Rare Strawberry Moon On First Day Of Summer, Plus Thunderstorms Likely Later This Week

Monday, June 20 is the first day of summer. Hot temperatures, which are expected this week, should not come as a surprise.

In addition to the heat, the days will be long. Sunset is at 8:33 p.m.on Monday. At 15 hours and 38 seconds, it's the longest day of the year.

To top it off, a rare "Strawberry Moon" will be on display in the night sky Monday. A Strawberry Moon has an amber glow and is very low, according to experts.

"The Sun gets super high so this Moon must be super-low. Even at its loftiest at 1 AM, it’s downright wimpy-low. This forces its light through thicker air, which also tends to be humid this time of year, and the combination typically makes it amber colored," according to an explanation in the Old Farmer's Almanac.

A Strawberry Moon coinciding with the first day of summer is uncommon, last occurring in 1967, according to the Washington Post. The astronomical event will be live-streamed by Slooh.com.

So that's what's on tap in the sky Monday.
