The year's meteor showers with the predicted peak in your time zone, the Moon at that moment and, for your city, the best dark-sky window to watch.
The calendar uses the International Meteor Organization (IMO) Working List of Visual Meteor Showers, Table 5 of the 2026 Meteor Shower Calendar, for 12 annual showers: activity period, zenithal hourly rate (ZHR), radiant position and speed. Each year's peak comes from the solar longitude of maximum published by the IMO (262.2 degrees for the Geminids, 140.0 for the Perseids): it is the instant the Sun crosses that longitude. For 2026 this gives August 13 at 02:09 UT for the Perseids and December 14 at 13:49 UT for the Geminids, within minutes of what the IMO calendar states (02h to 04h UT and 14h UT). For other years the number is a projection, and the real peak shifts by a few hours from one year to the next; the IMO publishes adjustments with each edition. What sets it apart is the sky: the tool computes the Moon's phase and illumination at the peak and, with a city chosen, analyzes the two nights around it: how many hours the Sun is below 18 degrees (full darkness), in which of those the Moon is below the horizon and the radiant at least 10 degrees high, and the best window. ZHR is a theoretical ceiling, the meteors per hour an observer would see under a perfect sky with the radiant overhead; in practice, with moonlight, clouds and a low radiant, what you see is a fraction of it. Table 5 of the IMO 2026 calendar gives a ZHR of 150 for the Geminids, and some popular sources still quote 120. Limits: the numbers are those of the IMO 2026 calendar (checked on 2026-11-02) and the 2027 edition may change them. The Moon bands (weak up to 30%, moderate up to 60%, strong above) and the night verdicts are this site's rules of thumb, not the IMO's. The analysis ignores clouds and light pollution.

The top of the tool always shows the next one. In the 2026 calendar, after November 2 come the Southern Taurids (November 5) and Northern Taurids (November 12), the Leonids (November 17 at 23:52 UT, with the Moon at 55%), the Geminids (December 14 at 13:49 UT), the Ursids (December 22 at 22:17 UT) and, in 2027, the Quadrantids (January 4 at 03:34 UT).
