Question 1

How do I embed wttr.in weather on my website?

Accepted Answer

Use the wttr-switcher project to embed a widget, or fetch PNG images with transparency to overlay on pictures using ImageMagick commands like convert, as shown in the PNG format examples with transparency options.

Question 2

wttr.in vs other weather APIs: which is better for developers?

Accepted Answer

wttr.in excels in simplicity and terminal integration with curl, offering pre-formatted outputs ideal for status bars. However, for robust API features, higher rate limits, or commercial support, services like OpenWeatherMap or WeatherAPI might be more suitable.

Question 3

How to get weather data in JSON format from wttr.in?

Accepted Answer

Append ?format=j1 or ?format=j2 to the URL, such as curl wttr.in/London?format=j1, to receive structured JSON data. The j2 format provides a smaller dataset for memory-constrained devices like microcontrollers.

Question 4

Does wttr.in support real-time weather alerts or warnings?

Accepted Answer

No, wttr.in focuses on standard forecasts and current conditions without specific alert systems. For severe weather notifications, you'd need to integrate with dedicated alert services or use more comprehensive weather APIs.

Question 5

Can I use wttr.in offline or self-host it for private use?

Accepted Answer

Yes, wttr.in can be self-hosted by following the installation steps, but it requires internet access to fetch data from WorldWeatherOnline unless you implement caching. The Docker setup simplifies deployment but still depends on external APIs.

Question 6

How to change the language of the weather report in wttr.in?

Accepted Answer

Use the lang parameter in the URL, like wttr.in/Berlin?lang=de, or set the Accept-Language header in your request with curl -H. Over 50 languages are supported, with automatic detection for browsers.
