Stargazers will be over the moon.

This year’s first full supermoon will occur over the Fourth of July weekend — on Sunday, July 2, and Monday, July 3 — a bright and bold backdrop for holiday fireworks.

Also known as the Buck Moon, it will reach peak illumination at 7:39 a.m. Eastern Time on Monday, according to the Farmer’s Almanac.

“Traditionally, the full moon in July is called the Buck Moon because a buck’s antlers are in full growth mode at this time,” the almanac says. “This full moon was also known as the Thunder Moon because thunderstorms are so frequent during this month.”

In NYC, the moon will look 99% full when it begins to rise at 8:21 p.m. Sunday, per TimeAndDate.com. The full supermoon will rise at 9:22 p.m. Monday and set at 6:21 a.m. Tuesday.

The almanac recommends looking towards the southeast after sunset to watch the supermoon rise into the sky.

Fox Forecast Center meteorologist Brian Mastro told The Post there is a chance for periods of rain, including thunderstorms, Sunday in NYC.

There is also a chance of “pop-up summertime thunderstorms” on Monday.

This Buck Moon is one of four consecutive full supermoons this year — the others will be viewable on Aug. 1, Aug. 30-31, and Sept. 28-29.

Full moons happen every 29.5 days. They become supermoons when they coincide with perigee, the point in its orbit at which the moon is closest to Earth.

According to NASA, astrologer Richard Nolle coined the term “supermoon” in 1979.

A supermoon appears slightly brighter and larger than a regular full moon.

In fact, the impressive lunar phenomenon could result in a 30% brightness and 14% size increase, according to Space.com.

But the outlet noted that these differences “aren’t noticeable with the unaided eye unless one pays a lot of attention to the moon nightly.”
