Show HN: Beautiful intuitive weather forecasts that don't rely on numbers/units

https://weather-sense.leftium.com
2•Leftium•4h ago
- Visualize weather metrics via space and colors

- Compare current/future conditions with weather you experienced the day before

- Understand/compare how conditions change throughout the day

---

WeatherSense started out as a hand-coded project: https://github.com/Leftium/weather-sense

- Would you consider this project a good example of how AI can be used to enhance coding?

- Claude helped implement many new features from the backlog, like 60-min precipitation forecasts

- Claude helped add some whimsical features: I only considered adding because AI experimentation is cheap:

* "Calm mode:" truly emphasizes how WeatherSense doesn't need numbers by removing/replacing all numbers from UI

* Dynamic background color based on sun angle (time + location)

---

Major inspirations:

- DarkSky

- MerrySky (https://merrysky.net)

Any way to change units? My location uses the metric system.
Leftium•3h ago
There is a unit toggle button right below the day tiles. Your selection should be persisted across page loads.

- You can also tap any unit to toggle.

- But the main point of WeatherSense is to transcend units ^^

It is not beautiful for me on Mobile
Leftium•1h ago
Can you clarify? Is the rendering broken on mobile?

I just checked, and the responsive layout seems to render correctly on Android Firefox/Chrome and iOS Safari.

You can even save WeatherSense to your home screen as a simple progressive web app.

Cider9986•1h ago
I don't like the color scheme with the gradients; nothing functionally wrong, just my reaction.
Leftium•44m ago
The gradients actually serve a purpose:

- You can see the weekly high/low temperature trends by scanning down vertically along the left.

- Redder color means warmer; bluer means cooler.

- The gradient is constant for all data plots, so you can visually compare the temperature across days and hours.

- The gradient block for each day goes from the high to the low temp for that day.

- Even the hourly temperature plot line is calibrated to the same gradient.

---

The sky background gradient is slightly superfluous, but it's very subtle and meant to emulate (a more vibrant) version of the actual sky.

For anyone who wants more gradients: there's a setting here: https://weather-sense.leftium.com/wmo-codes

I disabled those by default because they were distracting and didn't serve a purpose.

Interesting idea — feels very intuitive.

Curious though: do users miss the numbers when they need precise decisions?

Leftium•11m ago
The numbers are still there (unless "calm" mode is enabled.) You can scrub any of the plots to get the precise values for the metrics at that time.

The colors + space simply help you understand the numbers better.

(Weather forecast precision is artificial "because weather forecasts fundamentally have very high uncertainty and error bands"[1])
