Strawberry Moon 2025: What it is, when to watch, and why it might look red

Skywatchers in the U.S. and UK are in for a treat as June's full moon—known as the Strawberry Moon—lights up the sky in the early hours of June 11, 2025.

Why is it called the Strawberry Moon?

The name comes from Native American traditions, where June’s full moon signaled the time to harvest wild strawberries. Despite the name, the moon doesn’t actually turn pink—though this year, it just might appear reddish.

When to see it

U.S.: The moon will reach peak illumination at 3:44 a.m. ET on June 11. However, it will look full as it rises on the evening of June 10, making that night the ideal time for viewing.


UK: Stargazers can catch the Strawberry Moon late on Tuesday night, June 10, as it appears low in the southern sky.

Why could it look red?

This year’s Strawberry Moon might live up to its name in color, thanks to its unusually low position in the sky. Because it’s sitting so close to the horizon, its light passes through a thicker layer of the Earth’s atmosphere. That scatters blue light and lets more red and orange hues through—similar to what you see during a sunset.

The reddish tint may also be intensified by haze from wildfires, adding to the spectacle.

What’s causing the moon to sit so low?

It’s all due to a rare astronomical event called a major lunar standstill, which occurs only once every 18.6 years. During this time, the moon reaches the most extreme points in its orbit—rising and setting at its northernmost and southernmost positions.

This causes June’s full moon to trace a particularly low arc across the sky, making it appear larger and more colorful to the naked eye. The last time this happened was in 2006, and we won’t see it again until 2043.

How to watch it

Look toward the eastern horizon as the moon rises after sunset on June 10.

For the best view, try to find a location away from city lights with a clear view of the horizon.

Weather permitting, parts of the UK and U.S. will enjoy excellent visibility.

Is it really pink?

No—but it might look reddish or orange. The name "Strawberry Moon" comes from seasonal tradition, not color. The reddish appearance is an optical effect caused by the moon’s low angle and atmospheric conditions.
