SPOKANE, Wash.—Tuesday's temperatures are warming up around the Inland Northwest. Those temperatures arrive just in time for summer solstice on Tuesday night! It’s going to be another day in the 80’s with a light breeze in the afternoon.

Summer solstice is split between two days and two time zones.

While most people are celebrating the first day of summer, that is not the case for people in the Eastern Time Zone.

The summer solstice is the day of the year with the most hours of sunshine. Spokane will get almost 16 hours of daylight both June 20 and June 21.

The seasons are marked by two solstices and two equinoxes. The days are determined based on the Earth's tilt on its axis and the sun's position over the equator.

FUN FACT: The “dog days of summer" refers to the weeks between July 3rd and August 11th. To the Greeks and Romans, the “dog days” occurred around the day when the "dog star" Sirius appeared to rise just before the sun. That happens in late July. They referred to these days as the hottest time of the year. It was a period that could bring fever or even catastrophe.
