Simple Weather Dashboard

A single-file, static weather dashboard. Shows current conditions, a 24-hour temperature and rain-chance chart, and a 5-day forecast with scaled temperature range bars. No build step, no backend, no API key — just one HTML file you can open locally or host on GitHub Pages.

Setting the location

The dashboard defaults to Warsaw, Poland, but you can point it at any place via URL parameters — no code edit needed:

Param	Example	Behavior
city	weather-dashboard.html?city=Tokyo	Looks up the name via Open-Meteo's geocoding API and uses the first match.
lat + lon	weather-dashboard.html?lat=48.8566&lon=2.3522	Uses the coordinates directly.
name	...&lat=48.8566&lon=2.3522&name=Paris,%20France	Optional label shown in the header alongside lat/lon. Ignored if city is used (the geocoding result's own name is used instead).
theme	regular or monochromatic
lang	lang=pl or lang=en-US

If none of these are present, it falls back to the defaults defined near the top of the <script> block:

const DEFAULT_LAT = 52.2297;
const DEFAULT_LON = 21.0122;
const DEFAULT_LOCATION_NAME = 'Warsaw, Poland';

Data source

Weather data comes from the Open-Meteo Forecast API — free for non-commercial use, no API key, and CORS-enabled, which is what makes it work directly from a static page.
