Peak window13 August 2026 · 02:00–04:00 UTC

The IMO lists a main maximum between 02:00 and 04:00 UTC. Your best local hour may differ because darkness and radiant altitude change by location.

A practical Perseids viewing plan

You do not need a telescope. A dark, open sky and enough time for your eyes to adapt matter much more.

01

Get away from direct lights

Choose the darkest safe place available. Even moving from a city centre to a rural edge can multiply the number of visible meteors.

02

Give your eyes 20–30 minutes

Avoid phone screens and bright flashlights. Use a dim red light only when necessary.

03

Watch a wide area

Use the direction as a guide, then look 30–60 degrees away from the radiant. Meteors there have longer, more visible trails.

04

Stay for at least one hour

Meteor activity arrives in clusters with quiet gaps. A reclining chair, warm layer, and patience improve the experience.

Transparent methodology

What the score actually measures

The calculator does not invent a fixed “meteors tonight” number. It evaluates the sky in 15-minute steps and finds the strongest two-hour window.

Activity

A date-based Perseids activity model anchored to the IMO ZHR 100 maximum.

Geometry

Radiant altitude, astronomical darkness, Moon illumination, and Moon altitude calculated locally in the browser.

Ground conditions

Your chosen light-pollution level and, when available, cached cloud, wind, and precipitation data.

Perseids 2026 FAQ

Conditions can change quickly. Recheck the calculator on the same day for the latest cloud forecast.

When do the Perseids peak in 2026?

The International Meteor Organization lists the main maximum on 13 August from about 02:00 to 04:00 UTC. The shower is active from 17 July to 24 August.

Will I really see 100 meteors per hour?

A ZHR of 100 describes an ideal dark sky with the radiant overhead. Most real observers see fewer because the radiant is lower, some sky is blocked, and light pollution or clouds reduce visibility.

Can I see the Perseids from the Southern Hemisphere?

The shower is strongest in northern latitudes. Some southern locations can see Perseids when the radiant rises above the northern horizon, but rates are lower and far-southern locations may have little or no useful visibility.

Do I need binoculars or a telescope?

No. Meteors can cross a large area of sky, so the unaided eye gives the widest view. Binoculars and telescopes make the field of view too narrow.

Why is the weather forecast missing?

Forecasts appear only when the selected night is inside the available forecast window. The astronomical result still works for every date in the active period.
