Why the view from Sendai is different
Sendai sits at 38°N. Showers with a far-northern radiant climb high overhead here, while some southern-sky showers barely clear the horizon or don't rise at all.
Meteor showers in Sendai, month by month
The whole year from Sendai’s latitude at a glance — each month’s headline shower, its peak night, and how the moon treats it. Quiet months are shown honestly: part of the sky’s calendar is simply empty, and knowing that saves you cold nights.

Two patterns in the table are worth a second look. First, the moon column reshuffles the year every year: a shower that fought a full moon last season may get a black sky this one. That is why the ratings above are computed fresh for Sendai and this year’s geometry — not copied from a fixed almanac that ages badly.
Second, latitude is destiny. From 38°N, some radiants simply ride higher than others ever can, and a modest shower with a well-placed radiant will quietly outperform a famous one that never clears Sendai’s rooftops. When the table disagrees with a headline, trust the table — it knows where you live.
Where to watch near Sendai
You don’t need a mountaintop — you need darkness and an open view. From Sendai, drive out of the glow: even 30–45 minutes past the edge of the city typically buys you two sky classes of darkness, which is the difference between counting a handful of meteors and counting dozens. Parks, lake shores, farm roads and beaches all work. What matters is a wide horizon — meteors streak across the whole sky, not just around the radiant — and no direct lights in your eyes: one parking-lot lamp can undo twenty minutes of dark adaptation.
For the Southern Delta Aquariids, the radiant climbs the south sky over Sendai and tops out at 35.4°, so pick a spot where that direction is open to the horizon. Then look slightly away from it — trails appear longest 40–60° to either side of the radiant. Give your eyes twenty minutes to adapt, keep the phone dim, and dress a season warmer than the forecast suggests: meteor watching is sitting still outdoors at night.
If leaving town is not an option, you can still rescue the night. Find the darkest pocket the city offers — the interior of a large park, a waterfront with the river between you and downtown, a hill that puts the glow at your back — shield your eyes from every direct lamp, and accept that you are playing for the bright end of the shower. Fireballs shrug off light pollution far better than the faint majority does, and one good fireball pays for the whole evening.
Photographing meteors over Sendai
Meteors photograph better than they look — a camera collects light for seconds at a time while your eye cannot. The classic recipe: a wide, fast lens (14–24 mm at f/1.8–2.8), 15–25 second exposures, ISO 1600–3200, manual focus locked on a bright star, and an intervalometer firing continuously. Over one peak-night hour that is roughly 150 frames; expect meteors in a handful of them — and, on a good night, one frame you’ll keep forever.
Point the camera 40–60° away from the radiant — south of Sendai on the peak night — so the trails cross your frame at their longest. Keep some foreground in shot: a treeline or a skyline anchors the picture. Moonlight is the main spoiler; with the moon at 100% on the Southern Delta Aquariids peak, keep it behind you and shorten exposures by a stop.
Reading the numbers
What is ZHR?
Zenithal Hourly Rate — the standard yardstick for a shower's strength. It's how many meteors one observer would count per hour under a perfectly dark sky with the radiant directly overhead. A lab condition, not a promise: your real count is always lower.
Why will I see fewer than the ZHR?
Three honest discounts. The radiant is rarely overhead — at 30° altitude half the meteors never clear your horizon. The sky is rarely perfectly dark — city glow and moonlight wash out the faint majority. And clouds take their cut. That's why we quote a realistic range for your sky instead of the headline number.
What is the radiant?
The point the meteors appear to stream away from — pure perspective, like snowflakes fanning out from ahead when you drive through snow at night. Don't stare at it: trails look longest 40–60° away from it. What matters is its height — the higher the radiant, the more meteors above your horizon.
What does the speed (km/s) change?
The look of the show. Fast showers — the Leonids hit the atmosphere at 71 km/s — draw thin, quick streaks that often leave glowing trains. Slow ones, like the 27 km/s Taurids, roll across the sky as long, bright, sometimes orange fireballs.
Dark window vs. best window
The dark window is pure astronomy: the stretch between dusk and dawn when the sun sits far enough below the horizon. The best window is the practical answer — the hours holding at least ~70% of the night's top rate, when it's genuinely worth standing outside.
What is a parent body?
Every shower is the dust trail of one comet or asteroid. When Earth crosses that trail on its yearly lap, the grains burn up as meteors — the Perseids are crumbs of comet Swift–Tuttle, the Geminids of asteroid 3200 Phaethon.
Common questions about Sendai
When is the next meteor shower in Sendai?+
The Southern Delta Aquariids, peaking on the night of July 30, 2026 local time.
What's the best meteor shower to watch from Sendai this year?+
The Geminids — its radiant climbs highest above Sendai's horizon this year with the least moonlight in the way, so it's the best bet for peak rates.
How many meteors will I actually see from Sendai?+
During the Southern Delta Aquariids peak, expect roughly 1–2 meteors an hour from Sendai’s suburbs, 1–1 from the bright city core, and 1–2 under a properly dark sky within driving distance. The gap is light pollution, not the shower.
Where in the sky should I look from Sendai?+
Face roughly south. The Southern Delta Aquariids radiant stands highest over Sendai around 01:41, reaching 35.4° — but don’t stare straight at it: the longest trails appear 40–60° to either side.
Will the moon spoil the Southern Delta Aquariids from Sendai?+
On the peak night the moon is 100% lit (full moon). Bright enough to wash out the fainter half of the shower. Keep the moon at your back, watch the darkest quarter of the sky, and trust the honest per-sky range above rather than the headline rate.
Is anything visible from Sendai tonight, before the peak?+
Usually yes. Showers run for days to weeks around their maximum, and the sporadic background adds a few meteors an hour on any dark night. The “Tonight” panel above computes the coming night for Sendai specifically — what’s falling, the best window, and whether the clouds will allow any of it.
How many meteor showers can you see from Sendai?+
Of the eleven major annual showers, 11 are visible from Sendai's latitude this year, though cloud cover and moonlight decide how many meteors you'll actually count on any given night.
Do I need to leave Sendai to see a meteor shower?+
You don't need to, but it helps a lot. City light pollution washes out all but the brightest meteors — driving even 30–45 minutes to a darker sky can turn a handful of sightings into dozens.
