The rare part is that the first full moon of summer 2026 is a micromoon : it happens when the full moon lines up near the Moon’s farthest point from Earth, so it looks slightly smaller than usual. It also lands on June 29–30, 2026, and is the Strawberry Moon, the first full moon of summer in the Northern Hemisphere.

What makes it rare

  • A micromoon is less common than the more familiar supermoon because the Moon is near apogee , not perigee.
  • In 2026, the first summer full moon occurs right when this distance effect is happening, which makes the moon look a bit smaller in the sky.
  • The best viewing is around moonrise on the evening of June 29, when it may look low, large, and golden near the horizon even though its actual size does not change.

Why people notice it

  • It’s called the Strawberry Moon , but the name refers to the early summer harvest, not its color.
  • The timing is also close to the summer solstice, which adds to the seasonal buzz around it.
  • So the “rare” part is really the combination of first summer full moon + micromoon timing , not an unusual color or eclipse.

Quick scoop

The moon itself is not shrinking; it only appears a little smaller because it is farther away.

TL;DR

The first full moon of summer 2026 is rare because it is a micromoon , meaning it occurs near the Moon’s farthest point from Earth, making it appear slightly smaller than usual.
