Meteor showers from 300 cities

What is on a city page

Each page works through all twelve tracked showers for that location and ranks them by what you could actually expect to see there, not by their published zenithal rates. For every shower it gives the local peak date, the hours between the end of astronomical twilight and the start of dawn, how high the radiant climbs while it is dark, how much of that window the Moon spoils, and the resulting hourly rate. Where a radiant never rises far enough to matter, the page says so plainly rather than printing a number close to zero.

The 300 cities span 83 countries and 103 distinct time zones, which is the point of covering them individually: time-zone offset, latitude and the date line interact, and a shower peaking at 03:00 UTC lands in a different part of the night — often a different calendar date — in each of them.

Selection is by metropolitan population, largest first, which is why the list is dense in Asia and thin across the Sahara and the Arctic. If your own city is not here, the shower pages carry the same working for any coordinate you supply, and the decision card on the home page resolves your approximate location automatically.
