Six key data points, one pattern: the moon is still very bright tonight, but it’s technically past full. The difference matters if you’re tracking lunar cycles for astronomy, photography, or calendar planning.

Is the Moon full tonight?

No. According to TheSkyLive, the moon tonight is in its Waning Gibbous phase with 98.4% illumination. It reached fullness about 24 hours ago, so to the naked eye it still appears almost completely round — but it has already begun to wane.

How to check if the moon is full tonight

  • Use a dedicated moon-phase tool like Timeanddate’s Dublin page — it shows the exact phase, rise/set times, and illumination percentage.
  • Check the TheSkyLive moon page for a real-time phase label and a countdown to the next new moon.
  • Remember that a full moon lasts only an instant astronomically, though it can appear full for a couple of nights (Space.com).

Current moon phase: Waning Gibbous

Waning Gibbous means the moon is between full and third quarter — more than half lit and shrinking each night. For Dublin tonight, the moon rises around 11:05 pm local time and sets around 5:44 am, according to Time-Ok. It’s still bright enough to cast shadows.

Bottom line: The moon is not full tonight — it’s Waning Gibbous at 98.4% illumination. Casual observers will see a nearly full disk, but the precise moment of fullness has passed.

The implication: anyone expecting a textbook full moon should check local astronomy sources rather than relying on visual appearance alone.

What moon is tonight in Ireland?

Across Ireland, the moon phase is identical because the moon’s phase is a global phenomenon — but local rise and set times shift slightly. For Dublin, tonight’s moon is Waning Gibbous with the same illumination as the rest of the country (Time-Ok).

Moon phase for Dublin, Ireland tonight

Dublin’s specific data from Timeanddate matches the global phase: Waning Gibbous, 98.4% lit. The moon rises about 11:05 pm and sets around 5:44 am. If you’re in Cork or Galway, the times will differ by a few minutes, but the phase is the same.

How moon phases vary by location

While the phase label (Waning Gibbous) is identical worldwide, the exact timestamp of “full moon” changes by time zone. A full moon at 9:45 am in Dublin on May 31 is still a full moon on May 30 in New York. That’s why some calendar apps might show the same event on different dates (Space.com).

Bottom line: The moon phase is the same for all of Ireland tonight — Waning Gibbous. The only variable is when the moon rises and sets in your specific location.

The catch: whether you see “Full Moon” on a calendar depends on the source’s timezone setting, not on the actual sky.

When is the next full moon?

For Dublin, the next full moon falls on May 31, 2026, according to Timeanddate. That same source lists the last full moon as also May 31, 2026 — meaning the current cycle just peaked.

Next full moon date for Ireland

After May 31, 2026, the following full moon occurs on June 30, 2026, according to Time-Ok. The July full moon will follow around July 30. These dates are consistent across most phase calendars for the northern hemisphere.

What’s confirmed and what’s unclear

Confirmed facts

  • Tonight’s moon is Waning Gibbous, not full. (TheSkyLive)
  • The next full moon for Dublin is May 31, 2026. (Timeanddate)
  • The last full moon was also May 31, 2026. (Time-Ok)
  • Illumination is 98.4%. (Time-Ok)

What’s unclear

  • Exact moonrise/set times vary by a few minutes across Ireland; use Timeanddate for precise local data.
  • Some websites (e.g., Nations Geo) may show a “Full Moon” label on June 1 due to caching or UTC-based timestamps, creating confusion. The most reliable local-time sources agree it’s Waning Gibbous.
  • Space.com lists a “Full Moon” for June 1 with 98% illumination, reflecting a UTC-based timestamp rather than local Dublin time.
  • Different sources may define the exact moment of full moon on different civil dates depending on their timezone setting.

The pattern: discrepancies arise when sites use UTC vs local time, not from actual phase differences.

What experts say about tonight’s moon

“Today’s moon is Waning Gibbous with 98.4% illumination.”

— TheSkyLive (real-time astronomy tracker)

“The next full moon for Dublin is on May 31, 2026.”

— Timeanddate (time and astronomy authority)

Both sources confirm that the full moon has just passed. The moon is still very bright, but the optical peak has already left.

The trade-off for anyone in Dublin: if you missed the full moon last night, tonight’s Waning Gibbous moon is almost as bright — you’ll still get great skywatching. But if you need a truly full disk for a ritual, calendar event, or photography, you’ll have to wait until the next full moon on June 30.

Frequently asked questions

How can I tell if the moon is full tonight?

Check a reliable moon-phase website like Timeanddate or TheSkyLive. They show the exact phase, illumination percentage, and next full-moon date. If the phase says “Waning Gibbous” or “Full,” you have your answer.

Is the moon full tonight in any country?

The moon’s phase is the same everywhere on Earth at any given moment. If it’s not full in Dublin, it’s not full in Tokyo or New York either — though time zones may cause the calendar date to differ (Space.com).

What does a Waning Gibbous moon look like?

It looks like a nearly full disk with a small dark sliver on the left side (in the northern hemisphere). It’s more than half lit but gradually shrinking each night. You can see it in the early morning hours after moonrise.

How long does a full moon last?

Astronomically, a full moon is a precise moment — only an instant. To the naked eye, the moon can appear full for up to three days (the night before and after) because the illuminated fraction changes slowly near 100% (Space.com).

Does the moon appear full for more than one night?

Yes, it often looks full to casual observers for two or three nights — the night before, the night of, and the night after the exact moment. That’s why someone might think tonight is a full moon when it’s actually Waning Gibbous (Timeanddate).

The bottom line: the moon’s phase data for Dublin is clear — Waning Gibbous tonight — but users should check local sources to avoid date confusion caused by timezone differences.
