Perseid meteor shower 2027

When and where to look

The best night is the night of 12 to 13 August. Best after midnight from the Northern Hemisphere, on warm summer nights.

The meteors seem to come from the radiant, in Perseus, near its border with Cassiopeia, but they appear all over the sky. Look about halfway up and 40 to 60 degrees away from it, where the trails are longest.

From	Radiant at its highest
London	84°
New York	73°
Delhi	61°
São Paulo	9°
Sydney	below the horizon

The higher the radiant, the more meteors you see. When it is low, the ones you do see skim the horizon in long, slow trails.

The Moon

An 86% Moon washes out all but the brightest meteors.

Up to 100 an hour is the rate under a perfectly dark sky with the radiant overhead. From a typical dark site expect a third to a half of that; from a town, a handful.

What is happening

Every year the Earth crosses a stream of dust shed by Comet Swift-Tuttle (109P). The grains, most no bigger than sand, hit the top of the atmosphere at 59 km/s and burn up 80 to 120 km above the ground, each one a streak of light.

Because they all arrive on parallel paths, perspective makes them seem to spread from one point, the radiant, like a road vanishing into the distance. They are named after Perseus, the constellation their radiant lies in.

How to watch

• Get away from lights. A dark field or hill outside town shows several times as many meteors as a garden in the city.
• Give your eyes 20 to 30 minutes to adapt, and keep your phone screen dim or red.
• Lie back on a reclining chair or a mat and take in as much sky as you can. No telescope or binoculars: they show too little sky.
• Be patient. Meteors come in bursts and lulls; give it at least an hour.
• To photograph them, put a phone or camera on a tripod, point it about 45 degrees from the radiant and take long exposures one after another.

Questions

When do the Perseids peak in 2027?

The peak is predicted for 13 August 2027 at 08:13 UTC. The shower is active from 17 July to 24 August, so the nights either side are worth watching too; the best is the night of 12 to 13 August, after midnight.

How many meteors will I see?

Up to about 100 an hour under a perfectly dark sky with the radiant overhead. Most watchers see a third to a half of that from a dark site, fewer from towns.

Will the Moon spoil it?

An 86% Moon washes out all but the brightest meteors.

Where should I look?

Anywhere, though meteors appear longest 40 to 60 degrees from the radiant, in Perseus, near its border with Cassiopeia. Look about halfway up the darkest part of the sky.

Do I need a telescope?

No. Meteors are best with the naked eye: binoculars and telescopes show far too little sky.

When are the Perseids next?

12 August 2028, with the peak at 14:22 UTC and a 59% Moon.
