Crazy bites or scratches on my arm

I have no idea where they came from but my right arm has scratches or
bites from the back of my hand to my elbow. It isn't itchy, I don't
recall any of the cats doing it. Just weird!

Balcony weather and street weather

How to guess the weather? If I go out onto my balcony (Facing the
street) it always appears cooler than it is, go down to the street and
that's the real deal.
From my balcony today one would have thought I needed a long sleeved
shirt, not so when I went to the street! Sunny and hot!
Went to Parque Rodo to find a shady spot top read. Why shady spot?
Because I got sunburned yesterday on the beach!
