Huecast

How Huecast works

The weather as a picture: one circle, one sky and a few words. Everything on screen is drawn from the forecast for that place and hour. There are no photos and no icons.

01The circle

By day the circle is the sun, and at night it's a ring: the moon. The hotter it gets, the more the sun pulses and glows. Behind thick cloud or fog it dims and goes soft. At night the stars pulse softly. Below −5° a faint ice halo rings the sun or moon, stronger the colder it gets.

02The sky

The background mixes two colours in a diagonal gradient: one for the time of day where you are, one for the temperature.

Below zero the sky turns ice blue: deeper the colder it gets, pale frost blue at 0°. Three things adjust the colours. At night the sky darkens but keeps its colour, so a freezing night is deep blue and a mild one stays warm. Clouds, fog and rain take colour out of the sky, while snow makes it brighter. On very pale skies the text turns dark so it stays readable.

03The weather

The weather is drawn live on top of the sky. Each kind has steps, set by the measured amount in the forecast: heavier rain falls faster and longer, heavier snow has bigger flakes, thicker fog rises higher, and stronger wind adds streaks and slants the rain.

07Data & privacy

Forecasts come from Open-Meteo. City names come from BigDataCloud and Open-Meteo. Your location is only sent to them to get the forecast. Huecast has no server, no account and no tracking. Pinned places, your °C/°F choice and your last place are saved in this browser only.
