We have temperature from the sensor, but it would be good to know what the weather is like now from an Application Programming Interface (API).
Head over to the website: http://www.openweathermap.org to see for yourself what is information possible to achieve with micropython or any python code.
This is a fun bit of code to help you explore for yourself.
