admin Friday, June 21 was the longest day of 2019, and the start of the summer season, for anyone living north of the equator.
Technically speaking, the summer solstice occurs when the sun is directly over the Tropic of Cancer, or 23.5 degrees’ north latitude. This will occur at exactly 11 Eastern on Friday the 21st
The exact moment for the solstice point Earth reaches in its orbit where the North Pole is angled closest to the sun calculated by Astronomers
People living on the Tropic of Cancer, 23.5 degrees north of the Equator, experiences sun pass straight overhead at noon.
Six months from now the sun will reach its southern extreme and pass overhead for people on the Tropic of Capricorn, and northerners will experience their shortest days of the year, at the winter solstice.
We all know that the Earth makes a complete revolution around the sun once every 365 days, following an orbit that is elliptical in shape. This means that the distance between the Earth and Sun, which is 93 million miles on average varies throughout the year. During the first week in January, the Earth is about 1.6 million miles closer to the Sun, referred as perihelion, whereas the aphelion is the point where Earth is 1.6 million miles farther away from the Sun. This fact may sound counter to what we know about seasons in the northern hemisphere, but actually the difference is not significant in terms of climate and is not the reason why we have seasons. In fact, Seasons are result of the Earth is tilted on its axis by 23.5 degree.
In northern OH/northwest PA, the maximum daily temperature occurs nearly 3 weeks in mid-July. Just as the warmest part of the day usually occurs several hours after noon, when the sun is highest in the sky, so too does the warmest part of the summer lags the summer solstice. This lag is due to the time required for ground and the water to heat up. Average temperatures continue to rise until the sun drops lower in the sky. Source-National Weather Service
