If you love summer, Tuesday marks an exciting day — it’s the June solstice. But what does that actually mean? 

The summer solstice occurs when the sun is directly over the Tropic of Cancer, according to the National Weather Service. This year, that happens at 10:24 p.m. (MDT) Tuesday, June 20.

For the Northern Hemisphere, the June solstice marks the official first day of summer (even if most of us start our summer fun on Memorial Day) and the longest day of the year. On Tuesday, the sun will rise at 5:55 a.m. and won’t set until 9:04 p.m. in Ogden, according to the Weather Channel

The summer solstice is caused by Earth’s tilt on its axis and its orbit around the sun.  

At the June solstice, the Northern Hemisphere is the most inclined toward the sun, which is why we get the most daylight hours on this day, according to NASA. At the winter solstice on Dec. 21, the Northern Hemisphere will be the furthest tilted from the sun, making it the shortest day of the year. 

Unfortunately, the days are gradually going to get shorter from here on out until the winter solstice. Get outside and soak up the sun while you can Tuesday!
