Worm Moon: What It Is and When to Spot It

Ever heard the term “Worm Moon” and wondered what’s behind it? It’s just the nickname for the full moon that shines in March (or early April in the northern hemisphere). The name comes from Native American and colonial farmers who noticed that earthworms started to appear as the ground warmed, signaling the start of spring. Knowing this can make your stargazing feel a bit more connected to history.

Origins and Meaning of the Worm Moon

The Worm Moon is part of a series of monthly moon names that helped people keep track of the seasons before calendars were common. In many traditions it’s also called the “Sap Moon” because sap begins to run in maple trees. While the name sounds quirky, it’s a useful reminder that the moon’s cycle lines up with natural changes on Earth. If you’re curious, the old naming system also includes the “Harvest Moon” in September and the “Hunter’s Moon” in October.

2025 Worm Moon Dates and Viewing Tips

In 2025 the Worm Moon reaches full on March 25th (UTC). That night the moon will be high in the sky around midnight for most of the UK and US, making it a prime time to pull out a blanket and look up. To catch the best view, find a spot away from street lights, let your eyes adjust for about ten minutes, and keep an eye on the horizon for a clear line of sight. If you have a smartphone, many free apps can tell you exactly when the moon rises and sets in your location.Want better photos? Use a tripod and set your camera to a low ISO (100‑200) with a longer exposure (around 1‑2 seconds). A lens with a focal length of 200‑300mm works well for close‑up shots, while a wide‑angle lens captures the moon against the landscape. Remember to focus manually on infinity to keep the moon sharp.

Beyond the basics, the Worm Moon can be a fun excuse to learn a bit about lunar phases. The moon’s cycle repeats every 29.5 days, so the next full moon after the Worm Moon will be the “Pink Moon” in April. Watching each phase can help you track tides, plan garden planting, or just enjoy a simple nightly ritual.

So, mark your calendar for March 25th, grab a warm drink, and step outside. Whether you’re a casual sky‑watcher or an avid photographer, the Worm Moon offers a clear, bright view that’s easy to catch. And who knows—you might spot a few early worms surfacing after the frost, giving a literal meaning to the name!
