REVIEWED CITY COVERAGE
Stargazing Visibility by City
This page answers one city at a time using live geocoding and forecast data. Dedicated static forecast pages are available only for cities with reviewed demand and reliable data coverage; Starry Forecast does not publish indiscriminate, low-value city pages.

CRAWLABLE TOOL EXPLANATION
What a city result contains
The live result resolves one submitted city to coordinates and requests its current weather and twilight context. It reports a planning score with the underlying cloud, humidity, visibility, Moon and darkness factors. A limited set of reviewed cities also has an hourly cached page; other searches remain live rather than becoming thin permanent pages.
Moon phase and twilight use location and time.
Streetlights, terrain, smoke and safety are not fully captured.
These are interpretation examples, not live conditions. Review the methodology and source register.
Why this is not a city-page factory
City pages can become thin and duplicative if generated without evidence. Starry Forecast adds a dedicated city page only after demand, data coverage and usefulness are reviewed, while this live checker serves all other locations without uncontrolled page growth.
