REVIEWED CITY COVERAGE

Choose a city forecast

Start with a dedicated forecast for tonight and the next seven nights. This directory helps you choose a destination; it is not a second version of the search tool.

Find a darker place to observe

Search your destination on a light-pollution map, or browse certified Dark Sky Places. These are external planning resources, not additional live forecast data.

A dark map color does not guarantee clear skies, legal nighttime access or safety. Check the map layer and date, then confirm opening hours, permits, transport and local conditions with the site's operator. These links do not send your coordinates automatically.

Planning somewhere else?

The tonight and seven-night planner searches other cities without creating permanent pages for each query. Include the country or region for ambiguous names and check the resolved location before using the result.

Need only the weather at the current moment? Use the current-conditions checker. A current snapshot is not the same as tonight’s best three-hour window.

Why this is not a city-page factory

We keep dedicated coverage to four reviewed cities. A new city needs reliable data, useful local interpretation and checked observing-site information, not just a changed place name. Other locations remain available through the planner.

Four cities, four different observing plans

Tokyo

Parks can offer open urban horizons and occasional organized sessions; past events do not establish nightly telescope access.

London

Urban parks offer wide views, but layered cloud, short summer darkness and seasonal deer-management closures need planning.
