What a snapshot includes

  • Weather now & next 7 days

    Temperature, feels-like, humidity, wind and gusts, pressure, visibility, UV, sunrise and sunset, plus the next 24 hours and a 7-day outlook.

  • Air quality

    US AQI with a plain-language category, plus PM2.5, PM10 and ozone. Values are modelled estimates, labelled as such.

  • Local time & currency

    The city's own clock and UTC offset, its local currency against the US dollar, and a converter for any pair.

  • Side-by-side comparison

    Put two to four cities in one table, with charts for current temperature and the week's highs.

  • Share, save & print

    Every snapshot and comparison has its own link. Save cities on this device, or print a clean report.

  • No account, no tracking

    No sign-up and no analytics. Saved and recent cities stay in your browser.

Where the data comes from

Each snapshot shows when its data was produced. Nothing is invented. If a source is unavailable, the snapshot says so.
