About
About TraceWeather
TraceWeather is a free weather app that shows you what actually matters for your day: hourly humidity, the UV index, dew point, temperature, wind, and barometric pressure — updated every hour, worldwide.
We believe weather apps should be simple and honest: no sign-up, no ads, no clutter. Just the numbers you need, when you need them.
This website is the humidity slice of that idea. It answers one question as fast as a page can load — how humid is it right now, where I am — and gives you the dew point and the next 24 hours of humidity to go with it. Everything is rendered before the page reaches you, so there is no spinner between the search and the answer.

How we build it
No sign-up
Open it, read the number, close it. There is no account to create.
No ads
Nothing between you and the forecast — no interstitials, no autoplay.
No clutter
The metrics that change a decision, not every field the model emits.
Our story — formerly UmeWeather
You may know us as UmeWeather. In 2026 we renamed the app and website to TraceWeather — same app, same weather data, same team, just a new name that better reflects what we do: helping you trace the weather that matters to your day.
If you previously used the UmeWeather app, nothing changes for you — the app update will keep all your settings, and the download link stays the same. Thank you for being with us through the name change.
Weather data & accuracy
Readings come from open forecast and observation data published by national meteorological agencies. We do not model the weather ourselves — we read the same numbers the forecasters publish and present the part of them you asked for.
TraceWeather is an informational tool. It is not a substitute for official forecasts, warnings, or advisories, and it should not be used for aviation, marine, agricultural, medical, or any other safety-critical decision. For severe weather and heat advisories, always defer to your national weather service. Full detail is on the data source section of the home page.
