Sun Position and Seasonality

During the winter seasons, the sun resides in the southern portion of the sky for the entire day. This is due to Earth's tilt. So even at noon, the sun is not 90 degrees from the horizon. The highest number I recorded was at 1:00 pm, with an angle of 39 degrees from the horizon. Between the shortened daylight hours and lack of direct sunlight, the average temperature plummets for the months of winter. Eventually Earth will reorient itself with the sun to provide the northern hemisphere with some more spring and summer sunshine to warm back up our region.
