Check What Time to Start Watching the 2026 Geminid Meteor Shower on December 14

As of October 19, the shower is still nearly two months away.

When can you see it?

The Korea Astronomy and Space Science Institute (KASI) monthly table for December lists the Geminid peak (ZHR=150, IMO basis) at 23:00 on December 14. That is nighttime in Korea, so you can watch the peak as it happens.

NASA gives the 2026 active period as December 4 to 17 and the peak as December 13 to 14. It says the shower is visible through the night and the predawn hours, lasting until dawn.

How much does moonlight matter?

New Moon is at 09:52 on December 9, so around the peak the Moon is a thin crescent. Once it sets in the west in the evening, the sky turns dark.

Checked 2026-10-17; source: KASI monthly astronomical events. The peak time, moonset and sunrise times come from the date cells of the same table.

On both the 13th and the 14th, the Moon sets around 9 p.m., leaving close to ten hours of dark sky until about 7:30 the next morning.

How many will you see?

The numbers from the two sources mean different things.

• KASI's table gives a ZHR of 150.
• NASA says to expect 40 to 50 per hour under dark skies.
• NASA also notes that up to 120 per hour can be seen at the peak under perfect conditions.

ZHR assumes an ideal sky, so the real count is lower. Even so, it is far more than the November Leonids (fewer than 3 per hour, per NASA).

NASA describes Geminid meteors as bright and fast, often yellowish. Their parent body is also unusual: the asteroid 3200 Phaethon rather than a comet.

Where and how should you look?

Here is NASA's advice in order.

1. Get well away from city lights and street lights.
2. Lie flat on your back with your feet facing south.
3. Take in as much of the sky as you can.
4. After about 30 minutes in the dark, your eyes adapt and meteors start to appear.

You do not need to stare at Gemini. NASA also says not to look only at the radiant constellation. Meteors can appear anywhere in the sky.

What should you bring?

It is a mid-December night outdoors, so staying warm matters most.

• Bring a sleeping bag or thick blanket and a folding chair.
• Turn your phone screen to its lowest brightness or switch to a red light.
• Check the Korea Meteorological Administration cloud forecast before you leave.
• Watch for car headlights on dark roads and set up away from the road.

What if the weather is bad?

NASA lists activity until December 17, so the nights of the 13th and 15th are also options. According to the table, the Moon sets before 23:00 through the night of the 15th, keeping the late-night sky dark. If it is cloudy, wait a day or two for a clear night, and check that day's moonset time once more before you go.
