Meteor Shower Calendar 2026–2027 — Peak Dates & Is It Good Tonight?

The annual meteor calendar

Meteor showers are not random events. Every year Earth ploughs through the same ribbons of dust and gravel that comets — and a few shattered asteroids — have strewn along their orbits. The grains strike the upper atmosphere at tens of kilometres per second, heat to incandescence roughly 80 to 120 km above the ground, and flash across the sky in about a second. Because the debris streams keep to fixed orbits, the showers return on almost the same dates every year. That predictability is what makes a calendar worth keeping: you can plan a night out months in advance.

Twelve showers are strong enough to be worth a trip to dark skies. The table below lists all of them with the numbers that matter: when the shower is active, when it peaks, its ZHR, the parent body that supplies the dust, the constellation the radiant sits in, and the speed at which the meteors arrive. Fast meteors leave long, sharp trails; slow ones look like lazy sparks and often flare brighter. Every meteor in a shower appears to stream from one patch of sky — the radiant — because the particles travel parallel to each other and perspective makes them diverge from that point.

Every major meteor shower at a glance

Peak nights are quoted as the two nights when rates climb highest; a shower is usually still strong on the second night. Dates can shift by a day in some years because the dust stream drifts slightly, and the Quadrantids begin in late December and run into January, so they appear twice in a calendar ordered by month.

ZHR is not what you will actually see

Almost every headline about a meteor shower quotes the ZHR — the zenithal hourly rate — and almost every reader then goes outside and counts far fewer. That is not a trick; it is a definition. ZHR is the number a single sharp-eyed observer would count in an hour under two perfect conditions that almost never occur together: the radiant directly overhead, and a sky dark enough to show stars of magnitude +6.5, which means a genuinely rural sky with no light pollution. Change either condition and the count falls quickly.

The two effects multiply. A lower radiant means meteors must cross a thicker slice of atmosphere, and many burn out before reaching you, so the rate scales roughly with the sine of the radiant's altitude above the horizon. A brighter sky hides the faint meteors, and faint meteors outnumber bright ones by roughly 2.5 times for every magnitude you can see deeper. Combined, an honest estimate is:

seen per hour ≈ ZHR × sin(radiant altitude) × 2.5^{(your limiting magnitude − 6.5)}

Take the Geminids, the strongest shower of the year, with a ZHR of 150. From mid-northern latitudes their radiant stands about 75° high at midnight, so sin(75°) ≈ 0.97 — almost no geometric penalty. The real penalty comes from the sky you are standing under:

So the same shower a dark-sky observer counts at well over a hundred an hour yields about 58 from a typical suburb and barely twenty from a city centre. The rule of thumb worth memorising is that your real count is usually one third to one fifth of the quoted ZHR. No telescope or camera changes that — showers are a naked-eye event that fills the whole sky, and a telescope would only narrow your view of it.

Why the Moon decides your night

If ZHR is a shower's ceiling, the Moon is the dimmer switch. A bright Moon raises the background brightness of the entire sky, and faint meteors dissolve into that glow before they ever reach your eye. A full Moon can erase three-quarters of the meteors a shower would otherwise deliver, which is why shower-planning guides always quote the lunar phase for the peak night before anything else.

Two recent peak nights show how much this matters. The Lyrids peak on the night of 21–22 April 2027, when the Moon is full — 100% illuminated and up for most of the night, drowning even their modest rate. The Northern Taurids, by contrast, peak on 11–12 November 2026 with the Moon only 3% illuminated, a nearly dark sky that lets their handful of slow, bright fireballs stand out well. The same kind of shower, two completely different nights.

Lunar illumination independently computed for each peak night at 00:00 UTC and rounded to whole percent.

The lesson is not to skip a shower when the Moon is up, but to set expectations and choose your window. Moonlight hurts most before midnight, when the Moon is often still low; a waning Moon rises late and leaves the early evening dark. The calculator at the top of this page checks tonight's Moon for your city and folds it, the activity window and the distance to the next peak into a single verdict.

How to watch a meteor shower

No equipment is required, but a little preparation multiplies what you see. Meteors arrive at random, so comfort and patience are the real technique.

• Give your eyes 20 minutes. Dark adaptation is slow and chemical. One glance at a phone or a streetlight resets much of it, so leave the screen in your pocket and use a red torch if you need light.
• Get away from city glow. The gain is enormous — the Geminids example above jumps from about 23 to 145 meteors an hour purely by moving to a dark site.
• Lie flat and look up. A reclining chair, a blanket, or simply lying on the ground lets you watch the whole sky without craning your neck.
• Do not stare at the radiant. Meteors right at the radiant are short and foreshortened. Look 30° to 45° away from it and you will catch the long, bright trails instead.
• Watch the second half of the night. As Earth turns you into the oncoming stream, the radiant climbs and rates rise. The best hour is usually between about 2 a.m. and dawn.
• Expect bursts. Meteors do not arrive on a metronome. You may see four in a minute and then nothing for five; an occasional fireball can light up the whole sky.

