first writing on a hot sunny day ("writing" does not sound native. I would say "Notebook Entry" because they call it a Notebook on italki.)

I live in Cordoba, Argentina and this is my first entry, because I need more practice and this is a perfect place to do it.
Today is saturday 18 of january and in my city it's a hot sunny day. The temperature it is 43°C. I dont want know how much that is in farenheit but it is a lot. I appreciate your help. and Thank you for reading this me...

Good work! :)
