Zangle Fall Late Afternoon

"Zangle Fall Late Afternoon", 8 x 10 In, Oil, 2011

Painted years ago looking out from my studio window. The tides and currents on Zangle Cove continuously change, in a rythym related to the gravitational forces of the moon and the sun and the seasons. In the fall and winter, the highest tides are during the day and in the spring and summer the lowest tides are during the day. This is lucky for us, because when the tide is a -4, it is a different universe. In the painting, as you can see, it is close to high tide during late afternoon, which is consistent with the fact that the highest tides during the fall/winter are during the day.

"Why are the two tides in a day different in size? One of the low waters in a day is often much lower than the other in our region. This has an interesting pattern over a year: in summer the lower low water happens in the day, but in the winter it happens at night. The reason has to do with the tilt of the Earth's axis relative to the sun - the same tilt that causes Summer and Winter. The extra tug the tides feel once a day causes the difference in the low waters."