The Perseids (August)

The Perseids are the year's most popular shower, and deservedly so: they peak in the warm nights of mid-August, when camping and late evenings are easy, and they deliver a dependable ZHR near 100 with plenty of bright, fast meteors. The debris comes from comet 109P/Swift-Tuttle, a large comet that swings through the inner solar system roughly every 133 years; its last pass was in 1992 and its next is in the 2120s. The radiant lies in the constellation Perseus, which climbs high for northern observers after midnight — the reason the pre-dawn hours are so much better than the evening.

Perseid rates are usually quoted for northern latitudes, because the radiant is so far north; from the southern hemisphere the shower is weak and the radiant barely clears the horizon. The peak itself is broad and gentle, spread over a day or more, so timing is forgiving — but a bright Moon at the peak, as in 2027 when it is 77% illuminated, thins the fainter meteors considerably. Plan around the Moon, not the clock.

The Geminids (December)

The Geminids are the strongest annual shower, with a ZHR of 150, and they are unusual in origin: their parent is not a comet but 3200 Phaethon, a rocky object that behaves partly like a comet and partly like an asteroid. Their particles are slower than the Perseids' — around 35 km/s — and often yellow or faintly green, with frequent bright fireballs. Because the radiant in Gemini is well placed for both hemispheres, the Geminids are the one major shower that southern observers enjoy almost as much as northern ones.

Their peak is comparatively sharp, so a single night matters. December's long nights help, but northern-hemisphere weather is the usual obstacle. When the Moon cooperates — as on the 13–14 December 2026 peak, with the Moon only 14% illuminated — the Geminids can keep a steady stream going from dusk until dawn.

The Quadrantids (January)

The Quadrantids carry a high ZHR of about 110 but the sharpest peak of any major shower — a window of only a few hours, so you either catch it or you do not. Their radiant sits in the now-obsolete constellation Quadrans Muralis, near the handle of the Big Dipper, in the modern constellation Boötes. The parent body is the asteroid 2003 EH1, a small rocky remnant that may itself be a fragment of a broken comet.

Because the peak is so narrow, the Quadrantids reward precision. Check the predicted time and the Moon before committing to a cold January night; a full or gibbous Moon at the peak can flatten an otherwise excellent shower. When the timing and the Moon both line up, the Quadrantids throw sudden bursts of bright meteors that make the effort worthwhile.

The Lyrids (April)

The Lyrids are the oldest shower on record, observed for more than 2,600 years, and they come from comet C/1861 G1 Thatcher. Their normal ZHR is a modest 18, so they are not a spectacle in an average year — but they are prized for occasional outbursts that push rates far higher, and for a good supply of bright fireballs against a spring sky with few other attractions.

The radiant in Lyra rises late in the evening for northern observers, so the best viewing is again after midnight. The 2027 peak falls on a full moon, a genuinely unlucky alignment that will cut the visible count to a handful per hour. In a moonless year the Lyrids are a pleasant, unhurried shower rather than a dramatic one — a good excuse to be outside in April.

The Orionids (October)

The Orionids are the second of the year's two showers fed by Comet 1P/Halley, the famous comet that last appeared in 1986 and will return in 2061. Halley's dust crosses Earth's orbit twice a year, giving the Eta Aquariids in May and the Orionids in October. The Orionids are fast — about 66 km/s — and produce long, swift trails that sometimes leave a brief glowing train behind them.

Their ZHR is around 20, but the shower is broad and the radiant in Orion is well placed for both hemispheres, rising around midnight and highest before dawn. Because they are faint and fast, the Orionids suffer badly under moonlight; the 2026 peak on 21–22 October coincides with a Moon that is 72% illuminated, so plan for the hours after moonset or accept a reduced count.

Meteor shower tonight? A five-minute check

Before you drive anywhere, run three checks. First, is a shower actually active tonight, and how far is it from its peak? Second, how bright is the Moon, and will it be above the horizon during the dark hours? Third, is the sky dark where you are going? The tool at the top of this page answers the first two for your city and date in one click and folds them into a plain-language verdict — whether tonight is worth going out for, and what is coming next.

If you are planning further ahead, the moon phase page shows the lunar calendar for the coming week, and the golden hour calculator covers the twilight windows that decide when the sky is genuinely dark.
