Vilnius Forecast Screensaver
The Vilnius Forecast screensaver draws temperature, felt temperature, wind and precipitation for Vilnius from LHMT, the Lithuanian hydrometeorological service, rather than from a commercial aggregator. The solid line is air temperature, the dashed line is what it feels like, and the bars underneath are rainfall. It runs in the browser with nothing to install; press ESC to exit.
How the Vilnius Forecast screensaver works
The saver reads api.meteo.lt, the open forecast API of the Lithuanian hydrometeorological service.
No account and no key: the request goes straight from your browser, or from this site's own refreshed copy of the feed where the source does not allow browser access.
Values are drawn on a canvas that resizes with the window, so it works on a laptop or a wall display.
If the source is unreachable the saver says so on screen rather than showing stale numbers as though they were current.
A worked example
The temperature line runs across the next day or so with the hour labelled beneath every few points. A dashed grey line tracks alongside it: in summer the two nearly overlap, but on a windy winter afternoon the dashed line sits several degrees lower — that gap is wind chill. Blue bars along the bottom mark the hours with precipitation in the forecast.

Frequently asked questions
- Why the national service instead of a big weather app?
- Because it is the primary source. LHMT is the body that actually issues forecasts for Lithuania, publishes them openly with no key, and does not reformat or resell somebody else's model output.
- What is felt temperature?
- It combines air temperature with wind and humidity to estimate what the body experiences. It diverges most from the air reading in cold wind, which is exactly when the difference matters.
- Is this real data?
- Yes. It comes from api.meteo.lt, the open forecast API of the Lithuanian hydrometeorological service. Nothing is invented or simulated, and if the source cannot be reached the saver reports that instead of drawing something plausible.
- Does it cost anything or need an account?
- No. Every screensaver here is free, runs in the browser and needs no sign-up. This one uses a public API that requires no key.
