# MagTag Daily Weather Forecast Display ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/132/889/medium800/wireless_banner.jpg?1728319483) Is the weather outside delightful? Or is it frightful? And what about in the coming days? In this guide we'll show you how to use an [Adafruit MagTag](https://www.adafruit.com/magtag) to create a weather display for today and future conditions. Using the MagTag's WiFi capability, we connect to a weather API service and get weather information. We then parse that and display it up in a nice summary. Deep sleep is also used to only run the update once a day around midnight, so we can run for many weeks on one charge. ## Weather API Services The original code for this guide used the free [weather API service](https://openweathermap.org/api) provided by [OpenWeatherMap](https://openweathermap.org). There have been several updates to the code to keep up with API changes. However, OpenWeather now requires credit card information to obtain an API key - even if only using the free API access. **As a result, this guide no longer uses the OpenWeatherMap API**. The old code is still provided for reference. The current version of this guide is based on the [weather API](https://open-meteo.com/en/docs) provided by [Open-Meteo](https://open-meteo.com/). This is a truly free weather API which currently does not even require an API key. It is also open source, with the code available in a [GitHub repo](https://github.com/open-meteo/open-meteo). This isn't a 100% drop in replacement in terms of weather forecast information provided. As a result, there are some minor differences relative to the original version. ## Parts Here are the parts you'll need for this project.
