longest day of the year. I haven’t tested the theory, but the amount of shadow on the north side of the post should be a measure of how far you are from the northern edge of the tropics. This is a picture of a north-facing 8 foot fence with a 2 inch shadow here.
We’re on the ragged edge.
