About this
almanac
A weather journal for any place on earth — the next hour, the rest of today, and the week after that, over a world that keeps changing behind it.
What it does
Forecasts
Three horizons
- Hour by hour — the next 24 hours as a temperature curve you can scrub, plus conditions and precipitation odds for every hour.
- Today in detail — high and low, humidity and dew point, wind and gusts, pressure, cloud, visibility, UV, rainfall and a daylight arc.
- The week ahead — seven days on one shared temperature scale, so a cold snap is visible at a glance.
Beyond the numbers
Air and bulletins
- Weather news — active watches, warnings and advisories straight from the US National Weather Service for whatever place you search.
- Air quality — US AQI with a plain-language band and the underlying PM2.5 reading.
- Search anywhere — type-ahead over a worldwide gazetteer; pick from matches rather than guessing at spelling.
Yours
Made to fit
- Units — Fahrenheit or Celsius, carrying wind, rainfall and visibility with it.
- Light or dark — either, or follow the system.
- Saved places — keep the places you check often one tap away, and set the one that opens first.
- Clock — 12- or 24-hour.
Every preference lives in your browser. Nothing is sent anywhere.
Where the numbers come from
Forecast
Open-Meteo
Current conditions, hourly and daily forecasts, and air quality. Open data, no account, no key — which is why nothing here asks you to sign in.
Bulletins
US National Weather Service
Official watches, warnings and advisories. Coverage is United States only; elsewhere the bulletins panel says so rather than pretending all is calm.
Photography
Wikimedia Commons
The backdrop rotates through twenty-six places — Lofoten, Uluru, Bagan, Salar de Uyuni and more. Every photograph is freely licensed, credited in the corner with a link back to its source, and served from here rather than hotlinked. Use the arrow to skip ahead.
Motion
Live conditions
The sky reacts to the forecast: sun glare and drifting cloud, rain and snow falling at the right density, fog banks, and lightning during a thunderstorm. If your system asks for reduced motion, all of it holds still.
Type
Fraunces & Archivo
A high-contrast display serif for the headline numbers, a workhorse grotesque for everything that has to stay legible at eight pixels.
Still to come
Radar
An animated precipitation layer over a map, so you can see the front arriving rather than reading about it.
Pollen & marine
Seasonal pollen counts, and tide and swell readings for coastal places.
Historical comparison
How today measures against the thirty-year normal for the same date — the part an almanac is actually for.
